Chemistry

1. What does the term "solute" refer to in a solution?

Correct answer: B

Rationale: The solute is the substance that dissolves in the solvent to form a solution. The other choices do not accurately describe the solute.

2. What is the end result of mitosis in animal cells?

Correct answer: A

Rationale: Rationale: Mitosis is a type of cell division that results in the production of two identical daughter cells, each having the same number of chromosomes as the parent cell. This process is essential for growth, repair, and maintenance of multicellular organisms. During mitosis, the replicated chromosomes are separated into two nuclei, and the cell then divides to form two genetically identical daughter cells. Options B, C, and D are incorrect because mitosis does not result in the production of four haploid cells, a single diploid cell, or a single haploid cell.

3. What is the phenomenon responsible for the mirage effect seen in deserts?

Correct answer: B

Rationale: Mirages occur due to the refraction of light by layers of air with different temperatures and densities, bending the light rays and creating the illusion of water on the horizon.

4. How does kinetic energy change when the velocity of an object is doubled?

Correct answer: b

Rationale: Kinetic energy is directly proportional to the square of the velocity of an object.

5. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.

6. Which structure helps regulate body temperature by constricting or dilating in response to temperature changes?

Correct answer: C

Rationale: The correct answer is C: Sweat glands. Sweat glands play a crucial role in regulating body temperature by producing sweat that evaporates from the skin surface, cooling the body when it's hot. Sweat glands can constrict to reduce sweating in cooler temperatures and dilate to increase sweating when the body needs to cool down. Sebaceous glands are responsible for producing oil to lubricate the skin and hair follicles help in hair growth. Langerhans cells are immune cells in the skin. Therefore, sweat glands are the structure specifically involved in regulating body temperature through constriction and dilation in response to temperature changes.
