Accepted Answer

An explanation for a very general class of phenomena supported by a wide body of evidence.

Question 5

What is the main difference between a hypothesis and a prediction in scientific research?

Accepted Answer

Question 9

Which of the following is a requirement for natural selection to occur in a population?

Accepted Answer

Individuals must vary in characteristics that are heritable.

Question 10

Which of the following best describes the relationship between evolution and natural selection?

Accepted Answer

Natural selection is a mechanism by which evolution occurs.
