Radio Station Problem: Radio station KROK plans to broadcast rock music to people on the beach near Ocean City (O.C. in Figure 6-5g). Measurements show that Ocean City is 20 miles from KROK, at an angle of 50north of west. KROKs broadcast range is 30 miles. a. Use the law of cosines to calculate how far along the beach to the east of Ocean City people can hear KROK. b. There are two answers to part a. Show that both answers have meaning in the real world. c. KROK plans to broadcast only in an angle between a line from the station through through the point on the beach farthest to the east of Ocean City that people can hear the station. What is the measure of this angle?

Fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology C) Describe the steps in the theory of natural selection a. Overproduction of offspring occurs, variation within those offspring lead to competition, and the best suited variations experience higher reproductive success, so the next generation looks more like those successful variations D) Distinguish between natural and artificial selection a.
