This question has two parts. First, answer Part A. Then, answer Part B.

Part A.

Viruses have similarities and differences from cells. Which statements below correctly describe either commonalities or differences between them?

• A. Viruses and cells both have a form of genetic material, such as DNA.

• B. Viruses and cells both have organelles which perform basic functions.

• C. Viruses cannot carry out their life cycles unless inside a host cell.

• D. Viruses and cells both have surface proteins which allow for recognition and binding to hosts.

• E. Viruses and cells both have identical life cycles.

Consider the correct answers you chose in Part A. What is the best justification for choosing these two answers?

• Surface proteins on both cells and viruses allow for recognition of the host cells.

• Organelles have distinct functions inside of cells.

• Cells have genetic material and organelles, while viruses have genetic material but do not have organelles.

• Genetic material is essential for living things.

Enzymes are important substances in your body that help bring about specific biochemical reactions. Which of the following are true of enzymes? Select TWO correct answers.

• A. Enzymes help speed up chemical reactions in our bodies.

• B. Enzymes include amylase, which helps break down carbohydrates, and protease, which helps break down proteins.

• C. Enzymes are only used once by the body and are not considered recyclable.

• D. Enzymes are catalysts that raise the activation energy needed to start a reaction.

• E. Enzymes are considered lipids because they have fatty acids.
