35. A researcher is keeping tabs on a population of butterflies in Southern California. The species being studied is commonly known as Gossamer-Winged butterflies. These butterflies can have copper tipped wings (dominant trait) or blue tipped wings (recessive trait). Butterflies, like many organisms, are sensitive to changes in their habitat. This particular population of butterflies being studied has had significant changes to their habitat in recent years due to drought. In order to keep track of the population, the researcher counts the number of copper versus blue tipped wings in the population every two years and collects DNA samples to keep track of allele frequencies. The chart below represents the data he collected in 2017 (day 1) and 2019 (day 730). (20 pts total) \begin{tabular}{|c|c|c|c|c|} \hline Time (days) & Copper Tip Wings (CC) & Copper Tip Wings (Cc) & Blue Tip Wings (cc) & Total \\ \hline 1 & 190 & 485 & 325 & 1000 \\ \hline 730 & 300 & 515 & 385 & 1200 \\ \hline \end{tabular} Using the data in the chart above you will answer parts a-d. Show all work on the next page. This page is strictly for your final answers: a. Calculate the observed genotypic frequencies at day \( 1 .(3 \mathrm{pts}) \) Write final answer here: b. Calculate the expected genotypic frequencies at day 1 IF the population were in Hardy-Weinberg equilibrium. \( (5 \mathrm{pts}) \) Write final answer here: c. Calculate and compare the observed genotypic frequencies to the expected genotypic frequencies at day 730. Does the population of Gossamer-Winged butterflies seem to be evolving? ( 7 pts) Write final answers below: Observed genotypic frequencies: Expected genotypic frequencies: Null Hypothesis: Observation: d. To add validity to your hypothesis in part (c) complete the Chi Square analysis on the next page. What does this result mean for the Gossamer-Winged butterfly population? ( 5 pts) Write final answer here:

Calculate the following commutators (perform your calculations in coordinate representation): (a) [\hat{x}^2, \hat{p}_x] (2 points); (b) [\hat{x}, \hat{T}] (2 points); (c) [\hat{p}_x^2, V(x)] (2 points). where \hat{T} = -\frac{\hbar^2}{2m}\frac{d^2}{dx^2}, \hat{p}_x = -i\hbar\frac{d}{dx}, V(x) is potential energy (treat it as if it is a function of x).

Problem 2 A closed-loop system with the plant being the dynamic system of Problem 1, and a PID compensator having the transfer function $D_c(s) = \frac{G_1 + G_2s + G_3s^2}{s}$ (a) Determine the transfer function $H(s)$ of the closed-loop system. (b) The \"nominal value\" of the sensor scale factor $c = 1$. For this value of $c$, the parameters $G_1, G_2, G_3$ are to be designed such that the closed loop poles are located at $s = -4, -1 + j, -1 - j$ Determine the values of the parameters $G_1, G_2, G_3$ for which the poles achieve these values.
