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 plane would you use to separate the abdominal cavity from the thoracic cavity?

• A. Sagittal
• B. Transverse
• C. Frontal
• D. Coronal

Correct answer: B

Rationale: The transverse plane, also known as the horizontal plane, runs horizontally from left to right, dividing the body into superior (upper) and inferior (lower) parts. This plane is ideal for separating the abdominal cavity (located below) from the thoracic cavity (located above). The sagittal plane (choice A) divides the body into left and right portions, the frontal plane (choice C) divides the body into front and back portions, and the coronal plane (choice D) is another term for the frontal plane. Therefore, when looking to separate the abdominal cavity from the thoracic cavity, the transverse plane is the most appropriate choice.

3. Which hormone is released by the adrenal medulla?

• A. Cortisol
• B. Adrenaline
• C. Insulin
• D. Somatostatin

Correct answer: B

Rationale: The correct answer is B, Adrenaline (also known as epinephrine), which is released by the adrenal medulla during the body's fight-or-flight response. Adrenaline helps prepare the body for action by increasing heart rate, dilating air passages, and mobilizing glucose and fats for energy, among other physiological responses. Choice A, Cortisol, is a steroid hormone released by the adrenal cortex involved in the stress response and regulation of metabolism. Choice C, Insulin, is produced by the pancreas and regulates blood sugar levels. Choice D, Somatostatin, is a hormone that inhibits the release of several other hormones in the body, but it is not released by the adrenal medulla.

4. What is the primary function of the skin?

• A. To regulate body temperature
• B. To protect the body from external damage
• C. To produce vitamin D
• D. To produce red blood cells

Correct answer: B

Rationale: The primary function of the skin is to protect the body from external damage. While the skin also helps regulate body temperature and produces vitamin D in response to sunlight, its main role is to act as a barrier against harmful external factors, such as pathogens and physical injuries. Choices A, C, and D are incorrect because although the skin does play a role in regulating body temperature and producing vitamin D, its primary function is providing protection against external threats.

5. Which vitamin is essential for blood clotting?

• A. Vitamin C
• B. Vitamin K
• C. Vitamin D
• D. Vitamin B12

Correct answer: B

Rationale: Vitamin K is essential for blood clotting as it is necessary for the synthesis of proteins involved in the coagulation process, such as clotting factors. Without sufficient Vitamin K, the blood may not clot properly, leading to excessive bleeding. Vitamin C is important for collagen synthesis and immune function, Vitamin D is essential for calcium absorption and bone health, and Vitamin B12 is crucial for red blood cell formation and neurological function. However, when it comes to blood clotting, Vitamin K plays a vital role.
