Biology

1. What is the building block of RNA?

Correct answer: B

Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.

2. Which division of the nervous system is responsible for the "fight or flight" response, preparing the body to respond to stressful situations?

Correct answer: b

Rationale: The correct answer is B: Autonomic nervous system. The autonomic nervous system controls involuntary bodily functions, including the 'fight or flight' response. This response is crucial for survival, triggering the body to prepare for action in stressful situations by increasing heart rate, dilating pupils, and releasing adrenaline. The somatic nervous system (A) controls voluntary movements, the peripheral nervous system (C) connects the central nervous system to the rest of the body, and the central nervous system (D) consists of the brain and spinal cord, overseeing all bodily functions but not directly involved in the 'fight or flight' response.

3. The muscular tube that transports sperm from the testes to the urethra is called the:

Correct answer: B

Rationale: The correct answer is B: Vas deferens. The vas deferens is a muscular tube that carries sperm from the testes to the urethra. It is an essential part of the male reproductive system, allowing for the transport of sperm for ejaculation. The epididymis is a coiled tube where sperm mature and are stored, not where they are transported to the urethra. The seminal vesicle and Cowper's gland are accessory glands that contribute fluids to semen but are not part of the direct pathway for sperm transport.

4. Where should a semicolon be placed in the following sentence? "He loves reading comics, playing video games, and spending time with friends"?

Correct answer: B

Rationale: Semicolons can join three or more items in a list, especially when the items themselves contain commas. Option (b) is the correct placement.

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

Correct answer: B

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

6. Which of the following is NOT a function of the muscular system?

Correct answer: D

Rationale: The correct answer is D: "Regulating blood sugar levels." The muscular system primarily functions in movement, maintaining posture, and generating heat. Muscles contract and relax to allow movement and help us stay upright. They also produce heat through muscle contractions to maintain body temperature. Regulating blood sugar levels is primarily controlled by the endocrine system, specifically the pancreas and hormones like insulin and glucagon. Therefore, this function is not directly related to the muscular system.
