Topic 6 (Information Transfer)
ANSWERS MUST BE SEND THROUGH EMAILS (mrsmgerik3052020@gmail.com) Question 1 Read the following text Then, answer questions (a) – (j) There are various breeds of cats all over the world. We have called them our friends for about 8,000 years. Cats are popular pets in Malaysia because of their independent nature. They are easy to care for and require minimal supervision for long periods of time as long as there is enough food and fresh water. They also offer companionship. Besides, in Malaysia we do not need a licence to keep a cat. Having a cat as a pet can be very helpful. By keeping a cat, children can learn about responsibility. Cats cannot tell time but they can stick to a schedule. They generally eat, sleep and play at around the same time daily. Thus, children can learn time management by observing their cats. Furthermore, by seeing to their needs, children develop a caring attitude. Most cats spend hours grooming themselves. This passion for cleanlines...

ReplyDeleteDengue fever is a mosquito-borne virus affecting more than 100 million people each year.Dengue viruses are transmitted to humans through the bites of infective female aedes mosquitoes.The mosquitoes have 4 life stages.The entire life cycle,takes approximately 8 to 10 days.Firstly,the aedes mosquitoes will lay eggs on the inner and wet walls of containers in stagnant water.It only takes a small amount of water to lay eggs.She can produce 100 eggs at a time.
When the eggs hatch,larvae will emerge ,but only when the water level rises to cover the eggs.This means when someone add water or rainwater fall in the container,it will trigger the larvae to produce.After that,the larvae becomes pupa and develops until the body of the newly formed adult produce.
The transmission is through mosquitoes that acquire the virus while feeding on the blood of an infected person.After virus incubation,an infected mosquitoes is capable.There is no way to know the mosquitoe is carrying the virus.Infected female mosquitoes also transmit the virus to their offspring.
The infected mosquitoes or aedes mosquitoes will carry the virus to the healthy person,so the person will be infected .If the uninfected mosquitoes bite the person,the mosquitoes will carry virus to the other people.The cycle will be repeated .
There are currently no vaccines.The best method of prevention is to avoid mosquitoes bite.To avoid the disease we must wear long-sleeve shirts and long pants.Second ,please damage the stagnant water or cover the water containers.Next,we have to keep our enviroment clean.I hope that the disease will have a solution soon.

ReplyDeleteDengue is spread through the bite of the female Aedes mosquito which is aegypti. Infections of one type of virus will give community to the virus alone, if the person lives in the area of dengue, they can be infected for more than once throughout their life. Female mosquitoes lay eggs in the stagnant water. The eggs are black and oval in shape. It also laid singly above water surfaces of the container.
Eggs are ready to hatch from a few days to several months after being laid. Eggs hatch in batches, a process that may last days or weeks, since some eggs require multiple soakings in water before hatching. Larvae are aquatic and develop into pupae in as little as five days. Pupae then develop into adult female flying mosquitoes in two to three days.
Aedes aegypti is a day biting mosquito. That means that the mosquito is most active during daylight, for approximately two hours after sunrise and several hours before sunset. When a mosquito bites a person who has dengue virus in his or her blood, the mosquito becomes infected with the dengue virus. Also, an infected person that suffering from dengue fever can infect other mosquitoes.
An infected mosquito can later transmit that virus to healthy people by biting them. Dengue can't spread the disease from one person to another, and mosquitoes are necessary for transmission of the dengue virus. Humans are known to carry the infection from one country to another or from one area to another during the stage when the virus circulates and reproduces in the blood system.
How can we prevent dengue fever? The most effective prevention is wearing long sleeves clothes to protect ourself from mosquitoes bites. Second prevention is removing water from coolers or covering the water containers at least once a week. To get rid of mosquitoes around the house and keep them away from us, use mosquitoes repellents. Important for us to keep the environment clean. Lastly, I hope we can cooperate in reducing the rate of transmission of dengue.

ReplyDeleteDengue fever is a mosquito-borne tropical disease caused by the dengue virus. The symptoms begin three to fourteen days after infection. These may include sudden high fever, pain behind eyes, fatigue and vomiting. Time to recovery generally takes two to seven days.
The main caused is from aedes mosquito that lay eggs at the polluted area and also at stagnant water. If we don't take responsibility, the mosquito will lay their eggs. The life cycle of aedes aegypti can be completed within one and a half to three weeks weeks. It also will produce on average 100 to 200 eggs per batch and also produce up to five batches at one time.When the eggs hatch within two to seven days it will become a larvae. After 4 days become larvae it will turn to pupae and adult in two days. The life cycle also depent on environmental conditions.
When they become an adult mosquito, they will bite a healthy human. Therefore, humans that exposed to mosquito's bites will cause dengue fever. So if someone had early symptoms of dengue fever, they must immediately meet with doctor to get early treatment.
Dengue cannot be spread directly from person to person. However, a person infected and suffering from dengue fever can infect other mosquitoes. Humans are known to carry the infection from one country to another or from one area to another during the stage when the virus circulates and reproduces in the blood system.Unfortunately, aedes aegypti has evolved into an intermittent biter and prefers to bite more than one person during the feeding period. This mechanism has made Aedes aegypti a very highly efficient epidemic vector mosquito. So it will increase the number of people that have dengue immediately.
Therefore, what is the best action to reduce the dengue fever? All people need to be responsibility for cleaning the house. It is because the dengue fever started with the lazy attitude of community. For the example, they need to clean the area that had stagnant water because mosquito will not get breed in that area quickly. Therefore, we need to cooperation with other people to having a gotong-royong at every park for keep clean. In fact, the dengue fever cases will decrease.

ReplyDeleteDengue fever is a disease caused by aedes mosquitoes. These aedes mosquitoes thrive in stagnant waters. Mosquitoes will lay eggs in the area. Mosquito eggs only take 7 days to become adult mosquitoes . The stagnant water area is actually caused by our own because we do not maintain the hygiene of our surroundings and cause water reservoirs there to increase the breeding of aedes mosquitoes.
Next, the egg will undergo the process of hatching eggs and becoming larvae . It then becomes a cocoon and eventually becomes an adult mosquito. The mosquitoes that transmit the dengue virus and bite humans are the female aedes mosquitoes, the Aedes aegypti and Aedes albopticus.
Mosquito bites that carry the dengue virus can cause someone to have dengue fever. Then, a person may have some symptoms such as muscle aches and joints, vomiting, diarrhea, fatigue, back pain, and headache. Those who have these symptoms should see a doctor immediately.
Aedes mosquitoes carry a dengue virus in their body and it will bite the healthy person and cause them to have dengue fever. Aedes mosquitoes will continue to carry the dengue virus and will bite healthy people. This causes a case of dengue fever if we do not prevent the aedes mosquitoes.
Therefore, the best way to reduce this dengue fever is to prevent aedes mosquitoes. One of the way is we must ensure that there is no breeding ground for aedes mosquitoes. We need to remove containers that have stagnant water, remove stagnant water in flower pots to prevent larvae breeding. Next, we should use insecticide to kill mosquitoes. We should not forget to wear long-sleeved shirts and trousers while outdoors to protect ourselves from these aedes mosquito bites. Last but not least , I hope we can prevent this dengue virus from being spreading in our country.

DeleteAdult mosquito will find a stegnant water to lay eggs.It will produce within 200 to 300 eggs.After it finish , it will go to find a new person to bite and let it's eggs .
After a few days, the eggs will become a larvae and then pupae and finally become a mosquito. The life cycle of mosquito usual need 7 days.
When it become adult mosquito, it will bite another person.Actually, not all mosquito become the aedes mosquito,it happen when it bite a person who had Dengue fever.
When it bite that person, it will carry aedes virus .Usually the number of mosquito will become higher at the evening.We know that a healthy person will ecxercie that time and the mosquito will bite them to transfer the virus.
In conclusion, we need to find a way to prevent the this virus to ensure the number of the person who had that virus become low . For example, we can wear a long sleve to prevent from mosquito's bite and remove all the stagnant water at the area of oir house.

ReplyDeleteNowadays many people suffer from dengue. Dengue is the most common viral illness around the world caused by a small mosquito. Dengue fever is a quite dangerous disease that can mainly be found in the tropics. Regrettably, it can lead to the serious medical problem. To make the picture clearer, dengue fever is not caused by every mosquito. In fact, it is caused by the AedesAegypti mosquito which carries deadly virus.
Most of the type of mosquito will lay their eggs on the surface of stagnant water. But for the Aedes mosquito lay their eggs on damp soil that will be flooded by water. Most eggs hatch into larvae within 48 hours. During the fourth molt the larva changes into a pupa. When development is complete, the pupal skin splits and the adult mosquito emerges. The newly emerged adult rests on the surface of the water for a short time to allow itself to dry and all its body parts to harden. The wings have to spread out and dry properly before it can fly. Blood feeding and mating does not occur for a couple of days after the adults emerge.
After a couple of days, the Aedes mosquito ready to transmits the viruses that cause dengue. The viruses are passed on to humans through the bites of an infective female Aedes mosquito, which mainly acquires the virus while feeding on the blood of an infected person. This dengue disease also can be spread to the healthy person by meet the other person that carries the virus.
It is very important to take precautions inside and outside the house to prevent mosquito breeding and contribute to dengue prevention. The important things that we should do is cover all the water containers around the house and keep the environment of the house is clean.

ReplyDeleteWhen mention aedes fever, of course we can't avoid talking about aedes mosquitoes. Aedes mosquitoes are very dangerous especially when they lay eggs in the stagnant water near home.
The eggs hatch in 2 to 7 days and become larvae. Then, in a week it will be a cocoon. After two days, the mosquito will come out of its cocoon.
One of the most common ways of spreading dengue fever is when mosquito bites someone who is infected with the disease.
The mosquito will carries the virus that contain in its body. This desease will spread by mosquito bites especially a healthy person.
That is why it is important for us to prevent it. The easy way to do prevention is we must cover water containers to avoid mosquito lay eggs and keep environment clean from other diseases.

ReplyDeleteDengue fever is one of the most dangerous disease and it also lead to death.It cause by aedes mosquito that carries the dengue virus.Aedes mosquito lay it eggs in stagnant water.It will hatch after 2-7 days .
When the eggs hatch,the larvae will emerge and live in the water before the pupae stage.the larvae will transform into pupae after 4 days.The pupae transform into mosquito completely after 2 days.
How it becomes aedes mosquito?The mosquito that bite infected person carries the dengue virus and it will bite the healthy person and that is how the virus spread among people.This is why we need to keep our hygiene so that we can avoid from aedes mosquito breeding in our house.How to prevent it from happen is we can cover the water container so it Won't breeding in the water container and keep our environment clean.After all, preventation is better than healing.
Dengue fever is a dangerous disease that can cause death.It cause by the aedes mosquito.This mosquito lay their eggs in the stagnant water at dirty places.A female mosquito can produce 100 eggs at a time.
ReplyDeleteWhen the eggs hatch, the baby of the mosquito called larvae will live in the stagnant water.After a few days,it will become pupa and developed to become a mosquito.They will fly away and leave their home.
A mosquito needs food to continue its life.So,they will bites human to get bloods that contain energy and nutrient for their body.The infected person wil get a fever and a headache after get bitten by an aedes mosquito.
If the infected person didn't go to the hospital,the person that carries the virus will spread the virus to a healthy person.Maybe the person can get the virus and sprrad to the other people.
Finally,we must prevent the dengue virus from spread to all the people around the world.So,we must clean and cover the containers to stop the mosquito from laying the eggs.For the conclusion,we should keep environment clean to get a healthy life.
Dengue fever is a desease that can bring death. This desease comes from aedes mosquitoes. The population of aedes mosquitoes increase when people dont alert with surrounding's cleanliness. Aedes mosquitoes comes from stagnant water. They will lay eggs in stagnant water or drains.
ReplyDeleteThe eggs hatch will changed into larvae and stay in stagnant water for a while. The process of being adult mosquito only takes a week. That is why we should not let the water stagnate. We should makesure our home surrounding doesnt have stagnant water or dirty places full with rubbish.
When the mosquito turns into adult, they will fine human as their prey to get blood. Their bites will infect person. The person that infected by aedes mosquitoes bites will get fever. The first sign of dengue fever is muscle pain and high temperature of body. Symptoms usually start 4 to 7 days after you are bitten by mosquitoes.
The person that has dengue fever should stay at home. They cannot go everywhere or be close with other person. This is because the person that infected by mosquitoes bitten carries virus and will spread it. Healthy person will also get this desease.
There are some steps that we should follow to prevent dengue fever vibes. We must cover water containers to avoid water stagnate. We should keep our environment and house surrounding clean and neat. That is why we should held gotong royong at school, village and home to prevent dengue fever.

ReplyDeleteDengue fever is a disease caused by aedes mosquito that thrive in and near human lodging.Aedes mosquito usually lay it eggs in stagnant water.Most mosquitoes lay their eggs directly into water.
Then,the eggs ready to hatch from a few days to several months after being laid.Eggs hatch into larvae when submerged in water.Larvae are aquatic and develop into pupae in as little as 5 days.The last process is pupae develop into adult flying mosquitoes in 2 to 3 days.
Next,when the mosquito bites someone,the person is infected with dengue fever.The infected person will show the symptoms within 2 to 3 days.Dengue fever will cause a high fever and one of the symptoms is headache,vomitting and pain behind the eyes.
After that, if the mosquitoe bite the infected person,the mosquito is infected.The infected mosquito will carries the dengue virus and it will bite a healthy person.So,the effect is it will spreads the disease.
Lastly,there are many ways to prevent dengue fever.As we know,prevention is better than cure.One of the ways is we need to cover water container to prevent stagnant water.We also need to keep our environment clean such as held gotong - royong activity in our place.I hope we will safe from this disease.
Dengue fever once have became an outbreak on Malaysia. It is basically a disease that caused by Aedes mosquitoes. When someone is bitten by an Aedes mosquitoes, it is the time for human defense system to fight the bacteria. When a person got infected, he is most likely to have a long period of fever, cold and body muscle usually contracts and make it hurtful.
ReplyDeleteThe Dengue fever is not a usual disease that come and go, instead it is one of the reasons why population of humanbeing decreased. It can cause death. To prevent this disease from spreading we can take some prevental steps. One of the steps we can take is to make sure your house is clean from stagnant water. Stagnant water is the perfect place for Aedes mosquitoes to breed an eggs and ended up creating new mosquitoes. Secondly, make sure to do a gotong royong on your housing area with the neighbourhood. By this, we can destroy the houses of mosquitoes breeding and stop the disease from keep spreading.
In a nutshell, we can also take small measurements of prevental steps such as reduce going out in about mid-evening around 7 p.m. until 8 p.m. because that is the time where mosquitoes actively flew to all area finding his food. Make sure to stay safe and be clean.

ReplyDeleteDengue fever is one of the dangerous fever that can cause death. It is cost by aedes mosquitoes that carries the dengue virus. The mosquito lay their eggs in stagnant water.
When the eggs hatch, the baby mosquito called larvae will emerge and live in the water before it transform into pupae. The transformation will take about four days time. After that, the pupae will transform into adult mosquito after two days.
The adult mosquito needs blood that contain energy and nutrient to stay alive. Therefore, they will take the blood of a human by biting them. The human bitten by the mosquito will be infected. The infected person will get headache cause by the bite.
If the infected person does not take precautionary steps, the person that carries the virus will spread it to a healthy person. This will cause the virus to spread.
Finally, we need to prevent the virus from spreading around the world. So, we must clean up the water container and clean the drain to prevent blocked drain that can cause stagnant water. For the conclusion, we need to keep the environment clean for healthy life.

ReplyDeleteAs we all know, Dengue fever is one of the most dangerous disease that ever exist in this world. Dengue occur because of the existence of the virus carrier which is Aedes mosquitoes. Now, how did these mosquitoes breed and how can they infect people?
These mosquitoes will lay their eggs in the stagnant water in used water bottle, used empty can and others. They also may breed in clogged drains. The main medium for them to multiply themselves by laying eggs is water. After they have laid their eggs, the eggs will hatch after one week and the larvae will be formed. This larvae will live in the water for a few more days before they all turning into the third stage of their life which is pupae. Only not long after that, the mosquitoes will emerge and they will start to find something to feed themselves. All of them need blood to stay alive and energetic. So, that's why they are everywhere to bite humans for the sakes of getting themselves fed by human blood.
Now, we're going to see how these tiny mosquitoes might gave us a big impact of Dengue fever or virus. The adult mosquitoes might have bitten an infected person and carry the virus right away in their body before biting those who are not infected and healthy. So, this is the real way of how do this Dengue virus being spread up around the world. There will be some symptoms for those who are infected to this virus so that they can be aware of their health condition and refer to the doctor immediately. The symptoms are such as a very high body temperature due to fever, having red rashes on some part of their body and others.
There are some ways that all of us can do as a community to stop and prevent the spread of this well known virus that may lead towards death. First of all, throw away any stagnant water from the container. Other than that, you also can cover every water containers with something so that it is cover up to prevent the mosquitoes from laying their eggs in them. You also need to kill the larvae by using the larvae poisons and lastly, You need to regularly change the water in your flower vase in terms of keeping your house safe from these mosquitoes.
In the conclusion, we all need to be aware and need to extremely careful with this kind of thing. In this kind of situation we are not just need to think about our own selves but we need to think for others good too.

ReplyDeleteDengue virus is the cause of dengue fever.The virus is spread by aedes mosquito.The mosquito usually lay their eggs in stagnant water.When the eggs remain moist, the eggs hatch into larvae after two or seven days, depending on the weather and surrounding temperature.After a few days,they will become pupa and turn into adult mosquito.
When a mosquito bites someone, they are infected with the dengue virus.Usually,the infected person will get the dengue fever after four to seven days.Then,the mosquito that carries the virus will bite other healthy person and keep spreading the disease.
Finally, prevention to prevent the disease from spreading is to cover the water container and keep the environment clean.
muhammad aqil bin mufek zailani
ReplyDeleteEveryone knows about the dangers of aedes mosquitoes. These mosquitoes can cause deadly dengue fever. Do you know how they breed? They will lay their eggs in stagnant water.
When the eggs hatch in time, larvae will come out of the egg. This larvae live in water and eat small foods such as dead plants and algae. Within five days, the larva will turn into pupae before exchanging into adult mosquitoes
Aedes mosquitoes with no dengue infection will bite people with dengue infections and suck their blood along with the dengue virus.
After the mosquito is finished sucking blood, it will fly while carrying dengue virus in its body. Later, it will bite and suck the blood of a healthy person and then transmit the dengue virus into their body and continue spreading the disease.
So, in order to reduce this disease a few prevention should be taken. For example, by covering the water container or reservoir around the house. For the conclusion, we must keep our environment clean.

ReplyDeleteDengue is one of the major public issue in Malaysia. It is first reported in Penang in 1901 and since then the disease has become endemic through out the country. More than 130,000 cases of dengue had been reported in 2019,making it the highest number of dengue cases recorded in four years.
It all started when Aedes mosquito that carries the virus lays egg on stagnant water. The eggs then will turn into larvae before becoming into a mosquito. Male mosquitoes live by feeding on flower nectar. The one that's spreading the virus by biting people is the females. It sucks human's blood to live. People that's bitten by the virus carrier will be infected. There is no specific medicine to cure this disease. Thus, infected by dengue may cause death to a person.
Despite all this, there is still people that doesn't take any necessary action to prevent it. There's many way for us to prevent this disease from spreading.
First, we must prevent it's population from increasing. Mosquitoes lay their eggs on stagnant water like water inside buckets, discarded tyres and other artificial containers that holds stagnant water. Thus, we must always discard waters that has potential to become one of the breeding spot or cover the container so the mosquito couldn't lay their eggs in there. Next, ensure the environment of your house is clean. Spend some time on the weekend to clean your house. It's very important to keep your environment clean to make sure things like tin cans and plastic bottles that can hold waters are disposed.
In conclusion, we must all take part in preventing this disease from spreading. I hope many people will be aware if this issue and take it seriously.
Selamat Hari Raya to everyone. Thank you for all the comments. We will resume this blog based on the announcement from the management of MRSM Gerik. If the Principal / TPPA asked the teachers to continue the online assignments, then we will continue using this blog. Thank you.
