Anatomy

1. The adaptive immune system has two main branches: humoral and cell-mediated immunity. Which type of immune cell is primarily responsible for antibody production?

Correct answer: C

Rationale: The correct answer is C: B cells. B cells are a type of lymphocyte that plays a central role in humoral immunity by producing antibodies. When activated by antigens, B cells differentiate into plasma cells, which are responsible for producing and secreting antibodies. Helper T cells (option A) primarily assist in activating B cells and other immune cells. Cytotoxic T cells (option B) are involved in cell-mediated immunity, where they directly kill infected cells. Natural killer cells (option D) are part of the innate immune system and target virus-infected and cancerous cells. Therefore, B cells are the immune cells primarily responsible for antibody production in the adaptive immune system.

2. What type of joint allows for the most movement?

Correct answer: A

Rationale: Rationale: A ball-and-socket joint allows for the most movement among the options provided. This type of joint is characterized by a rounded end of one bone fitting into a cup-like socket of another bone, allowing for a wide range of motion in multiple directions. The shoulder joint is a prime example of a ball-and-socket joint, enabling movements such as flexion, extension, abduction, adduction, and rotation. In contrast, a hinge joint (option B) like the elbow primarily allows for movement in one plane (flexion and extension). Fibrocartilaginous joints (option C) like the wrists have limited movement due to the presence of cartilage between the bones. Suture joints (option D) in the skull are immovable joints that provide structural support but do not allow for significant movement.

3. What is the term for the reaction between an acid and a base to produce water and a salt?

Correct answer: b

Rationale: Neutralization is the reaction between an acid and a base to produce water and a salt. The other choices do not accurately describe neutralization.

4. What is the main function of the endoplasmic reticulum (ER) in the cell?

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing

5. Which property of a substance refers to the force exerted on an object due to gravity?

Correct answer:

Rationale: Weight is the measure of the force exerted on an object due to gravity. It is calculated as mass multiplied by the acceleration due to gravity.

6. What is the characteristic property of acids?

Correct answer: b

Rationale: Acids typically have a sour taste. The other choices do not accurately describe the characteristic properties of acids.
