Physics

1. Which state of matter has a definite shape and volume but can flow?

Correct answer: B

Rationale: Liquids have a definite volume but can take the shape of their container, unlike solids with fixed shapes and volumes.

2. Which of the following hormones is produced by the adrenal medulla and prepares the body for a stressful situation?

Correct answer: C

Rationale: The correct answer is C: Epinephrine (adrenaline). Epinephrine is produced by the adrenal medulla and is responsible for preparing the body for a stressful situation, often referred to as the 'fight or flight' response. Testosterone is a hormone produced by the testes in males and in smaller amounts by the ovaries in females, responsible for male sexual characteristics. Cortisol is produced by the adrenal cortex and plays a role in regulating metabolism and immune response. Growth hormone is produced by the pituitary gland and is essential for growth, cell repair, and metabolism. Therefore, epinephrine is the hormone specifically produced by the adrenal medulla to prepare the body for stress.

3. What is the main function of calcitonin, a hormone produced by the thyroid gland?

Correct answer: D

Rationale: The correct answer is D: 'Lower blood calcium levels.' Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the blood. It works by inhibiting the breakdown of bone, which in turn lowers the amount of calcium released into the bloodstream. This process helps to decrease blood calcium levels when they are too high. Options A, B, and C are not functions of calcitonin; instead, they are more closely associated with other hormones such as thyroid hormones, vitamin D, and growth hormone, respectively.

4. 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.

5. What is the recommended daily intake of protein for adults to maintain healthy muscle mass?

Correct answer: C

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is 1.5 grams per kilogram of body weight. Protein is essential for muscle repair and growth, and consuming an adequate amount helps support overall muscle health. 1 gram per kilogram of body weight is generally recommended for sedentary individuals, but for those looking to maintain or build muscle mass, a higher intake of 1.5 grams per kilogram of body weight is advised. Consuming too little protein can lead to muscle loss, while consuming too much may strain the kidneys. Therefore, 1.5 grams per kilogram of body weight strikes a balance for most adults looking to support their muscle health.

6. What term describes the phenomenon of two waves canceling each other out when they meet?

Correct answer: C

Rationale: Destructive interference occurs when two waves meet and their amplitudes are such that they cancel each other out, resulting in a wave with a smaller amplitude or no wave at all. This is in contrast to constructive interference, where two waves combine to produce a wave with a larger amplitude. Refraction and diffraction are phenomena related to the bending of waves as they pass through different mediums or obstacles, respectively.
