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. Identify the interrogative sentence in the following options:

Correct answer: B

Rationale: An interrogative sentence asks a question and typically ends with a question mark.

3. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?

Correct answer: C

Rationale: While Newton's third law states that for every action, there is an equal and opposite reaction, the unbalanced force acting on each object depends on their respective masses. The larger mass of the table (compared to the book) experiences a smaller acceleration, making its movement almost imperceptible.

4. Which part of the spinal cord is responsible for transmitting sensory information from the body to the brain?

Correct answer: a

Rationale: The correct answer is A: Dorsal root. The dorsal root of the spinal cord is responsible for transmitting sensory information from the body to the brain. This root contains sensory nerve fibers that carry information such as touch, temperature, and pain signals from the peripheral nervous system to the central nervous system. Ventral roots, on the other hand, are responsible for transmitting motor information from the brain to the muscles. Gray matter is primarily composed of nerve cell bodies and is involved in processing information, while white matter consists of myelinated nerve fibers that facilitate communication between different parts of the nervous system. Therefore, in this context, the dorsal root is the specific structure that handles sensory information transmission.

5. Which sentence uses the word "literally" correctly?

Correct answer: B

Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.

6. The primary function of the strong nuclear force is:

Correct answer: B

Rationale: The strong nuclear force is responsible for binding protons and neutrons within the nucleus. This force is crucial for overcoming the electrostatic repulsion between positively charged protons in the nucleus, holding the nucleus together. Option A is incorrect as it refers to the role of the electromagnetic force in binding electrons in atomic orbitals. Option C describes the electromagnetic force that mediates the attraction between opposite charges, while option D refers to the electromagnetic force mediating the repulsion between like charges. Understanding the primary function of the strong nuclear force helps explain the stability and structure of atomic nuclei.
