physics

1. What happens to the gravitational potential energy of an object as it falls freely?

Correct answer: a

Rationale: Gravitational potential energy decreases as an object falls freely due to a decrease in its height.

2. What is the term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure?

Correct answer: b

Rationale: Solubility is the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure. The other choices do not accurately define solubility.

3. What is the primary hormone released by the parathyroid glands?

Correct answer: C

Rationale: The primary hormone released by the parathyroid glands is Parathyroid hormone (PTH), which plays a crucial role in regulating calcium levels in the body. Insulin is produced by the pancreas to regulate blood sugar levels and is unrelated to the parathyroid glands. Calcitonin is produced by the thyroid gland and helps regulate calcium levels but is not the primary hormone released by the parathyroid glands. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and is also not released by the parathyroid glands. Therefore, the correct answer is C: Parathyroid hormone (PTH).

4. Antigenic variation, a common strategy used by some viruses, allows them to:

Correct answer: B

Rationale: Rationale: Antigenic variation is a strategy used by some viruses to evade the host's immune response. By constantly changing their surface antigens, viruses can avoid recognition and destruction by the immune system. This allows the virus to persist in the host and continue replicating, leading to prolonged infection and potential transmission to other hosts. Antigenic variation does not directly involve the production of toxins, survival outside a host, or rapid replication, making options A, C, and D incorrect in this context.

5. The following epithelium lines the inner surface of the oral cavity, providing a barrier against external insults. Which type of epithelium best fits this description?

Correct answer: B

Rationale: The correct answer is B: Stratified squamous epithelium. The oral cavity is subjected to mechanical stress and potential injuries from chewing and abrasive food particles. Stratified squamous epithelium is the best choice for this location due to its multiple layers of cells that provide protection against wear and tear. This type of epithelium is well-suited for areas that require a tough, protective barrier, making it ideal for lining the oral cavity. In contrast, simple squamous epithelium is a single layer of flat cells found in locations where filtration or diffusion occurs, not where protection is needed. Simple columnar epithelium and pseudostratified columnar epithelium are better suited for absorption and secretion functions in areas like the intestines and respiratory tract, respectively.

6. Acids are generally characterized by a sour taste and the ability to:

Correct answer: B

Rationale: Acids release hydrogen ions (H+) in solution, allowing electrical conductivity
