If you don't finish all your pills, you are selecting for the most resistant bacteria. Most mutations: A) are random, meaning that they only occur in small populations. B) are beneficial to the organism in which they occur. C) are random, meaning they are unrelated to how useful or harmful they might be to the organism in which they occur. D) are in response to natural selection. E) migrate from one population to another. Which of the following statements BEST describes the Greenhouse Effect?

13) Answer : C. Random mutation occur which can be harmful or beneficial based on type of mutation and frequency of mutation.

14) Answer : D. Gases in the upper atmosphere absorbs some of the radiations from Sun and some radiated back from the Earth. All the absorbed radiations in the form of heat warms the Earth.

15) Answer : D : Even with drug addiction he could survive upto old age and have 10 children.
