1. What is the scientific name for the kneecap?

• A. Patella
• B. Femur
• C. Tibia
• D. Fibula

Correct answer: A

Rationale: The correct answer is A: Patella. The patella is the scientific term for the kneecap, a small, flat, triangular bone situated in front of the knee joint. The femur, tibia, and fibula are also bones in the leg, but they are not synonymous with the kneecap. The femur is the thigh bone, the tibia is the shin bone, and the fibula is the outer lower leg bone. Therefore, the correct term for the kneecap specifically is the patella.

2. What is the final phase of mitosis?

• A. Prophase
• B. Telophase
• C. Anaphase
• D. Metaphase

Correct answer: B

Rationale: Telophase is indeed the final phase of mitosis. During telophase, the chromosomes have reached opposite poles of the cell, the nuclear envelope is re-forming around the separated sister chromatids, and cytokinesis may also occur, leading to the division of the cell into two daughter cells. Choice A, Prophase, is incorrect as it is the initial phase of mitosis where chromatin condenses into chromosomes. Choice C, Anaphase, is incorrect as it is the phase where sister chromatids separate and move towards opposite poles. Choice D, Metaphase, is incorrect as it is the phase where chromosomes align at the cell's equator before separating.

3. What is the role of the pancreas in the digestive system?

• A. To store bile
• B. To secrete digestive enzymes
• C. To digest proteins
• D. To absorb nutrients

Correct answer: B

Rationale: The correct answer is B: 'To secrete digestive enzymes.' The pancreas plays a crucial role in the digestive system by secreting digestive enzymes that aid in breaking down food in the small intestine. These enzymes help in the digestion of carbohydrates, fats, and proteins, facilitating the absorption of nutrients from the digested food. Choice A is incorrect because the pancreas is not responsible for storing bile; the gallbladder stores bile. Choice C is incorrect because the pancreas secretes enzymes for protein digestion but does not digest proteins itself. Choice D is incorrect as the absorption of nutrients primarily occurs in the small intestine, not in the pancreas.

4. Which of the following is NOT a component of the genitourinary system?

• A. The kidneys
• B. The urethra
• C. The rectum
• D. The bladder

Correct answer: C

Rationale: The rectum is part of the digestive system, not the genitourinary system. The genitourinary system comprises organs involved in reproduction and urine formation and excretion, such as the kidneys, urethra, and bladder. Choices A, B, and D are all components of the genitourinary system. The kidneys filter blood and produce urine, the urethra is a tube that carries urine from the bladder out of the body, and the bladder stores urine before it is excreted.

5. What does the term 'dilution' refer to in a solution?

• A. Adding more solvent to decrease concentration
• B. Adding more solute to increase concentration
• C. Reducing the temperature to increase solubility
• D. Increasing pressure to increase solubility

Correct answer: A

Rationale: The term 'dilution' in a solution refers to adding more solvent to decrease the concentration of the solution. Dilution involves reducing the concentration of the solute in the solution by increasing the amount of solvent. Choice B is incorrect because adding more solute would increase the concentration, not decrease it. Choices C and D are also incorrect as they relate to factors affecting solubility, not dilution specifically. Therefore, choice A is the correct answer as it accurately defines the process of dilution in a solution.
