Answer:
The first question is answer A. The question asks for the independent variable, meaning this variable doesn't depend on any other variable. B is the dependent variable because the life span depends on the vitamin.
The second answer is A, the control group. It cannot be the other groups because they aren't real groups. Independent and dependent are variables, not groups.
Answer: Basic Principles of Gas Exchange
