Chemistry
1. What is the term for a solution that has a lower concentration of solute compared to another solution?
- A. Saturated solution
 - B. Unsaturated solution
 - C. Dilute solution
 - D. Concentrated solution
 
Correct answer: C
Rationale: A dilute solution has a lower concentration of solute compared to another solution. The other choices do not accurately describe a dilute solution.
2. How does polarization affect the intensity of light passing through a polarizing filter?
- A. All light passes through regardless of polarization.
 - B. Light with the same polarization as the filter passes through, while others are blocked
 - C. Light with higher intensity passes through, while weaker light is blocked.
 - D. The intensity is reduced for all light, regardless of polarization.
 
Correct answer: B
Rationale: A polarizing filter only allows light waves with a specific polarization direction to pass through, reducing the intensity of waves with different orientations.
3. He emphasizes to the team that they need to put their efforts together towards the attainment
- A. Span of control
 - B. Unity of direction
 - C. Unity of command
 - D. Command responsibility
 
Correct answer: B
Rationale: The correct answer is B: Unity of direction. Unity of direction is a principle of management which states that all activities within an organization should be directed towards the same objectives. In this scenario, the leader is stressing the importance of aligning the team's efforts towards a common goal or objective. This ensures that everyone is working towards a shared purpose, avoiding conflicting or contradictory actions. Span of control refers to the number of subordinates a manager can effectively supervise. Unity of command relates to the principle that employees should receive orders from only one supervisor to avoid confusion and conflict. Command responsibility is a term often used in the context of accountability for actions taken under one's command. Therefore, the most appropriate concept in this context is Unity of direction.
4. Which hormone, produced by the thyroid gland, regulates calcium levels in the blood by enhancing calcium absorption in the intestines and reducing calcium loss in the kidneys?
- A. Calcitonin
 - B. Parathyroid hormone (PTH)
 - C. Thyroxine
 - D. Insulin
 
Correct answer: a
Rationale: The correct answer is A: Calcitonin. Calcitonin is a hormone produced by the thyroid gland that plays a crucial role in regulating calcium levels in the blood. It works by enhancing calcium absorption in the intestines and reducing calcium loss in the kidneys. This helps to maintain the proper balance of calcium in the body. Parathyroid hormone (PTH) works in the opposite way, increasing calcium levels in the blood when they are low. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and growth, not calcium levels. Insulin is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels. Therefore, the correct hormone in this case is Calcitonin.
5. What is the end result of mitosis in animal cells?
- A. The production of two identical daughter cells
 - B. The production of four haploid cells
 - C. The production of a single diploid cell
 - D. The production of a single haploid cell
 
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.
6. Which of the following is a unit of work and energy?
- A. Pascal (Pa)
 - B. Kilowatt-hour (kWh)
 - C. Coulomb (C)
 - D. Tesla (T)
 
Correct answer: b
Rationale: Kilowatt-hour is a unit used to measure both work and energy, especially in the context of electricity consumption.
