1. Which word completes the sentence "He was ____ by the unexpected turn of events."

• A. elated (joyful)
• B. bewildered (confused)
• C. vindicated (justified)
• D. apathetic (uninterested)

Correct answer: B

Rationale: "Bewildered" best describes the confusion caused by the unexpected events.

2. Which of the following numbers is NOT divisible by 3?

• A. 105
• B. 141
• C. 273
• D. 810

Correct answer: D

Rationale: Rationale: To determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum of the digits is divisible by 3, then the original number is also divisible by 3. A) 105: 1 + 0 + 5 = 6, which is divisible by 3. Therefore, 105 is divisible by 3. B) 141: 1 + 4 + 1 = 6, which is divisible by 3. Therefore, 141 is divisible by 3. C) 273: 2 + 7 + 3 = 12, which is divisible by 3. Therefore, 273 is divisible by 3. D) 810: 8 + 1 + 0 = 9, which is divisible by 3. Therefore, 810 is divisible by 3. Since all the

3. The process by which an organism adapts to its environment through inherited traits is known as

• A. Acclimatization
• B. Behavioral ecology
• C. Natural selection
• D. Niche partitioning

Correct answer: C

Rationale: Rationale: A) Acclimatization refers to the short-term physiological adjustments an individual organism makes in response to changes in its environment. This process is reversible and does not involve inherited traits. B) Behavioral ecology is the study of how behavior contributes to an organism's survival and reproduction in its environment. While behavior can be influenced by natural selection, it is not the process by which an organism adapts through inherited traits. C) Natural selection is the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to the adaptation of populations to their environments. D) Niche partitioning is the process by which species divide resources to reduce competition within an ecosystem. While this can influence the evolution of species, it is not the process by which an organism adapts through inherited traits.

4. Which hormone, produced by the pineal gland, plays a role in regulating sleep-wake cycles and is often associated with the body's internal circadian rhythm?

• A. Melatonin
• B. Serotonin
• C. Dopamine
• D. Endorphin

Correct answer: a

Rationale: The correct answer is A: Melatonin. Melatonin is a hormone produced by the pineal gland that plays a crucial role in regulating sleep-wake cycles and is closely tied to the body's circadian rhythm. It is often referred to as the 'sleep hormone' because it helps signal to the body when it is time to sleep and wake up. Serotonin (option B) is a neurotransmitter that plays a role in mood regulation and happiness. Dopamine (option C) is involved in reward-motivated behavior and movement. Endorphins (option D) are neuropeptides that act as natural painkillers and contribute to feelings of pleasure. Therefore, Melatonin is the hormone associated with the body's internal circadian rhythm and sleep-wake cycles.

5. A block slides down a frictionless inclined plane. What determines its final velocity at the bottom?

• A. The length of the incline
• B. The angle of the incline
• C. The mass of the block
• D. All of the above

Correct answer: B

Rationale: In the absence of friction, the final velocity depends only on the gravitational potential energy gained, which is determined by the height difference related to the angle of the incline.

6. A bookshelf has triangular shelves with a base of 40cm and a height of 30cm. The depth of the shelf is 25cm. What is the volume of each shelf?

• A. 3000 cu cm
• B. 3750 cu cm
• C. 5000 cu cm
• D. 7500 cu cm

Correct answer: B

Rationale: Calculate the area of the triangle (1/2 * base * height) and multiply by the depth.
