In this passage, which of the following is not mentioned as a role of HGH in the human body?

Correct Answer: C

Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.

Correct Answer: D

Rationale: The passage does not suggest that super foods are more expensive than processed foods.

Correct Answer: D

Rationale: The passage does not mention the divisions that make up the current CDC.

Correct Answer: C

Rationale: Elasticity, as used in the passage about Hypertension, refers to the stretchiness or flexibility of blood vessels. The text mentions that blood vessels lose elasticity and stiffen as a person ages, indicating that they become less flexible. This eliminates choices A and D (Firmness and Rigidity) as the correct answers. Choice B (Compactness) is unrelated to the concept of elasticity in the context of blood vessels and is therefore incorrect. Understanding elasticity as the ability to stretch or flex helps in choosing flexibility as the correct answer.

Correct Answer: B

Rationale: Satiety refers to a state of being satisfied, particularly in terms of appetite. In the context of the excerpt provided, it explains that individuals who lack adequate sleep may experience lowered levels of leptin, a hormone that controls appetite. As a result, even after meeting their caloric needs, they may still crave carbohydrates, indicating a lack of satisfaction or satiety. This can lead to obesity and disrupt healthy eating habits. Therefore, choice B, 'A state of being satisfied,' is the correct answer. Choices A, C, and D are incorrect as they do not accurately reflect the meaning of satiety in the context of appetite regulation and sleep's impact on food cravings.

Correct Answer: A
