235 B Points Cystic Nibrosis results from a small change or (1) ◻ In the substance that makes up the chromosomes known as C ◻ The change occurred in the sima" unit of herredity or (क) ◻ encoding a protein called the CFTR. The CFTR is a pore known as a (4) channel protein q, which enables chloribe to cross the slama membrane. Claride uses these ports to move down the the concentration ◻ yadient by the process of is ◻ However, in cystic: fibrois, the CFTR is not inserted into the plama membrane. Instead it is degraded by seult, barrel-shaped organelles called (7) ◻ The lack of CFTits in the planma membrane decreanes the movement of chloride into sweat gland cells. Normally, sodium followi chloride into sweat gland celly. So, in CF, sodium and water remain in the sweat gland and are secreted onto the shin surface, reulting in sweat that is saltier than usual. In the lungs, the lock of the CFTR impedes water movement across plasma membranes into the lung parsageways.a process called [8] ◻ Without adecuate water, thick ropy mucus can block passageways.

This problem is not for credit since we will not cover this material until the last (or second-last) class. This material may appear on the final exam. a. The graph $G_1$ is a planar connected graph. It has 19 edges, and 7 faces. How many vertices does $G_1$ have? Answer: b. True or false: if $G_2$ is a connected graph with 6 edges, 14 faces, and 6 vertices, then $G_2$ is planar. True False c. True or false: There is a regular convex polyhedron with triangular faces and with all vertices of degree 5. True False d. Suppose the graph is planar but not connected, and has 5 components. Derive a variant of Euler's formula for this case. v-e+f=

1. Near the equator, the Sun is approximately straight overhead at noon, and around 1000 W/m² solar irradiance reaches Earth. Around this time of day, assuming ambient temperature of 40°C, and a 10m x 10m x 2m-tall greenhouse with ½"-thick glass walls that reflect away 20% of the incoming sunlight, and only thinking of conductive losses, estimate the maximum temperature reached in the interior of the greenhouse. Hint: when are losses and sources balanced?
