1. Which of the following nutrients is essential for muscle growth and repair?

Correct answer: B

Rationale: Protein is essential for muscle growth and repair as it provides the necessary building blocks (amino acids) for muscle tissue synthesis and repair. While vitamins and minerals are crucial for overall health, protein has a specific role in muscle development. Carbohydrates supply energy for workouts, and fats are important for general health but are less directly involved in muscle growth and repair compared to protein.

2. What is the scientific term for inflammation of the bronchi, often associated with a cough and mucus production?

Correct answer: B

Rationale: Bronchitis is the correct answer. It is the inflammation of the bronchi, which are the air passages in the lungs. Bronchitis typically presents with symptoms such as a persistent cough, mucus production, and sometimes difficulty breathing. Pneumonia, on the other hand, is an infection that causes inflammation in the air sacs of the lungs, not specifically the bronchi. Emphysema is a chronic lung condition characterized by the gradual destruction of the air sacs in the lungs, resulting in breathing difficulties. Pleurisy refers to inflammation of the pleura, the lining around the lungs and chest cavity, causing chest pain when breathing or coughing.

3. Which functional group is commonly found in ketones?

Correct answer: B

Rationale: Ketones contain a carbonyl functional group, which consists of a carbon atom double-bonded to an oxygen atom. This distinguishes ketones from other functional groups such as hydroxyl, ester, and amine. The presence of the carbonyl group, not hydroxyl (choice A), ester (choice C), or amine (choice D), is characteristic of ketones, making choice B, 'Carbonyl', the correct answer.

4. Which of the following nucleic acids carries the genetic information copied from DNA to the ribosomes?

Correct answer: B

Rationale: The correct answer is B: mRNA. Messenger RNA (mRNA) is responsible for carrying the genetic information copied from DNA to the ribosomes for protein synthesis. mRNA serves as a temporary copy of the genetic instructions stored in DNA and acts as a messenger between the nucleus and ribosomes in the cytoplasm where protein synthesis occurs. While rRNA (ribosomal RNA) and tRNA (transfer RNA) play essential roles in the process of translation at the ribosomes, mRNA is the nucleic acid directly involved in carrying the genetic code for protein synthesis. Therefore, choices A, C, and D are incorrect as DNA is the original genetic material, rRNA is a component of the ribosomes, and tRNA carries amino acids during protein synthesis, respectively.

5. What is the structure that connects the ovary to the uterus in the female reproductive system?

Correct answer: B

Rationale: The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes serve as a pathway for the egg to travel from the ovary to the uterus, where fertilization typically occurs. Options (A) Urethra, (C) Vagina, and (D) Cervix are not the structures responsible for connecting the ovary to the uterus, making them incorrect choices for this question.
