You are traveling across the Pacific Ocean when you come across a small island, island #1. There is lush vegetation and several species of beetles that vary in the color of their carapace. The colors you find are green, blue, purple, and black. A second island, 200 miles closer to the mainland (island #2), is mostly sand with some palm trees and has a single species of beetle that has a brown carapace. You examine the colored beetles and discover that they are all related and that they are related to the brown species on the second island. Which of the following is the most likely scenario?
Select one: a. The brown beetle migrated to island #1 and gave rise to the colored species on island #2 through adaptive radiation. b. The colored species of beetle on island #1 migrated to island #2 and gave rise to the brown beetle through extinction. c. The brown beetle evolved from the colored beetles on island #1 and then migrated to island #2. d. The brown beetle gave rise to all of the colored beetles on island #2 which then migrated to island #1. e. A beetle of some undetermined color gave rise to the beetles that are brown, green, purple, and black and they then migrated to different islands.

Endergonic reactions in cells do not happen spontaneously, that is, they require an input of energy. Coupling such reactions with exothermic ones, such as the hydrolysis of ATP drives the reaction forward. Certain organisms are able to bypass the need for ATP or a proton motive force by ________.
A. using glucose as a direct source of energy in a process similar to spontaneous combustion B. tightly coupling an endergonic and an exergonic oxidation so the endergonic oxidation can drive the completion of the exergonic one in a process known as electron bifurcation C. circumventing the need for endergonic reactions D. tightly coupling an endergonic and an exergonic reduction so the exergonic reduction can drive the completion of the endergonic one in a process known as electron bifurcation
