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. Usually I take a walk every day after breakfast, ____________ it was raining today.

• A. While
• B. Because
• C. But
• D. When

Correct answer: C

Rationale: The correct answer is 'But.' In this sentence, the conjunction 'but' is used to show a contrast between the usual routine of taking a walk after breakfast and the fact that it was raining today. 'While' suggests a concurrent action, 'Because' implies causation, and 'When' introduces a time relationship, none of which are suitable in this context.

3. Which of the following functions would be most affected by laryngeal damage?

• A. Blinking
• B. Walking
• C. Singing
• D. Hearing

Correct answer: C

Rationale: Laryngeal damage would most affect the function of singing. The larynx, or voice box, houses the vocal cords responsible for producing sound during singing. Damage to the larynx can impair the ability to phonate and control pitch, tone, and quality of the voice, which are crucial for singing. Choices A, B, and D are unrelated to the larynx. Blinking is controlled by the facial nerve, walking involves motor functions and coordination, and hearing is related to the ear structures and auditory nerves.

4. What does cytokinesis refer to?

• A. Division of the nucleus
• B. Division of the cytoplasm
• C. Separation of chromosomes
• D. Formation of spindle fibers

Correct answer: B

Rationale: Cytokinesis refers to the division of the cytoplasm of a parental cell between two daughter cells during cell division. It ensures that each daughter cell receives its share of organelles and cytoplasmic components necessary for cellular functions. Choice A, division of the nucleus, is incorrect as this process is known as mitosis. Choice C, separation of chromosomes, is incorrect as it refers to the process of chromatid separation during mitosis. Choice D, formation of spindle fibers, is incorrect as spindle fibers are involved in mitosis to separate chromosomes, not in cytokinesis.

5. What is the median of Pernell's scores (81, 92, 87, 89, and 94)?

• A. 87
• B. 89
• C. 92
• D. 94

Correct answer: B

Rationale: To find the median, we first need to arrange the scores in ascending order: 81, 87, 89, 92, 94. Since there are five scores, the middle score would be the third one, which is 89. Hence, the median of Pernell's scores is 89. Choice A (87) is incorrect because it is the second score in the ordered list, not the middle one. Choice C (92) and Choice D (94) are also incorrect as they are not positioned in the middle of the ordered series.
