1. Which property of a substance refers to its ability to be stretched into thin wires?

• A. Conductivity
• B. Viscosity
• C. Ductility
• D. Malleability

Correct answer: c

Rationale: Ductility refers to a substance's ability to be stretched into thin wires without breaking.

2. Nutrients are absorbed into the bloodstream through which part of the digestive system?

• A. Stomach
• B. Large intestine
• C. Small intestine
• D. Esophagus

Correct answer: C

Rationale: The correct answer is C: Small intestine. The small intestine is where most of the absorption of nutrients takes place in the digestive system. Its inner lining is covered with tiny finger-like projections called villi, which increase the surface area for absorption. Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream through the walls of the small intestine. The stomach primarily helps with the initial digestion of food, the large intestine absorbs water and salts, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, the small intestine is the main site of nutrient absorption in the digestive system.

3. As a young manager, she knows that conflict occurs in any organization. Which of the

• A. Can be destructive if the level is too high
• B. Is not beneficial; hence it should be prevented at all times
• C. May result in poor performance
• D.

Correct answer: C

Rationale: Conflict in an organization is a natural occurrence that can either be constructive or destructive. Option C is the correct answer because conflict may indeed lead to poor performance if not managed effectively. When conflict is left unresolved or unaddressed, it can create tension, decrease morale, and hinder productivity. By recognizing that conflict can impact performance, the young manager can take proactive steps to address and resolve conflicts in a constructive manner to minimize its negative effects and promote a healthy work environment.

4. What is the difference between mitosis and meiosis?

• A. Mitosis produces haploid cells, while meiosis produces diploid cells
• B. Mitosis involves crossing over, while meiosis does not.
• C. Mitosis results in four daughter cells, while meiosis results in two
• D. Mitosis is responsible for sexual reproduction, while meiosis is responsible for asexual reproduction.

Correct answer: C

Rationale: Rationale: - Mitosis is a type of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. Therefore, mitosis results in two daughter cells. - Meiosis is a type of cell division that results in four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction. - Option A is incorrect because mitosis produces diploid cells (cells with the same number of chromosomes as the parent cell), while meiosis produces haploid cells (cells with half the number of chromosomes as the parent cell). - Option B is incorrect because crossing over, the exchange of genetic material between homologous chromosomes, occurs during meiosis and not during mitosis. - Option D is incorrect because mitosis is not responsible for sexual reproduction; it is a process of asexual reproduction and

5. What is the SI unit of measurement for work?

• A. Newton-meter (N·m)
• B. Joule (J)
• C. Watt (W)
• D. Meter per second (m/s)

Correct answer: b

Rationale: Work is measured in Joules (J) in the SI unit system.

6. Which part of the brain is responsible for regulating body temperature, hunger, and thirst, and is considered a key player in the endocrine system?

• A. Amygdala
• B. Hippocampus
• C. Hypothalamus
• D. Thalamus

Correct answer: c

Rationale: The correct answer is C: Hypothalamus. The hypothalamus is a small region in the brain that plays a crucial role in maintaining homeostasis by regulating body temperature, hunger, and thirst. It also serves as a key player in the endocrine system by controlling the release of hormones from the pituitary gland. The amygdala is responsible for processing emotions and memory, the hippocampus is involved in memory formation and retrieval, and the thalamus acts as a relay station for sensory information. Therefore, the hypothalamus is the most appropriate choice for the functions described in the question.
