1. Which of the following is NOT a primary producer in an ecosystem?

Correct answer: B

Rationale: Rationale: - A) Grass: Grass is a primary producer because it can photosynthesize and convert sunlight into energy, making it the base of the food chain. - B) Deer: Deer are consumers that feed on primary producers like grass, so they are not primary producers themselves. - C) Algae: Algae are primary producers that can photosynthesize and produce energy from sunlight. - D) Mushroom: Mushrooms are decomposers that break down organic matter, so they are not primary producers.

2. What property of a substance refers to its ability to be drawn into thin wires without breaking?

Correct answer: c

Rationale: Ductility is the property that describes a substance's ability to be drawn into thin wires without breaking.

3. An ancient Egyptian pyramid has a square base with side lengths of 20 meters and a remaining height (after erosion) of 10 meters. Its original height was 30 meters. What was the volume of the pyramid in its original state?

Correct answer: A

Rationale: Use the formula for the volume of a pyramid with the original height and base area.

4. Which sentence uses the subjunctive mood correctly?

Correct answer: A

Rationale: Option A expresses a wish or hypothetical situation, requiring the subjunctive mood.

5. What does the term "colligative property" refer to in solutions?

Correct answer: b

Rationale: Colligative properties are dependent on the number of solute particles in a solution, not their nature. The other choices do not accurately define colligative properties.

6. What is the difference between exhalation (expiration) and inhalation (inspiration)?

Correct answer: B

Rationale: Option B is the correct answer because inhalation is the process of breathing in, where the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. This air is rich in oxygen, which is essential for cellular respiration. On the other hand, exhalation is the process of breathing out, where the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be expelled from the lungs. This air is depleted of oxygen as it has been used up during cellular respiration. Understanding the difference between inhaling oxygen-rich air and exhaling oxygen-depleted air is crucial for comprehending the respiratory system's function and the exchange of gases in the body.
