Anatomy

1. During sexual intercourse, sperm travels through a tube from the testes to the urethra. What is the name of this tube?

Correct answer: A

Rationale: The correct answer is A: 'Vas deferens.' The vas deferens is a tube that carries sperm from the testes to the urethra during ejaculation. It is a crucial part of the male reproductive system, allowing for the transport of sperm for fertilization. The epididymis is where sperm mature and are stored, not where they travel during intercourse. The seminal vesicle is a gland that produces a significant portion of the seminal fluid. The urethra is the tube that carries both urine and semen out of the body but is not where sperm travels from the testes.

2. Which of the following sentences uses the most formal language?

Correct answer: C

Rationale: The sentence uses more complex vocabulary ("cinematic experience") and avoids slang ("awesome," "flick").

3. What hormone signals the release of digestive enzymes from the pancreas?

Correct answer: D

Rationale: Rationale: A) Gastrin is a hormone that stimulates the release of gastric acid in the stomach, not digestive enzymes from the pancreas. B) Insulin is a hormone produced by the pancreas that regulates blood sugar levels by facilitating the uptake of glucose into cells, but it does not directly signal the release of digestive enzymes from the pancreas. C) Glucagon is another hormone produced by the pancreas that works opposite to insulin by increasing blood sugar levels, but it is not involved in signaling the release of digestive enzymes from the pancreas. D) Secretin is a hormone released by the small intestine in response to the presence of acidic chyme. It stimulates the pancreas to release bicarbonate to neutralize the acidity of the chyme and also triggers the release of digestive enzymes from the pancreas to aid in digestion. Therefore, secretin is the hormone that signals the release of digestive enzymes from the pancreas.

4. What is the functional group present in aldehydes?

Correct answer: B

Rationale: Aldehydes have the functional group -CHO, which is a carbonyl group bonded to a hydrogen atom. The other choices are associated with different functional groups.

5. A news article claims a scientist has discovered a cure for cancer. How should you approach this information?

Correct answer: B

Rationale: Extraordinary claims require extraordinary evidence. It's essential to wait for scientific consensus and verification before accepting such groundbreaking claims.

6. Which part of the brainstem controls heart rate and breathing?

Correct answer: B

Rationale: The correct answer is B: Pons. The pons is a part of the brainstem located above the medulla oblongata and plays a crucial role in controlling vital functions such as heart rate and breathing. It contains neural circuits that regulate the rhythmic patterns of breathing and works in coordination with the medulla oblongata to ensure proper respiratory function. While the medulla oblongata is also involved in regulating these functions, the pons is more specifically responsible for fine-tuning and coordinating the activity of these essential processes.
