Chemistry

1. What is the law that states energy can neither be created nor destroyed?

Correct answer: B

Rationale: Law of Conservation of Energy. This law applies to both chemical and physical processes, including chemical reactions.

2. During gas exchange in the alveoli, what happens to oxygen?

Correct answer: B

Rationale: During gas exchange in the alveoli, oxygen is absorbed from the alveoli into the bloodstream. In the alveoli, oxygen diffuses across the thin walls of the alveoli and into the surrounding capillaries where it binds to hemoglobin in red blood cells. This oxygen-rich blood is then transported to the body's tissues for cellular respiration. Therefore, option B is correct as it accurately describes the direction of oxygen movement during the process of gas exchange in the lungs.

3. How is work defined in terms of force and displacement?

Correct answer: d

Rationale: Work is calculated as the force applied to an object multiplied by the displacement of the object in the direction of the force.

4. The largest lymphatic vessel in the body is responsible for draining lymph from most of the body. What is it called?

Correct answer: B

Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body and is responsible for draining lymph from most of the body. It collects lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities. The jugular vein (A) is a major blood vessel that drains blood from the head. The subclavian vein (C) is responsible for draining blood from the upper extremities. The aorta (D) is the main artery that carries oxygenated blood away from the heart. Therefore, the thoracic duct is the correct answer for the largest lymphatic vessel in the body.

5. Which element is used in fluorescent lamps and emits ultraviolet light when excited?

Correct answer: A

Rationale: Mercury vapor in fluorescent lamps generates UV light that excites phosphors on the lamp's inner surface, producing visible light.

6. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?

Correct answer: C

Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.
