physics

1. Which property of a substance describes its ability to conduct heat or electricity?

Correct answer: d

Rationale: Conductivity refers to a substance's ability to conduct heat or electricity.

2. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?

Correct answer: b

Rationale: The correct answer is B: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands, not the thyroid gland. PTH plays a crucial role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys. This hormone acts in opposition to calcitonin, which is produced by the thyroid gland and works to lower blood calcium levels by promoting calcium deposition into bones. Thyroxine (C) is a thyroid hormone that regulates metabolism, not calcium levels. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels.

3. What is the main reason why elements in Group 18 (Noble gases) are generally unreactive?

Correct answer: C

Rationale: Noble gases have their outermost electron shells filled with 8 electrons, achieving a stable configuration with minimal urge to gain or lose electrons, making them less prone to chemical reactions.

4. The energy absorbed during a chemical reaction is called:

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

5. What is the primary function of the coronary arteries in the cardiovascular system?

Correct answer: A

Rationale: The primary function of the coronary arteries in the cardiovascular system is to carry oxygenated blood to the heart muscle. These arteries supply the heart muscle with the necessary oxygen and nutrients it needs to function properly. Without adequate blood flow through the coronary arteries, the heart muscle can become deprived of oxygen, leading to conditions like angina or even a heart attack. Options B, C, and D are incorrect as they do not accurately describe the function of the coronary arteries. Option B is incorrect because the coronary arteries carry oxygenated blood, not deoxygenated blood. Option C is incorrect because the pulmonary arteries, not the coronary arteries, carry blood to the lungs for oxygenation. Option D is incorrect because the regulation of blood pressure in the systemic circulation is primarily controlled by mechanisms such as the kidneys and the autonomic nervous system, not the coronary arteries.

6. A doctor orders 1 gram of a medication to be administered intravenously. The available vial contains 200 milligrams per milliliter. How many milliliters of the solution should be drawn up?

Correct answer: B

Rationale: First convert grams to milligrams (1 gram * 1000 milligrams/gram = 1000 milligrams). Then, divide the desired dosage by the concentration per milliliter: 1000 milligrams / 200 milligrams/milliliter = 5 milliliters.
