English Grammar

1. The artist paints breathtaking landscapes. What is the third-person singular, present tense form of the verb "paint"?

Correct answer: B

Rationale: Verbs change depending on the subject (person) and time (tense).

2. What is the process of breaking down proteins into amino acids called?

Correct answer: A

Rationale: Rationale: Proteolysis is the process of breaking down proteins into amino acids. Lipolysis is the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides. In this context, the specific process of breaking down proteins into amino acids is best described by proteolysis.

3. The human body's largest organ, responsible for detoxification and a multitude of other functions, is the:

Correct answer: B

Rationale: The correct answer is B: Liver. The liver is the largest internal organ in the human body and is responsible for detoxification, processing nutrients, producing bile, and regulating blood sugar levels, among other functions. While the heart is vital for pumping blood, the lungs are crucial for respiration, and the skin is the body's largest external organ, the liver plays a central role in detoxification and various metabolic processes, making it the correct answer to this question.

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?

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. 7 is divisible by which of the following numbers?

Correct answer: D

Rationale: Rationale: 1. 7 is divisible by 1 because every number is divisible by 1. 2. 7 is divisible by 7 because any number is divisible by itself. 3. 7 is not divisible by 2 because 7 is an odd number and not divisible by 2. 4. 7 is not divisible by 3 because the sum of the digits of 7 (7) is not divisible by 3. Therefore, 7 is divisible by 1, 7, and itself (7), making the correct answer D) 2, 3, and 7.

6. A 10 kg box rests on a frictionless surface. A horizontal force of 20 N is applied to the box. What is the box's acceleration?

Correct answer: C

Rationale: Use Newton's second law, F = ma, where F is the net force, m is the mass, and a is the acceleration. Since there is no friction, the net force equals the applied force (20 N). Therefore, a = F/m = 20 N / 10 kg ≈ 2 m/s².
