1. The transfer of energy through feeding relationships in an ecosystem is called a:

• A. Food Chain
• B. Food Web
• C. Habitat
• D. Biome

Correct answer: A

Rationale: Rationale: A food chain is a linear sequence of organisms where each organism consumes the one below it and is consumed by the one above it. This transfer of energy through feeding relationships is a fundamental concept in ecology to understand how energy flows through an ecosystem. In a food chain, energy is transferred from producers (plants) to primary consumers (herbivores), then to secondary consumers (carnivores), and so on. Each step in the food chain represents a trophic level, and energy is lost as heat at each level, resulting in a pyramid-shaped energy flow. Food webs, on the other hand, represent a more complex network of interconnected food chains within an ecosystem. Habitats refer to the specific environment where an organism lives, and biomes are large geographical areas characterized by specific climate and vegetation types.

2. Which of the following processes breaks down cellular components for recycling or waste removal?

• A. Photosynthesis
• B. Cellular respiration
• C. Cell division
• D. Phagocytosis

Correct answer: D

Rationale: The correct answer is D: Phagocytosis. Phagocytosis is a process in which cells engulf and digest cellular components, pathogens, or other materials for recycling or waste removal. Photosynthesis (option A) is the process by which plants convert sunlight into energy. Cellular respiration (option B) is the process of converting glucose into ATP for energy production. Cell division (option C) is the process by which a cell divides into two daughter cells. Therefore, phagocytosis is the most relevant process that breaks down cellular components for recycling or waste removal.

3. Fertilization of the egg by sperm typically occurs in the:

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. Fertilization of the egg by sperm typically occurs in the fallopian tube. After ovulation, the egg travels through the fallopian tube where it can meet sperm for fertilization. The fallopian tube provides an ideal environment for fertilization to occur due to its proximity to the ovaries and the uterus. The other options, A: Ovary, C: Uterus, and D: Vagina, are not the typical sites for fertilization to take place. Therefore, the fallopian tube is the most appropriate location for the union of egg and sperm to form a zygote.

4. He raised the issue on giving priority to patient needs. Which of the following offers the best

• A. Assessing nursing needs and problems
• B. Giving instructions on how nursing care needs are to be met
• C. Controlling and evaluating the delivery of nursing care
• D. Assigning safe nurse: patient ratio

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.

5. Identify the preposition in the following sentence: The cat jumped over the fence.

• A. cat
• B. jumped
• C. over
• D. the

Correct answer: C

Rationale: Prepositions show the relationship between a noun or pronoun and another word in the sentence. "Over" indicates the position of the cat in relation to the fence.

6. A block slides down a frictionless inclined plane. What determines its final velocity at the bottom?

• A. The length of the incline
• B. The angle of the incline
• C. The mass of the block
• D. All of the above

Correct answer: B

Rationale: In the absence of friction, the final velocity depends only on the gravitational potential energy gained, which is determined by the height difference related to the angle of the incline.
