1. Which of the following describes the event of ovulation?

Correct answer: C

Rationale: Ovulation is the release of a mature egg (ovum) from the Graafian follicle in the ovary. This process is essential for fertilization. Choice A is incorrect because the fallopian tube does not move the ovum to the uterus; rather, it provides a pathway for the egg to travel from the ovary to the uterus. Choice B is incorrect as the oocyte undergoes its first meiotic division after ovulation. Choice D is incorrect because the corpus luteum forms after ovulation and is responsible for producing progesterone.

2. The activities of an anatomist consist of ______, whereas those of a physiologist consist of _____.

Correct answer: A

Rationale: An anatomist focuses on observing the structure and morphology of body parts, such as organs, tissues, and cells, to understand their organization. On the other hand, a physiologist is more concerned with studying the functions and processes of these body parts, including how they work individually and together to maintain homeostasis. Therefore, the correct answer is 'observing body parts; studying functions of body parts.' Choices B, C, and D are incorrect as they do not accurately reflect the primary activities of anatomists and physiologists.

3. Is the parietal pleura a visceral membrane?

Correct answer: B

Rationale: The statement that the parietal pleura is a visceral membrane is false. The parietal pleura is actually a membrane that lines the thoracic cavity and is responsible for protecting and cushioning the lungs. Visceral pleura, on the other hand, is the membrane that covers the surface of the lungs. Therefore, the parietal pleura is not a visceral membrane, making the correct answer 'False.' Choices C and D are not relevant as the question is asking for a true/false statement.

4. What is homeostasis?

Correct answer: D

Rationale: The correct answer is D: Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. Choices A, B, and C are incorrect. Choice A describes obesity, choice B describes a specific scenario with room temperature, and choice C refers to overeating, which is not related to homeostasis.

5. When does cell death first occur?

Correct answer: D

Rationale: Cell death, also known as apoptosis, first occurs during fetal development when specific cells are programmed to die. This process is essential for shaping and organizing tissues and organs. Choices A, B, and C are incorrect because cell death begins much earlier, during fetal development, rather than later in life or at puberty. Understanding the timing of cell death in different stages of life is crucial in developmental biology.
