Biology

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

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 vitamin is known to play a vital role in immune function?

Correct answer: D

Rationale: The correct answer is Vitamin D. Vitamin D is known to play a vital role in immune function as it helps regulate the immune system's response to infections and reduces inflammation. It is involved in the production of antimicrobial peptides that help fight off pathogens. Vitamin A is important for vision and skin health, Vitamin B12 is essential for red blood cell formation and neurological function, and Vitamin E is an antioxidant that protects cells from damage. However, Vitamin D specifically stands out for its crucial role in supporting the immune system, making it the correct answer in this context.

3. In a chemical reaction, the total amount of:

Correct answer: A

Rationale: The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction, only rearranged

4. Which additional information would be MOST relevant to the topic of the passage?

Correct answer: B

Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.

5. Which of the following hormones helps regulate blood pressure by affecting kidney function?

Correct answer: C

Rationale: The correct answer is C: Renin. Renin is an enzyme produced by the kidneys that plays a crucial role in regulating blood pressure. Renin helps control blood pressure by initiating a series of reactions that ultimately lead to the production of angiotensin, a hormone that constricts blood vessels and increases blood pressure. Insulin is a hormone that regulates blood sugar levels, not blood pressure. Testosterone and estrogen are sex hormones that do not have a direct impact on kidney function or blood pressure regulation. Therefore, the correct hormone that helps regulate blood pressure by affecting kidney function is Renin.

6. Imagine you have an element with atomic number 20 and mass number 40. How many neutrons does it have?

Correct answer: C

Rationale: Rationale: - The atomic number (Z) represents the number of protons in an atom. In this case, the atomic number is 20. - The mass number (A) represents the total number of protons and neutrons in an atom. In this case, the mass number is 40. - To find the number of neutrons, you subtract the atomic number from the mass number: Neutrons = Mass number - Atomic number. - Neutrons = 40 - 20 = 20. - Therefore, the element with atomic number 20 and mass number 40 has 20 neutrons.
