Chemistry

1. What is the pH of a solution with a hydrogen ion concentration of \(1 \times 10^{-9}\) M?

Correct answer: c

Rationale: The pH is calculated as the negative logarithm (base 10) of the hydrogen ion concentration. In this case, \(-\log(1 \times 10^{-9}) = 9\).

2. He wants to influence the customary way of thinking and behaving that is shared by the

Correct answer: A

Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.

3. Which type of cell division is responsible for sexual reproduction?

Correct answer: B

Rationale: Rationale: Meiosis is the type of cell division responsible for sexual reproduction. During meiosis, a single cell undergoes two rounds of division to produce four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction, as it ensures that when two gametes (sperm and egg) combine during fertilization, the resulting zygote will have the correct number of chromosomes. Mitosis, on the other hand, is a type of cell division that produces two daughter cells with the same number of chromosomes as the parent cell and is involved in growth, repair, and asexual reproduction. Amitosis is a rare form of cell division that does not involve the typical processes of mitosis or meiosis. Cytokinesis is the process of dividing the cytoplasm of a cell after mitosis or meiosis.

4. What is the muscular sac in the female body that nourishes and protects a developing fetus?

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus is a muscular sac in the female body where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment to the developing fetus and protects it throughout gestation. The ovaries produce eggs, the fallopian tubes transport eggs from the ovaries to the uterus, and the vagina is the canal leading from the uterus to the outside of the body. Therefore, the uterus is the specific organ responsible for nourishing and protecting a developing fetus in the female body.

5. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.

6. Which term refers to the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter?

Correct answer: c

Rationale: Density is the measure of the mass of a substance per unit volume and is commonly expressed in kilograms per cubic meter (kg/m³).
