1. What is the function of ribosomal RNA (rRNA)?

• A. Carries amino acids to the ribosomes
• B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
• C. Forms the structural framework of ribosomes
• D. Controls the rate of protein synthesis

Correct answer: C

Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.

2. Which of the following is NOT a part of a plant cell?

• A. Cell wall
• B. Plasma membrane
• C. Vacuole
• D. Mitochondria

Correct answer: D

Rationale: Rationale: A) Cell wall: This is a structure found in plant cells that provides support and protection. B) Plasma membrane: Also known as the cell membrane, it surrounds the cell and regulates the passage of substances in and out of the cell. C) Vacuole: This is a storage organelle found in plant cells that stores water, nutrients, and waste products. D) Mitochondria: Mitochondria are membrane-bound organelles found in both plant and animal cells. They are responsible for producing energy in the form of ATP through cellular respiration. Therefore, the correct answer is D) Mitochondria, as it is a part of a plant cell.

3. Which sentence uses the phrase "by the way" correctly?

• A. By the way, I forgot to tell you I won the lottery!
• B. He finished his report, by the way, it was very well-written.
• C. I have some news for you, by the way.
• D. By the way, the movie starts at 8 pm.

Correct answer: C

Rationale: Option C introduces additional information that is not directly related to the previous sentence, making it a natural use of "by the way."

4. Which property of matter refers to the measure of the force of gravity acting on an object?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: b

Rationale: Weight is the measure of the force of gravity acting on an object. It is calculated as mass multiplied by the acceleration due to gravity.

5. Which word best synonyms with the word "elated"?

• A. Angry
• B. Sad
• C. Excited
• D. Confused

Correct answer: C

Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.

6. The doctor carefully examined the patient. Which word is the comparative form of the adjective "careful"?

• A. careful
• B. carelessly
• C. more careful
• D. most careful

Correct answer: C

Rationale: The comparative form of an adjective compares two things.
