Summary Introduction
To describe:
An evolutionary trend (in either rabbit or virus) that might occur after a rabbit population first encounters the Myxoma virus.
Introduction:
Myxoma virus is a virus that infects rabbits. It causes myxomatosis in rabbits. This virus was used as a pest control in Australian subcontinent. This virus is very much effective against the host that is it can very easily evade the immune mechanism of hares and rabbits. It causes localized benign fibromas in rabbits and hares.

Discussion Thread :
Ever wondered why mosquitoes exist? Everyone knows they serve as vectors for many illnesses (malaria, yellow fever and dengue fever to name a few)....but do they serve any "useful" purpose?
Yes, they do!

Please comment on one surprising fact you learned from this article and explain in a few sentences.
1. Ebola virus, a dangerous outbreak was found to have occurred due to possible transmission of virus from bats and the contact of contaminated bodily fluids such as blood, urine, etc. Therefore, such a devastating disease outbreak around the world which initially broke in West Africa that along with acute poverty went through lack of proper healthcare, transportation, communication and resources, made it difficult for public health in bringing a quicker solution against it, hence spreading faster. I think to prevent similar pandemics in the future, countries especially with low economies should be prepared with potential resources to combat a health emergency. Moreover, international countries should intervene by investing in African healthcare systems, especially in places suffering from extreme poverty, to build stronger and accessible health care that provides treatment for its residents (Matua et al., 2015). Local Public health officials should visit certain vulnerable places and…

- Discuss Concepts Many city-dwellers have noted that the density of cockroaches in apartment kitchens appears to vary with the habits of the occupants: people who wrap food carefully and clean their kitchen frequently tend to have fewer arthropod roommates than those who leave food on kitchen counters and clean less often. Interpret these observations from the viewpoint of a population ecologist.arrow_forwardQUESTION S Which of the following viruses is the most frightening as a cause of a global pandemic because it is impossible to predict when the next pandemic will occur or how severe it will be?

Many lobstermen in New York and Connecticut lost small businesses that their families had owned for generations. Some believe the die-off followed heavier sprays of pesticides to control mosquitoes that carry the West Nile virus. Explain why a chemical substance that targets mosquitoes might also harm lobsters but not fish.arrow_forward
- 3. In this problem you will create, and then consider, a model for the effect of influenza and pneumonia on the population of large US cities over a two-year-period. (a) The figure below is taken from [5]. Sketch on the figure, or on some axes drawn on your own page, a smooth curve that describes the “average behaviour” of the two curves shown in the figure. (b) Based on your sketch in part (a), or otherwise, make a model of the death rate due to influenza and pneumonia in large cities in the USA for the two-year-period beginning 3 August 1934. Your model should be in the form of a function. In making your model, you may have to make assumptions and/or choices. Briefly justify each assumption and choice.arrow_forwardWhich condition is the basis for a species to be re productively isolated from other members?

- 2. According to the recent malaria report of the Department of Health, Disease and Prevention Bureau (2022), there are 4, 251 confirmed cases of malaria in the Philippines and majority of the cases are due to Plasmodium falciparum. P. falciparum life cycle includes gametocytes that will aid the parasite to reproduce sexually in its anopheline vectors. Examine Figure 2 below. Provide three (3) qualitative descriptions of the P. falciparum gametocyte. Write your answers in a complete sentence. Fig. 2. Plasmodium falciparum gametocyte in thin blood smear (CDC, 2022)arrow_forwardQ5. Which of the following is FALSE? If a genetic disease reduces fertility and the allele that causes the disease offers no other advantage, the allele will likely eventually disappear, due to natural selection. Natural selection does not favor individuals who are homozygous for the sickle-cell allele, because these individuals typically die before they are old enough to reproduce. Individuals who are heterozygous HbA/HbS are protected from malaria, and this is why sickle-cell anemia persists in wetter, mosquito-prone regions in Africa. O In regions where malaria does not occur, individuals who are heterozygous HbA/HbS have a selective advantage over those who are homozygous for the normal hemoglobin allele (HbA).arrow_forwardO e.
