1. Which sentence uses the colon correctly?

Correct answer: A

Rationale: Colons are used to introduce a list or explanation that follows an independent clause. Options (a) and (c) use the colon correctly.

2. What is the term for a group of organisms living in the same place and interacting with each other?

Correct answer: B

Rationale: Rationale: - A) Ecosystem refers to a biological community of interacting organisms and their physical environment. - B) Community specifically refers to a group of organisms of different species living in the same place and interacting with each other. - C) Population refers to a group of individuals of the same species living in the same area. - D) Niche refers to the role or function of an organism or species within an ecosystem. In this context, the term for a group of organisms living in the same place and interacting with each other is best described as a community because it involves multiple species interacting within a shared habitat.

3. What is the principle behind the phenomenon of refraction, where waves bend when entering a new medium?

Correct answer: C

Rationale: Refraction occurs because of the change in wave speed as it enters a new medium, causing the wavefront to bend and change direction.

4. What type of bone is the kneecap (patella)?

Correct answer: B

Rationale: The correct answer is B: Short bone. The kneecap, or patella, is classified as a short bone because it is roughly cube-shaped and is composed of spongy bone enclosed by a thin layer of compact bone. Short bones provide support and stability with limited motion, making them ideal for protecting joints like the knee. Long bones are typically elongated, flat bones are thin and curved, and irregular bones have complex shapes. Understanding the classification of bones can help in identifying their functions and structural characteristics.

5. Which of the following is the main function of the lungs?

Correct answer: D

Rationale: Rationale: A) To transport oxygen and nutrients throughout the body - While the lungs do play a role in transporting oxygen, their primary function is to exchange oxygen and carbon dioxide between the body and the environment. The transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, specifically the blood vessels. B) To coordinate movement and sensory information - This function is primarily carried out by the nervous system, specifically the brain and spinal cord. C) To filter waste products from the blood - The kidneys are responsible for filtering waste products from the blood, not the lungs. The lungs primarily function in gas exchange.

6. A satellite orbits the Earth at constant speed. Which force is responsible for its circular motion?

Correct answer: A

Rationale: This force acts towards the Earth's center, providing the centripetal force required for the satellite to move in a circle.
