I am using the Hardy-Weinberg Equlibrium to figure out the answers to the questions. Thank you,Make a rough graph (don’t worry about exact accuracy, only the general trends are important) to visuallyrepresent the data provided. You should focus on seeing the trend. Keep the same scaled axes for all yourgraphs, as the three graphs should line up and match up with each other. Your data (plot) points don’t needto be perfectly accurate (remember, you want to visually show the general trends). LH and FSH go on the top graph, estrogen and progesterone in the middle, and endometrium thickness on the bottom graph. * Make sure you use 2 different colours for FSH/LH and estrogen/progesterone. - Now, refer to the data (and graphs). On what day(s) does the hormone LH surge? Suggest a possible function of LH and how you know this based on the data that you graphed.

- A population of boreal toads has a current size of 100 and time steps are measured in years. If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.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…Using the following diagram, determine the value of the PA and P for this animal compared to the population.
