Physics

1. When light reflects from a surface, what determines the angle of reflection?

Correct answer: C

Rationale: The angle of reflection is always equal to the angle of incidence according to the law of reflection, regardless of the material, wavelength, or intensity.

2. "Ironic" and "serious" are:

Correct answer: B

Rationale: "Ironic" means the opposite of "serious."

3. Which of the following is NOT a function of the skeletal system?

Correct answer: A

Rationale: The correct answer is A. The skeletal system provides support and structure to the body, allowing for movement and protecting internal organs. The production of red blood cells occurs in the bone marrow, which is a function of the skeletal system. Additionally, the skeletal system stores minerals like calcium, which play a crucial role in bone health and overall bodily functions. Insulation of the body is not a primary function of the skeletal system but is rather a function of adipose tissue and the integumentary system. Therefore, option A is the correct answer as it does not align with the functions of the skeletal system.

4. What is the process by which a cell divides into two or more new cells?

Correct answer: A

Rationale: Rationale: Mitosis is the process by which a cell divides into two identical daughter cells. This type of cell division is essential for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Therefore, meiosis is not the process by which a cell divides into two or more new cells. Option C is incorrect because meiosis is not involved in the general process of cell division to produce new cells. Option D is incorrect because mitosis is the correct process for cell division.

5. What is the process of breaking down fatty acids into acetyl-CoA, a key molecule in cellular respiration, called?

Correct answer: A

Rationale: Rationale: A) Beta-oxidation is the process of breaking down fatty acids into acetyl-CoA molecules. This process occurs in the mitochondria and is a crucial step in fatty acid metabolism for energy production. B) Lipolysis is the breakdown of fats into fatty acids and glycerol, but it does not specifically refer to the conversion of fatty acids into acetyl-CoA. C) Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production and is not directly related to the conversion of fatty acids into acetyl-CoA. D) Nucleic acid catabolism refers to the breakdown of nucleic acids into nucleotides and does not involve the conversion of fatty acids into acetyl-CoA.

6. What is the relationship between mass and inertia?

Correct answer: a

Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.
