The image shows cross-cutting relationships. B, W, E, and K represent rock layers, and Q represents a fault. Cross-cutting relationships. Horizontal rock layers B, W, E, and K from bottom to top. Fault line Q divides layers B, W, and E. The layers to the right of the fault have shifted up, with layer E smaller on the right than on the left. Which statement describes the geologic features? Layer K is the oldest. Layer W is the youngest. Fault Q occurred before layer K was deposited. Layers B, W, and E were deposited after fault Q occurred.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
