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. What is the difference between a ventral and dorsal root of a spinal nerve?

Correct answer: A

Rationale: The correct answer is A: 'Ventral carries motor, dorsal carries sensory information.' Ventral roots of spinal nerves contain motor fibers that carry signals from the central nervous system to muscles and glands, controlling movement and function. Dorsal roots, on the other hand, contain sensory fibers that transmit information such as touch, pain, and temperature from the peripheral nervous system to the central nervous system for processing. Understanding this distinction is crucial for comprehending how information is transmitted and processed in the nervous system.

3. Which functional group is commonly found in ketones?

Correct answer: B

Rationale: Ketones have the functional group -CO-, which is a carbonyl group. The other choices are associated with different functional groups

4. Nuclear fusion powers the sun and other stars. What is the main obstacle to achieving controlled nuclear fusion on Earth for energy production?

Correct answer: D

Rationale: The main obstacle to achieving controlled nuclear fusion on Earth for energy production involves a combination of factors. A) Lack of suitable materials to handle high temperatures and pressures is a significant challenge due to the extreme conditions required for fusion reactions. B) Limited availability of fusion fuels like deuterium and tritium can pose a constraint on the scalability and sustainability of fusion energy. C) Difficulty in containing the plasma where fusion occurs is another critical issue as plasma instabilities and heat losses can hinder the efficiency of fusion reactions. Therefore, all of the options (A, B, and C) contribute to the challenges in achieving controlled nuclear fusion for energy production on Earth.

5. Which of the following is an example of a chemical change?

Correct answer: C

Rationale: Rusting is a chemical reaction where iron reacts with oxygen and water to form iron oxide (rust).

6. What type of bond involves the complete transfer of electrons between atoms?

Correct answer: B

Rationale: Ionic bond - Electrons are completely transferred from one atom to another, creating cations and anions with strong electrostatic attraction.
