1. How is power related to time?

Correct answer: c

Rationale: Power is the rate at which work is done or energy is transferred, and it is not directly linked to time.

2. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

3. Sunscreen protects the skin from harmful ultraviolet (UV) rays by

Correct answer: B

Rationale: The correct answer is B: Absorbing UV rays and converting them to heat. Sunscreen contains ingredients that act as filters to absorb UV radiation before it reaches the skin. These filters then convert the UV rays into a less harmful form of energy, usually heat, which is then released from the body. This process helps prevent UV radiation from damaging the skin cells and causing sunburn or long-term skin damage. Reflecting UV rays away from the skin (A) and blocking UV rays completely (C) are not accurate functions of sunscreen. Additionally, stimulating melanin production (D) is not a direct way in which sunscreen protects the skin from UV rays.

4. The "master gland" of the endocrine system, located at the base of the brain, secretes various hormones that control other glands is the:

Correct answer: B

Rationale: The correct answer is B: Pituitary gland. The pituitary gland is often referred to as the "master gland" because it plays a crucial role in regulating other endocrine glands in the body. It is located at the base of the brain and secretes various hormones that control functions such as growth, metabolism, reproduction, and stress response. The thyroid gland (A) regulates metabolism, the adrenal gland (C) produces hormones involved in stress response, and the pancreas (D) is primarily responsible for regulating blood sugar levels through insulin production, but they do not serve as the master gland of the endocrine system.

5. What is the process by which a fertilized egg implants itself in the lining of the uterus?

Correct answer: B

Rationale: The correct answer is B: Implantation. Implantation is the process by which a fertilized egg, or zygote, attaches itself to the uterine wall to establish a pregnancy. Fertilization is the fusion of sperm and egg to form a zygote, which occurs in the fallopian tube. Gestation refers to the period of development of the fetus inside the uterus. Parturition is the process of giving birth. Therefore, implantation specifically refers to the attachment of the fertilized egg to the uterine lining, making it the most appropriate answer in this context.
