1. What happens to the density of a gas when its temperature increases at constant pressure?

• A. It increases.
• B. It decreases.
• C. It remains the same.
• D. Information insufficient

Correct answer: B

Rationale: As gas particles gain thermal energy with increasing temperature, they spread out, decreasing the density.

2. Fertilization of the egg by sperm typically occurs in the:

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. Fertilization of the egg by sperm typically occurs in the fallopian tube. After ovulation, the egg travels through the fallopian tube where it can meet sperm for fertilization. The fallopian tube provides an ideal environment for fertilization to occur due to its proximity to the ovaries and the uterus. The other options, A: Ovary, C: Uterus, and D: Vagina, are not the typical sites for fertilization to take place. Therefore, the fallopian tube is the most appropriate location for the union of egg and sperm to form a zygote.

3. The Merkel cells, located in the epidermis, are specialized for:

• A. Melanin production
• B. Temperature sensation
• C. Touch perception
• D. Immune defense

Correct answer: C

Rationale: The correct answer is C: 'Touch perception.' Merkel cells, also known as Merkel discs, are found in the skin's epidermal layer and are responsible for sensing touch. These cells are located near nerve endings and help detect light touch and pressure on the skin. They play a crucial role in the perception of tactile sensations and are not involved in melanin production, temperature sensation, or immune defense. Therefore, the specialized function of Merkel cells is primarily related to touch perception, making option C the correct choice.

4. Bradycardia refers to a heart rate that is:

• A. Normal (60-100 bpm)
• B. Slightly elevated (100-120 bpm)
• C. Significantly elevated (>120 bpm)
• D. Abnormally slow (<60 bpm)

Correct answer: D

Rationale: The correct answer is D. Bradycardia refers to an abnormally slow heart rate, typically defined as being less than 60 beats per minute (bpm). A heart rate of 60-100 bpm is considered normal, not bradycardia. Choices B and C incorrectly describe elevated heart rates, which are not characteristic of bradycardia. Therefore, option D is the most accurate description of bradycardia as it signifies a heart rate that is slower than normal.

5. What is the meaning of the idiom "to cross that bridge when we come to it"?

• A. To deal with a problem immediately
• B. To plan for the future in detail
• C. To worry about potential problems prematurely
• D. To avoid difficult situations

Correct answer: C

Rationale: The idiom suggests dealing with challenges as they arise, not before.

6. The beautiful flowers brightened the room. Which word is the adverb form of the adjective "beautiful"?

• A. beautiful
• B. beautifully
• C. beautification
• D. beautify

Correct answer: B

Rationale: Adverbs are formed from adjectives by adding "-ly" (usually).
