Answer to Question 1

In any group of organisms, more offspring are produced than can survive to reproductive age. Random variations occur in all organisms. Some of these traits are inheritable-they can be passed on to offspring. Some inheritable traits make an organism better suited to its environment. Because bearers of favorable traits are more likely to survive, they are also more likely to reproduce successfully than bearers of unfavorable traits. Favorable traits tend to accumulate in the population-they are selected. Unfavorable traits are weeded out by competition.

Answer to Question 2

B
