1. Which of the following is NOT one of the major types of bones in the human body?

Correct answer: A

Rationale: The correct answer is A: 'Dense bone'. Dense bone is not a classification of bone types in the human body. The major types of bones include long, short, flat, and irregular bones. Long bones, like the femur, are characterized by being longer than they are wide. Short bones, such as those in the wrist (carpals) and ankle (tarsals), are generally cube-shaped. Flat bones, like the skull or scapula, are thin and provide protection. Irregular bones, such as the vertebrae, have complex shapes that do not fit into the other categories.

2. Muscle soreness after exercise is often caused by microscopic tears in muscle fibers. This is called

Correct answer: C

Rationale: Muscle soreness after exercise is often caused by microscopic tears in muscle fibers, leading to Delayed Onset Muscle Soreness (DOMS). Atrophy refers to the wasting away of muscle tissue, hypertrophy is the increase in muscle size, and spasm is an involuntary contraction of a muscle. DOMS typically occurs 24 to 72 hours after intense exercise and is characterized by muscle stiffness, tenderness, and reduced range of motion. It is a normal response to unfamiliar or strenuous physical activity and indicates that the muscles are adapting to the workload. Therefore, the correct answer is C (DOMS) as it specifically describes the phenomenon of muscle soreness resulting from microscopic tears in muscle fibers, distinguishing it from the other choices which refer to different physiological processes or conditions.

3. How is power related to energy?

Correct answer: B

Rationale: Energy is the capacity to do work, while power is the rate at which work is done or energy is transferred. Power is the amount of energy transferred or converted per unit time. Therefore, energy is related to power as the rate at which work is done. Choice A is incorrect because power and energy are not the same; they are related concepts but represent different aspects. Choice C is incorrect because power does not refer to stored energy but rather the rate of energy transfer. Choice D is incorrect because energy is not the rate at which power is transferred, but the capacity to do work or cause change.

4. If a doctor diagnoses a patient with an impaired posterior pituitary gland, which of the following symptoms related to kidney function does the patient display?

Correct answer: D

Rationale: When the posterior pituitary gland is impaired, there is decreased secretion of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water reabsorption by the kidneys. A deficiency of ADH leads to the inability of the kidneys to concentrate urine, resulting in the production of dilute urine. Therefore, 'Concentrated urine' is the correct symptom associated with impaired posterior pituitary gland. Choices A, B, and C are incorrect. Thirst is more commonly associated with diabetes insipidus, tiredness could be a general symptom but not specifically related to kidney function, and weight gain is not a typical symptom of impaired posterior pituitary gland affecting kidney function.

5. Which enzyme found in saliva is responsible for breaking down carbohydrates into smaller molecules like sugars?

Correct answer: B

Rationale: The correct answer is B. Saliva contains an enzyme called amylase, which specifically targets carbohydrates and breaks them down into smaller molecules like sugars. Pepsin, choice A, is an enzyme found in the stomach that breaks down proteins, not carbohydrates. Lipase, choice C, is responsible for breaking down fats, not carbohydrates. Trypsin, choice D, is an enzyme that breaks down proteins in the small intestine, not carbohydrates. Therefore, choices A, C, and D are incorrect for this question.
