1. Which of these can provide significant protein to a person on a vegan diet?

• A. Eggs
• B. Fish
• C. Tofu
• D. Leafy greens

Correct answer: C

Rationale: Tofu is a plant-based source of protein that can provide a significant amount of protein to a person on a vegan diet. It is made from soybeans and is a versatile ingredient that can be used in various dishes to increase protein intake. Tofu is a good option for vegans looking to meet their protein needs. Eggs and fish are not suitable for a vegan diet as they are animal products. While leafy greens do contain some protein, they are not considered a significant protein source compared to tofu.

2. Which of the following is an organ of the respiratory system?

• A. Brain
• B. Larynx
• C. Urethra
• D. Pancreas

Correct answer: B

Rationale: The larynx is an essential organ of the respiratory system. It plays a crucial role in producing sound, protecting the trachea from food aspiration, and regulating the airflow to and from the lungs. The brain is part of the nervous system, the urethra is part of the urinary system, and the pancreas is part of the digestive system. Therefore, they are not directly related to the respiratory system's functions.

3. A person who has damage to their ulnar nerve will have decreased sensation in which part of the body?

• A. Hand
• B. Arm
• C. Leg
• D. Foot

Correct answer: A

Rationale: Corrected Rationale: Damage to the ulnar nerve typically results in decreased sensation in the hand, particularly affecting the little finger and half of the ring finger. The ulnar nerve innervates the hand and is responsible for providing sensation to these areas. This nerve does not extend to the leg or foot, so choices C and D are incorrect. While the ulnar nerve travels through the arm, its primary sensory impact is felt in the hand, making choice B less specific and therefore not the best answer.

4. When an individual is under stress, hormones are released. Which of the following is not one of the locations in which hormones are released when under stress?

• A. Posterior pituitary
• B. Hypothalamus
• C. Adrenal cortex
• D. Parathyroid

Correct answer: D

Rationale: During stress, hormones are released from the adrenal cortex, posterior pituitary, and hypothalamus to help the body respond. The parathyroid gland, however, is not typically involved in the stress response by releasing hormones. The posterior pituitary releases hormones like oxytocin and vasopressin, the hypothalamus secretes corticotropin-releasing hormone (CRH) and vasopressin, while the adrenal cortex releases cortisol and aldosterone in response to stress. Therefore, the correct answer is 'Parathyroid.'

5. What is the primary role of the stomach in the digestive system?

• A. To absorb nutrients
• B. To break down food
• C. To secrete digestive enzymes
• D. To store glucose

Correct answer: B

Rationale: The primary role of the stomach in the digestive system is to break down food. It accomplishes this through the action of gastric acid and digestive enzymes, which work together to break down food into a semi-liquid mixture known as chyme. Option B, 'To break down food,' is the correct answer. Option A, 'To absorb nutrients,' is incorrect because absorption mainly occurs in the small intestine. Option C, 'To secrete digestive enzymes,' is partially correct as the stomach does secrete digestive enzymes, but its primary function is to break down food. Option D, 'To store glucose,' is incorrect as glucose storage primarily occurs in the liver and muscles, not the stomach.
