1. Which of the following is NOT a typical component of healthy semen?

Correct answer: D

Rationale: Healthy semen is composed of sperm, fructose (sugar), and prostaglandins. Urine is not a typical component of semen. While semen is ejaculated during sexual activity, urine is expelled through a separate pathway in the male reproductive system. Therefore, the correct answer is 'Urine.' Choices A, B, and C are all components found in healthy semen.

2. Which of the following nerves has the longest axon in the human body?

Correct answer: C

Rationale: The sciatic nerve contains the longest axon in the human body, extending from the lower back down the leg. This nerve is responsible for innervating the muscles of the lower limb. The dorsal root ganglion and laryngeal nerve do not possess axons as long as the sciatic nerve, making them incorrect choices. Therefore, the correct answer is C, the sciatic nerve.

3. What is the muscular sac that stores urine until it is released from the body known as?

Correct answer: B

Rationale: The bladder is the muscular sac that stores urine until it is released from the body. It acts as a reservoir for urine until it is eliminated through the urethra. The urethra is the tube responsible for carrying urine from the bladder to the outside. The ureter transports urine from the kidneys to the bladder. The nephron is the structural and functional unit of the kidney involved in the filtration of blood and urine production. Therefore, the correct answer is the bladder, as it specifically fulfills the function of storing urine before its elimination.

4. What element is responsible for the green color of leaves?

Correct answer: A

Rationale: Magnesium is the correct answer. It is essential for the formation of chlorophyll, the green pigment in plants that is crucial for photosynthesis. Chlorophyll absorbs sunlight and uses its energy to convert carbon dioxide and water into glucose and oxygen. Iron, copper, and zinc do not play a direct role in the green color of leaves. Iron is more related to processes like electron transport, copper is involved in enzyme functions, and zinc contributes to the synthesis of plant growth regulators.

5. Which of the following correctly orders the route of a fetus during childbirth?

Correct answer: A

Rationale: The correct route of a fetus during childbirth is from the uterus, through the cervix, and then out through the vagina. The contractions of the uterus help push the fetus through the cervix and out through the vaginal canal during childbirth. Choice B is incorrect as it reverses the order of the cervix and uterus. Choice C is incorrect as it includes the vas deferens, which is not part of the female reproductive system. Choice D is incorrect as it lists structures from the female reproductive system but in the wrong order for childbirth.
