5. In quantum mechanics, the matrices $\sigma_x = \begin{pmatrix} 0 & 1 \\ 1 & 0 \end{pmatrix}$, $\sigma_y = \begin{pmatrix} 0 & i \\ -i & 0 \end{pmatrix}$, and $\sigma_z = \begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix}$ are the Pauli matrices. These matrices are very important for understanding the phenomenon of spin. You have already gotten the eigenvalues and eigenvectors for $\sigma_x$ on Problem 2. Determine the eigenvalues and eigenvectors for both $\sigma_y$ and $\sigma_z$.

Question 14 (1 point) Flukes are divided into the groups Monogenea and Digenea. Monogenea have a posterior holdfast with hooks, clamps, and suckers, while Digenea have suckers but never hooks and clamps. Monogenea have only one host in the life cycle and usually live on gills or skin of fish and amphibians. Digenea have at least two hosts, and are named for having two reproductive states in their life cycle (an adult and intramolluscan phase). Based on this information, the blood fluke Schistosoma would be classified as an endoparasite and Monogenean. an endoparasite and Digenean. an ectoparasite and Digenean. an ectoparasite and Monogenean.

A periodic function $f(t)$ is defined as $f(t) = t^2 + \pi$, $-\pi < t \leq \pi$ $f(t) = f(t + 2\pi)$ i) Sketch the graph of $f(t)$ for $-3\pi \leq t \leq 3\pi$. ii) State whether it is even, odd or neither. iii) Show the Fourier series of $f(t)$ is $= \frac{2\pi^2}{6} + \pi + \sum_{n=1}^{\infty} \frac{4}{n^2}(-1)^n \cos nt.$

6. A.)Briefly describe the primary differences between proteoglycans and glycoproteins. B.) Give two examples of roles played by glycosyltransferases. Sugar nucleotides are typically the substrates rather than the sugar alone. Why? C.) Draw the structure of an N-linked galactose (i.e. as part of a glycoprotein) with a $\beta$-glycosidic linkage. Include the structure of the amino acid side chain and the sugar.
