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

• A. The fallopian tube moves the ovum to the uterus.
• B. The oocyte undergoes its first meiotic division.
• C. The Graafian follicle releases an ovum.
• D. The corpus luteum produces progesterone.

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. Do chromosomes get longer as a cell ages?

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: Chromosomes do not get longer as a cell ages. In fact, chromosomes condense and become more compact during cell division to ensure proper segregation. Choice A is incorrect because chromosomes do not elongate with age. Choice C is not the correct answer as there is scientific evidence to support that chromosomes do not lengthen over time. Choice D is not the right option as the correct answer is 'False' in this case.

3. What is the membrane on the surface of a lung called?

• A. visceral pleura
• B. parietal pleura
• C. visceral pericardium
• D. parietal pericardium

Correct answer: A

Rationale: The correct answer is A: visceral pleura. The membrane covering the surface of the lungs is called the visceral pleura. It is a serous membrane that is in direct contact with the lung tissue. Choices B, C, and D are incorrect because the parietal pleura covers the inner surface of the chest wall and diaphragm, the visceral pericardium covers the surface of the heart, and the parietal pericardium is the outer layer of the pericardium surrounding the heart, respectively.

4. An individual with which of the following blood type can receive only blood of that same type?

• A. Type O
• B. Type A
• C. Type B
• D. Type AB

Correct answer: A

Rationale: The correct answer is Type O. Individuals with blood type O can only receive blood from donors with blood type O. This is because type O blood lacks both A and B antigens, so if a person with type O blood receives blood with A, B, or AB antigens, their immune system will recognize these as foreign substances and attack them. Choices B, C, and D are incorrect because individuals with type A can receive blood from A or O donors, individuals with type B can receive blood from B or O donors, and individuals with type AB can receive blood from A, B, AB, or O donors.

5. The thoracic cavity lies _____________ the abdominopelvic cavity.

• A. dorsal (posterior) to
• B. ventral (anterior) to
• C. superior to
• D. inferior to

Correct answer: C

Rationale: The correct answer is 'superior to.' The thoracic cavity is located above the abdominopelvic cavity, making it superior. The term 'dorsal (posterior) to' refers to the back side, 'ventral (anterior) to' indicates the front side, and 'inferior to' means below. In the context of body cavities, the thoracic cavity is positioned higher than the abdominopelvic cavity, making 'superior to' the most appropriate choice.
