physics

1. Describe the concept of inertia in terms of Newton's first law.

Correct answer: c

Rationale: Inertia refers to an object's tendency to maintain its current state of motion (either at rest or in motion) unless acted upon by an external force.

2. Discern the INCORRECT function of the liver.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

3. Two cars with different masses collide head-on. Which car experiences a greater change in momentum?

Correct answer: B

Rationale: The car with the smaller mass. Although momentum is conserved in the collision, the change in momentum is inversely proportional to mass. Therefore, the car with the smaller mass will experience a larger relative change.

4. The energy absorbed during a chemical reaction is called:

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

5. Antidiuretic hormone (ADH) helps the kidneys regulate:

Correct answer: C

Rationale: The correct answer is C: 'Urine output by controlling water reabsorption.' Antidiuretic hormone (ADH) is released by the pituitary gland and acts on the kidneys to regulate water reabsorption. When ADH levels are high, the kidneys reabsorb more water, leading to concentrated urine and decreased urine output. This helps maintain the body's water balance and prevent dehydration. While ADH indirectly influences blood pressure by regulating blood volume, its primary function is to control water balance, not acid-base balance. Therefore, the correct answer is C.

6. Which element makes up the majority of the Earth's atmosphere?

Correct answer: A

Rationale: Nitrogen is the most abundant gas in the Earth's atmosphere, crucial for plant life and maintaining the planet's temperature balance.
