b. Hypotheses are guesses; theories are correct answers.

c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power.

Answer 1

1. The primary “red flag” one should look for is whether the source might have a reason or interest in making a statement that aligns with one side or another in your story.

2. Descent with modification refers to the passing on of traits from parent organisms to their offspring. This passing on of traits is known as heredity, and the basic unit of heredity is the gene. Genes hold information about every conceivable aspect of an organism: its growth, development, behavior, appearance, physiology, reproduction. Genes are the blueprints for an organism and these blueprints are passed from parents to their offspring each generation.
