Part A Consider the temperature effect in the sex determination of a turtle species represented in the graph below. 100 What effect would a decrease in temperature below the epivotal temperature have on sex ratios of these turtles? 50 Тр Temperature FT MT No difference in the proportion of females to males will result as only colder temperatures will alter the sex ratio in the offspring. None of the other answers is correct. Fewer males and females will result. O More males than females will result. More females than males will result. Percent female

The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes?* nd 2 chool The proportion of DDT-resistant mosquitoes in a population remains constant due to O the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest. Over the next year, the finches show a death rate of…
Imagine we identify a gene that is directlyresponsible for the effects of vasopressin on male mammals, includinghumans—we will call it trust1—that leads to the productionof a vasopressin receptor in the brain, which we will callTRUST1. There are different versions of trust1, all of which lead todifferent levels of the behavior associated with this neuropeptideon male behavior. Give some examples where it would be a goodidea to know a particular male’s genotype—that is, which of thetrust1 genes he has. Give an example of when you think science hasgone too far and this information should not be known
