Anatomy
1. What is the name of the microscopic filtering unit within the kidney responsible for waste removal and blood volume regulation?
- A. Nephron
- B. Ureteric bud
- C. Renal pyramid
- D. Glomerulus
Correct answer: A
Rationale: The correct answer is A: Nephron. The nephron is the functional unit of the kidney responsible for waste removal and blood volume regulation. It consists of the renal corpuscle, including the glomerulus for filtration, and the renal tubule for reabsorption and secretion. The other options, such as the ureteric bud, renal pyramid, and glomerulus, are structures within the kidney but do not specifically refer to the filtering unit responsible for waste removal and blood volume regulation like the nephron does.
2. A scientist observes a new species of plant with unusual leaves. They hypothesize that the leaves help capture more sunlight. Which observation would LEAST support this hypothesis?
- A. The plant grows in shady environments.
- B. The leaves have a large surface area.
- C. The leaves contain high levels of chlorophyll.
- D. The plant has shallow roots.
Correct answer: A
Rationale: If the plant thrives in shade, it suggests the leaves may have adapted for other purposes than maximizing sunlight capture.
3. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?
- A. Insulin
- B. Glucagon
- C. Estrogen
- D. Testosterone
Correct answer: A
Rationale: The correct answer is A: "Insulin." In type 1 diabetes, the main type of hormone deficiency is insulin. Insulin is produced by the pancreas and is crucial for regulating blood sugar levels by helping cells absorb glucose. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas, leading to a deficiency of insulin. This results in uncontrolled high blood sugar levels, which can have serious consequences if not managed properly. Glucagon, estrogen, and testosterone do not play a primary role in the hormone deficiency associated with type 1 diabetes.
4. hich word is most closely associated with the adjective "meticulous"?
- A. careless
- B. precise
- C. indifferent

- B. Petra's historical significance lies in its architectural achievements.
- C. Petra's prosperity was linked to its strategic location on trade routes.
- D. Petra's obscurity remains a mystery despite its rediscovery.
Correct answer: C
