1. What is the study of fungi known as?

• A. Virology
• B. Mycology
• C. Bacteriology
• D. Parasitology

Correct answer: B

Rationale: Mycology is the correct answer. Mycology is the branch of biology that specifically deals with the study of fungi. Fungi constitute a separate kingdom of organisms that include various forms such as yeasts, molds, and mushrooms. Virology (A) is the study of viruses, while Bacteriology (C) focuses on bacteria. Parasitology (D) is the study of parasites, which may include protozoa, helminths, and some fungi, but it is not solely dedicated to fungi.

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 condition is characterized by progressive muscle weakness and wasting?

• A. Muscular dystrophy
• B. Myositis
• C. Fibromyalgia
• D. Carpal tunnel syndrome

Correct answer: A

Rationale: Muscular dystrophy is a genetic disorder characterized by progressive muscle weakness and wasting due to mutations in genes responsible for muscle cells' structure and function. Myositis is an inflammatory muscle disease, fibromyalgia is a chronic pain condition, and carpal tunnel syndrome affects the hand and arm nerves, but none present with the progressive muscle weakness and wasting seen in muscular dystrophy.

4. What is the primary function of red blood cells in the cardiovascular system?

• A. To transport oxygen throughout the body.
• B. To fight infection and disease.
• C. To help regulate blood clotting.
• D. To remove waste products from the body.

Correct answer: A

Rationale: Red blood cells, also known as erythrocytes, play a crucial role in the cardiovascular system by primarily transporting oxygen from the lungs to the body's tissues and organs. This essential function is carried out through the interaction of hemoglobin, a protein within red blood cells, which binds to oxygen in the lungs and releases it in the body's tissues. Choices B, C, and D are incorrect. Red blood cells are not actively involved in fighting infections, regulating blood clotting, or eliminating waste products from the body.

5. When conducting a research study, which of the following is NOT a good reason for using a computer?

• A. A computer can be used to store and sort large quantities of data.
• B. Computers can interface with instruments and record data efficiently.
• C. Using a computer eliminates all subjectivity and potential bias from an experiment.
• D. A computer can perform complex calculations more quickly and accurately than a human can.

Correct answer: C

Rationale: Using a computer does not eliminate all subjectivity and potential bias from an experiment. While computers can assist in data collection and analysis, the design and execution of the research study can still be influenced by subjectivity and bias introduced by researchers. Researchers need to recognize their potential biases and take measures to reduce them throughout the research process. Choice A is correct as computers are valuable for managing large datasets. Choice B is correct as computers can efficiently work with instruments and record data. Choice D is correct as computers excel in performing complex calculations faster and more accurately than humans.
