Correct Answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

Correct Answer: A

Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.

Correct Answer: A

Rationale: The correct answer is A: high refined carbohydrate intake. High intake of refined carbohydrates, such as sugars and white flour, can lead to elevated triglyceride levels, increasing the risk of cardiovascular disease. Choice B, low soluble fiber intake, is incorrect because soluble fiber actually helps lower triglyceride levels. Choice C, high iron intake, is incorrect as iron intake is not directly linked to raising triglyceride levels. Choice D, low fat intake, is also incorrect as not all fats raise triglyceride levels; it depends on the type of fat consumed.

Correct Answer: B

Rationale: Muscle weakness is a common sign of vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to muscle weakness. Brittle nails (Choice A) are not typically associated with vitamin D deficiency. Night blindness (Choice C) is related to vitamin A deficiency, not vitamin D deficiency. Hair loss (Choice D) can be linked to various factors, but it is not a common sign of vitamin D deficiency.

Correct Answer: C

Rationale: The correct answer is C, Down syndrome. Down syndrome is often associated with short stature and limited mobility, which can contribute to feeding difficulties and obesity. Parkinson's disease (choice A) primarily affects motor function, but it is not typically associated with short stature. Muscular dystrophy (choice B) primarily impacts muscle strength and does not necessarily lead to short stature. Multiple sclerosis (choice D) is a neurological condition affecting the central nervous system and does not directly cause short stature or feeding difficulties as seen in Down syndrome.
