1. What is the term for the division of the cytoplasm?

• A. Cytokinesis
• B. Mitosis
• C. Meiosis
• D. Apoptosis

Correct answer: A

Rationale: Cytokinesis is the correct term for the division of the cytoplasm during cell division. It is the final stage of cell division, following either mitosis or meiosis, where the cytoplasm of a parent cell is divided into two daughter cells. Mitosis is the process of nuclear division, while meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes of the parent cell. Apoptosis, on the other hand, is programmed cell death and not the division of the cytoplasm.

2. What are the components of the female external genitalia and their functions?

• A. Ovaries: internal reproductive organs
• B. Vulva: external structures of the female genitalia
• C. Uterus: internal reproductive organ for fetal development
• D. Vagina: birth canal

Correct answer: B

Rationale: The corrected answer is B: 'Vulva: external structures of the female genitalia.' The vulva includes external structures such as the labia, clitoris, and vaginal opening. These structures play roles in sexual arousal and protection of the internal genital organs. Choices A, C, and D are incorrect because they are internal reproductive organs. The ovaries produce eggs, the uterus houses the developing fetus, and the vagina serves as the birth canal. Hence, they are not components of the female external genitalia.

3. What is the anatomical term for the back of the body? Example: Shoulder blade.

• A. Anterior
• B. Superior
• C. Posterior
• D. Inferior

Correct answer: C

Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

4. During antibiotic use, bacteria can evolve resistance. This is an example of:

• A. Coevolution (two species influencing each other's evolution)
• B. Convergent evolution (unrelated organisms evolving similar traits)
• C. Macroevolution (large-scale evolutionary change)
• D. Artificial selection acting on a natural process

Correct answer: D

Rationale: The process of bacteria evolving resistance to antibiotics due to the selective pressure exerted by the antibiotics is an example of artificial selection (human intervention selecting for certain traits) acting on a natural process (bacterial evolution). Antibiotic use creates a selective pressure that favors the survival and reproduction of bacteria with resistance traits, leading to the evolution of antibiotic-resistant strains. - Coevolution (option A) refers to the influence of two species on each other's evolution, which is not the case in the scenario described in the question. - Convergent evolution (option B) involves unrelated organisms evolving similar traits due to similar environmental pressures, which is not directly applicable to the situation of bacteria evolving resistance to antibiotics. - Macroevolution (option C) refers to large-scale evolutionary changes over long periods, which is not specifically demonstrated in the context of bacteria evolving resistance during antibiotic use.

5. Which of the following anatomical terms is not part of the knee?

• A. Medial collateral ligament
• B. Patella
• C. Lateral malleolus
• D. Lateral meniscus

Correct answer: C

Rationale: The lateral malleolus is a bony prominence on the lateral side of the ankle and is not part of the knee anatomy. The other options - medial collateral ligament, patella, and lateral meniscus - are all structures within the knee joint. The medial collateral ligament is located on the inner side of the knee, the patella is the kneecap, and the lateral meniscus is a cartilage structure within the knee joint. Therefore, the correct answer is C, lateral malleolus.
