What do they tell you about the evolutionary time between the branch points?• Which branchings are more ancient and which are more recent?• What would you conclude about these immunodeficiency virus proteases, based on this small analysis?1) 286 individuals were newly diagnosed with Human Immunodeficiency Virus in 2018 in Minnesota. Of these individuals, 76% were male. HIV is an enveloped, ssRNA virus_ Baltimore classification VI. This virus targets CD4+ cells. CD4 refers to a glycoprotein which serves as a co-receptor for T-cells, located on T-helper and T-reg immune cells. a) What part of the HIV virus allows for specificity to CD4+ cells?1) a. Why does the immunity offered by COvid vaccines last only for about 2-3 months maximum (compared to other vaccines)? b. Are vaccines the only or the best treatment for Covid? Do the type of vaccines matter? WIll it help for us (public) to learn in an easily accessible manner the side effects (and the frequency of occurrence) of the Covid vaccine? c. Should it be mandatory for all members of the population to take vaccines, assuming that it is readily available? d. Should there be clinical trails performed by agents (institutions) outside the very drug companies that manufacture them? Currently that option is not is not available readily.
