1. What is the role of the pancreas in regulating blood sugar levels?

Correct answer: B

Rationale: The correct answer is B. The pancreas plays a crucial role in regulating blood sugar levels by producing both insulin and glucagon. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, while glucagon raises blood sugar levels by stimulating the release of stored glucose into the bloodstream. Choice A is incorrect because the pancreas produces both insulin and glucagon. Choice C is incorrect because the pancreas does not store glucose; instead, it regulates glucose levels. Choice D is incorrect because adrenaline is produced by the adrenal glands, not the pancreas, and is not directly involved in regulating blood sugar levels.

2. What is the sensory threshold?

Correct answer: A

Rationale: The sensory threshold refers to the smallest amount of stimulus required for an individual to perceive or feel a sensation. It is the minimum level of stimulus intensity that is detectable by an individual. Choice B is incorrect because the sensory threshold is not specifically related to feeling pain but rather to perceiving any sensation. Choice C is incorrect as the sensory threshold is about perception and not necessarily physical reaction. Choice D is incorrect as it describes the source of the stimulus, not the threshold for perception.

3. What is the scientific term for scar tissue?

Correct answer: B

Rationale: The correct scientific term for scar tissue is fibrous connective tissue. Scar tissue is primarily composed of fibrous connective tissue, which forms as part of the body's natural healing process in response to injury or trauma. Epithelial tissue, cartilage, and adipose tissue are not typically involved in scar formation. Therefore, the correct answer is fibrous connective tissue, as it is the specific type of tissue that makes up scar tissue.

4. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

Correct answer: D

Rationale: The correct answer is 'Fever.' Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing, difficulty breathing, and chest tightness due to inflammation and narrowing of the airways. Fever is more commonly seen in conditions such as infections or inflammatory diseases rather than asthma. Choices A, B, and C are common symptoms of asthma and are related to the constriction and inflammation of the airways, leading to breathing difficulties and chest discomfort.

5. Which gland produces the hormone responsible for regulating blood sugar levels?

Correct answer: C

Rationale: The correct answer is the pancreas. The hormone responsible for regulating blood sugar levels is insulin, which is produced by the pancreas. The pituitary gland produces various hormones that regulate other endocrine glands, the thyroid gland produces hormones that regulate metabolism, and the adrenal glands produce hormones involved in the stress response. Therefore, choices A, B, and D are incorrect in the context of regulating blood sugar levels.
