1. Which of the following organs is responsible for filtering waste from the blood?

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.

2. Which of the following describes the term allele?

Correct answer: B

Rationale: The correct answer is B. Alleles are different forms of a gene that can exist at a specific locus. They represent variations of a gene and are inheritable. Choice A is incorrect as it does not fully capture the concept of an allele, which is a specific form of a gene rather than a substitution. Choice C is incorrect as alleles are not a grouping of various genes but rather different forms of a single gene at a specific locus. Choice D is also incorrect as it does not accurately describe alleles; alleles are variations of genes, not base pairs.

3. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

Correct answer: C

Rationale: Cardiac muscle is the type of muscle tissue found in the heart. Unlike skeletal muscle and smooth muscle, cardiac muscle is striated and involuntary, meaning it contracts without conscious control. It forms the majority of the heart's structure and is essential for its rhythmic contraction to pump blood throughout the body. Skeletal muscle is attached to bones and responsible for voluntary movements, while smooth muscle is found in organs and blood vessels, controlling various involuntary functions like digestion and blood flow. Therefore, choices A (Skeletal muscle) and B (Smooth muscle) are incorrect as they are not the types of muscle tissue found in the heart.

4. Which term refers to the condition where a muscle shortens in length while generating force, leading to movement at a joint?

Correct answer: D

Rationale: Concentric contraction refers to the condition where a muscle shortens in length while generating force, leading to movement at a joint. This type of contraction is commonly associated with the lifting phase of an exercise where the muscle is actively shortening against resistance. Isometric contraction (Choice A) involves muscle contraction without a change in muscle length, Eccentric contraction (Choice B) involves the muscle lengthening while generating force, and Isotonic contraction (Choice C) refers to muscle contraction against a constant load with a change in muscle length.

5. Which of the following is NOT a function of the nervous system?

Correct answer: C

Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.
