Answer to Question 1

 There are more offspring produced than will actually survive to reach a reproductive age.
 There is genetic variation in all organisms.
 Some traits enhance the chance of survival in an environment. These traits are considered to be favorable.
 Organisms with favorable traits in an environment are more likely to survive and produce offspring. Thus, they are more likely to pass these favorable traits down to the next generation.
 When a particular trait is passed down in large numbers due to natural selection in an environment, it is selected for. It contributes to the success of an organism.

Answer to Question 2

C

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
