Anatomy

1. B cells in the immune system are responsible for:

Correct answer: B

Rationale: B cells in the immune system are responsible for producing antibodies specific to a pathogen. This is because B cells are a type of white blood cell that play a crucial role in the adaptive immune response. When a B cell encounters a specific pathogen, it differentiates into plasma cells that produce antibodies targeted against that particular pathogen. These antibodies then tag the pathogen for destruction by other immune cells. B cells do not directly attack and engulf pathogens like phagocytes, nor do they destroy infected body cells like cytotoxic T cells. Therefore, option B is the correct answer as it accurately reflects the primary function of B cells in the immune system.

2. Where does bile, a substance that helps digest fats, come from?

Correct answer: C

Rationale: Rationale: Bile is a substance that helps digest fats by emulsifying them, which means breaking down large fat globules into smaller droplets to increase the efficiency of fat digestion by enzymes. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to aid in the digestion and absorption of fats. The stomach (option A) is responsible for the initial digestion of food through the action of gastric juices, but bile is not produced in the stomach. The pancreas (option B) secretes digestive enzymes such as lipase to further break down fats in the small intestine, but it does not produce bile. The gallbladder (option D) stores and concentrates bile produced by the liver but does not actually produce bile itself.

3. Define power in physics.

Correct answer: b

Rationale: Power is the rate at which work is done or energy is transferred or converted.

4. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

Correct answer: B

Rationale: The correct answer is B: Atrophy. Atrophy is the process by which muscle tissue wastes away due to disuse or lack of nutrients. When muscles are not regularly used or do not receive enough nutrients, they can decrease in size and strength. Hypertrophy, on the other hand, refers to the increase in muscle size and strength through exercise and proper nutrition. Fibrosis is the formation of excess fibrous connective tissue in an organ or tissue, leading to scarring. Rigor mortis is a temporary stiffening of muscles that occurs after death. Therefore, in this context, atrophy best describes the wasting away of muscle tissue due to disuse or lack of nutrients.

5. What is the process by which a large, unstable nucleus splits into two smaller nuclei, releasing neutrons and energy?

Correct answer: D

Rationale: Nuclear fission involves splitting a heavy nucleus into smaller fragments, releasing neutrons and energy.

6. What is the main function of valence electrons in chemical bonding?

Correct answer: B

Rationale: They are involved in forming bonds with other atoms. Valence electrons occupy the outermost energy level and are readily involved in attracting other atoms through sharing or transferring electrons, forming chemical bonds.
