1. After a person eats birthday cake, which of the following enzymes is needed to break down the sucrose in the cake?

Correct answer: D

Rationale: Sucrase is the correct enzyme needed to break down sucrose into its component sugars, glucose, and fructose. Lactase is responsible for breaking down lactose, maltase for maltose, and peptidase for proteins; therefore, they are not the enzymes required to digest sucrose specifically. In the context of digesting birthday cake, which contains sucrose, sucrase is the enzyme needed for this particular sugar.

2. The term 'symbiotic relationship' describes an interaction between two organisms where:

Correct answer: D

Rationale: In a symbiotic relationship, both organisms involved benefit from the interaction. This mutually beneficial relationship can take different forms, such as mutualism where both organisms benefit, commensalism where one organism benefits and the other is unaffected, or parasitism where one organism benefits at the expense of the other. In this case, the term 'symbiotic relationship' specifically refers to a scenario where both organisms derive some form of benefit from their interaction. Choices A, B, and C are incorrect because they do not accurately describe a symbiotic relationship. In symbiosis, both organisms benefit, making option D the correct choice.

3. What is the name of the muscle responsible for pumping blood throughout the body?

Correct answer: D

Rationale: The correct answer is D, Cardiac muscle. The cardiac muscle is specifically designed to pump blood throughout the body and is found in the heart. In contrast, the bicep, tricep, and deltoid are skeletal muscles responsible for joint movement, not for pumping blood. The bicep is responsible for elbow flexion, the tricep for elbow extension, and the deltoid for shoulder abduction.

4. What enzyme plays a key role in breaking down carbohydrates in the small intestine?

Correct answer: C

Rationale: Amylase is the enzyme responsible for breaking down carbohydrates in the small intestine. It specifically targets starches and sugars, breaking them down into smaller molecules like maltose and glucose that can be absorbed by the body. Pepsin is an enzyme that breaks down proteins in the stomach, not the small intestine. Lipase is responsible for breaking down fats, not carbohydrates. Trypsin is an enzyme that breaks down proteins in the small intestine, not carbohydrates.

5. Which of these descriptions provides the most detailed and objective support for the claim that drinking and driving is unsafe?

Correct answer: C

Rationale: Congressional written testimony on drinking incidents provides the most detailed and factual data on the subject, making it the most objective support for the claim that drinking and driving is unsafe. Choice A, the dramatized television commercial, may be emotionally impactful but lacks detailed data. Choice B, the Department of Transportation's press release, focuses on enforcement actions rather than detailed information on the dangers. Choice D, the highway bulletin warning of penalties, emphasizes consequences rather than providing detailed support for the claim.
