1. What is true about caloric intake for the average person?

Correct answer: C

Rationale: Caloric intake for the average person typically declines with age due to factors such as changes in metabolism, muscle mass, and physical activity levels. As people age, their metabolism tends to slow down, and they may also experience a decrease in muscle mass and physical activity, leading to a reduced need for calories. Option A is incorrect because caloric intake generally decreases rather than increases with age. Option B is incorrect as it suggests a fluctuation in caloric intake that is not typically seen. Option D is incorrect as caloric needs usually change over a person's lifetime due to various factors.

2. Which mineral supports the function of the thyroid?

Correct answer: B

Rationale: Iodine is the mineral that supports the function of the thyroid. The thyroid gland requires iodine to produce thyroid hormones, which are essential for regulating metabolism and other important bodily functions. A deficiency in iodine can lead to thyroid disorders such as hypothyroidism or goiter. Manganese (Choice A), Phosphorus (Choice C), and Zinc (Choice D) do not play a direct role in supporting the thyroid function like iodine does. While these minerals are important for various bodily functions, they are not specifically required for the thyroid gland's hormone production.

3. Which part of the brain is responsible for processing sensory information?

Correct answer: B

Rationale: The parietal lobe of the brain is responsible for processing sensory information such as touch, temperature, and pain. It integrates sensory information from various parts of the body, allowing an individual to perceive and respond to different stimuli. Functions like spatial awareness and perception of the body's position in space are also associated with the parietal lobe. The frontal lobe is responsible for functions like decision-making and personality. The occipital lobe is primarily involved in visual processing, and the temporal lobe plays a role in memory and auditory processing.

4. Which organ is responsible for the production of insulin?

Correct answer: C

Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing insulin, a hormone that regulates blood glucose levels by facilitating the uptake of glucose into cells. Insulin is crucial for maintaining proper blood sugar levels and is produced by specialized cells within the pancreas known as beta cells. Choices A, B, and D are incorrect because the thyroid gland, pituitary gland, and adrenal gland do not produce insulin. The thyroid gland produces hormones that regulate metabolism, the pituitary gland releases various hormones that control other glands, and the adrenal gland produces hormones like cortisol and adrenaline.

5. What is the primary function of the alveoli in the lungs?

Correct answer: B

Rationale: The primary function of the alveoli in the lungs is to exchange oxygen and carbon dioxide. The alveoli are tiny air sacs in the lungs responsible for this gas exchange during breathing. Oxygen diffuses from the inhaled air into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled out of the body. Choice A is incorrect because the alveoli primarily facilitate the exchange of gases, not just the removal of carbon dioxide. Choice C is incorrect as the alveoli do not transport oxygen to the bloodstream but rather facilitate the exchange of gases. Choice D is incorrect as the alveoli are not involved in filtering blood but in gas exchange to ensure proper oxygenation and removal of carbon dioxide in the respiratory process.
