Anatomy

1. Which of the following is NOT a risk factor for developing atherosclerosis?

Correct answer: C

Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.

2. The hormone responsible for milk production in the breasts after childbirth is:

Correct answer: B

Rationale: The correct answer is B: Prolactin. Prolactin is the hormone responsible for milk production in the breasts after childbirth. It is produced by the pituitary gland and stimulates the alveoli in the breasts to produce milk. Estrogen plays a role in breast development during pregnancy but is not responsible for milk production. Oxytocin is responsible for the ejection of milk from the breasts during breastfeeding. Relaxin is a hormone that helps prepare the body for childbirth by relaxing the ligaments in the pelvis. Therefore, the hormone directly responsible for milk production after childbirth is prolactin.

3. Which element is a component of baking soda and is important for maintaining pH balance in the body?

Correct answer: D

Rationale: Sodium bicarbonate acts as a base and helps regulate pH in various biological systems

4. What is the outermost protective layer of the kidney?

Correct answer: C

Rationale: The correct answer is C, renal capsule. The renal capsule is a tough fibrous layer that surrounds the kidney and provides protection. It helps maintain the shape of the kidney and serves as a barrier against infections and injuries. The renal cortex (A) is the outer region of the kidney where filtration occurs. The renal medulla (B) is the inner region of the kidney where urine is formed and collected. The renal pelvis (D) is a funnel-shaped structure that collects urine from the kidney and funnels it into the ureter. Therefore, the renal capsule is specifically the outermost protective layer of the kidney.

5. The study of fungi is known as:

Correct answer: B

Rationale: Rationale: A) Virology is the study of viruses, not fungi. B) Mycology is the branch of biology that deals with the study of fungi. Fungi are a separate kingdom of organisms that include yeasts, molds, and mushrooms. C) Bacteriology is the study of bacteria, not fungi. D) Parasitology is the study of parasites, which can include various organisms such as protozoa, helminths, and some fungi, but it is not specifically focused on fungi.

6. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?

Correct answer: C

Rationale: While Newton's third law states that for every action, there is an equal and opposite reaction, the unbalanced force acting on each object depends on their respective masses. The larger mass of the table (compared to the book) experiences a smaller acceleration, making its movement almost imperceptible.
