physics

1. Which property of a wave represents the distance between two successive identical points on a wave?

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. What is the correct way to write "25th anniversary" as a word?

Correct answer: D

Rationale: Ordinals (numbers with "th", "st", "nd", etc.) are generally written as words when used before nouns. Option (d) is correct.

3. Antidiuretic hormone (ADH) plays a crucial role in regulating water balance. When ADH levels are high, what happens to urine production?

Correct answer: B

Rationale: When antidiuretic hormone (ADH) levels are high, it indicates that the body needs to conserve water. ADH works by increasing the permeability of the collecting ducts in the kidneys, allowing more water to be reabsorbed back into the bloodstream. This action leads to a decrease in urine production, as the body retains more water to maintain proper fluid balance. Therefore, the correct answer is B: 'Urine production decreases to conserve water.' High levels of ADH help the body prevent dehydration by reducing the amount of water lost in urine.

4. Fertilization, the fusion of sperm and egg, typically occurs in which part of the female reproductive system?

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. Fertilization usually occurs in the fallopian tube. After ovulation, the egg is released from the ovary into the fallopian tube where it can be fertilized by sperm. The fallopian tube provides the ideal environment for fertilization to take place before the fertilized egg travels to the uterus for implantation. The other options, such as the ovary, uterus, and vagina, do not typically serve as the site of fertilization. Therefore, the fallopian tube is the correct answer in this case.

5. What is the meaning of the idiom "to cross that bridge when we come to it"?

Correct answer: C

Rationale: The idiom suggests dealing with challenges as they arise, not before.

6. Which part of the respiratory system is responsible for gas exchange between the blood and inhaled air?

Correct answer: C

Rationale: The correct answer is C, 'Alveoli.' The alveoli are tiny air sacs located at the end of the bronchioles in the lungs where gas exchange occurs. Oxygen from the inhaled air diffuses through the thin walls of the alveoli and into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The trachea (A) is the windpipe that carries air to and from the lungs; the larynx (B) contains the vocal cords and helps with swallowing; and the pharynx (D) is the part of the throat that connects the mouth and nasal cavity to the esophagus and trachea, but it is not directly involved in gas exchange.
