Anatomy

1. The process by which a cell divides to produce two daughter cells is called:

Correct answer: A

Rationale: The correct answer is A: "Mitosis." Mitosis is the process of cell division in which a cell duplicates its chromosomes and divides into two identical daughter cells. This is a crucial mechanism for growth, repair, and maintenance of multicellular organisms. Meiosis (option B) is a different type of cell division that produces gametes with half the number of chromosomes. Differentiation (option C) refers to the process by which cells become specialized for specific functions. Transformation (option D) is a term used in molecular biology to describe the uptake of foreign DNA by a cell. In this question, the specific process of cell division leading to the production of two daughter cells aligns with mitosis.

2. What is the relationship between work, force, and displacement?

Correct answer: b

Rationale: Work done is the product of force and displacement in the direction of the force.

3. Which hormone is responsible for regulating blood sugar levels and is produced by the pancreas?

Correct answer: A

Rationale: The correct answer is A: Insulin. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. When blood sugar levels rise after a meal, insulin is released to help cells absorb glucose for energy or storage. This process helps to lower blood sugar levels. Glucagon, the hormone mentioned in option B, is also produced by the pancreas but has the opposite effect of raising blood sugar levels when they are too low. Testosterone and estrogen, options C and D, are sex hormones and are not directly involved in regulating blood sugar levels.

4. Based on the information provided, which statement is LEAST likely to be supported by the author?

Correct answer: B

Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.

5. What is the difference between active and passive immunity?

Correct answer: A

Rationale: The correct answer is A: "Active immunity involves the body's own immune response, while passive immunity provides immediate protection through antibodies from another source." Active immunity is long-lasting because it involves the body's immune system producing memory cells that remember specific pathogens, providing long-term protection. Passive immunity, on the other hand, is short-lived as it involves receiving pre-formed antibodies from an external source, such as through maternal transfer or injection of antibodies, which do not create memory cells for long-lasting protection.

6. Which of the following is a strong acid?

Correct answer: b

Rationale: Hydrochloric acid is a strong acid, meaning it completely ionizes in water to produce hydrogen ions. The other choices are weak acids.
