ATI Immune System Quizlet Questions
Question 1 of 5
Colostrum, the yellowish fluid, secreted by mother during the initial days of lactation is very essential to impart immunity to the newborn infants because it contains:
Correct Answer: D
Rationale: The correct answer is D: Immunoglobulin A. Colostrum contains high levels of Immunoglobulin A (IgA), which is crucial for imparting passive immunity to the newborn. IgA helps protect the infant's mucosal surfaces from infections. Natural killer cells, monocytes, and macrophages are not typically found in colostrum and are not responsible for conferring immunity to the newborn.
Question 2 of 5
Identify which statements are correct.
Correct Answer: D
Rationale: The correct answer is D because protozoans do not have cell walls. They are single-celled organisms that lack a rigid cell wall. This distinguishes them from other microorganisms like bacteria, fungi, and algae which have distinct cell wall compositions such as peptidoglycan, chitin, and cellulose respectively. Choice A is incorrect as not all bacteria have peptidoglycan in their cell walls, some have other types of cell wall structures. Choice B is incorrect as not all fungi have chitin in their cell walls, some may have different components. Choice C is incorrect as not all algae have cellulose in their cell walls, there are variations in cell wall composition among different algal species.

Which group(s) of fungi do not generally produce sexual reproductive structures and are also sometimes known as imperfect fungi?
Correct Answer: E
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Therefore, the correct answer
Question 5 of 5
Which compounds produced by microorganisms can cause fever in humans and can withstand autoclaving?
Correct Answer: D
Rationale: The correct answer is D, peptidoglycan. Peptidoglycan is a component of bacterial cell walls that can trigger fever in humans. It is a sturdy molecule that can withstand autoclaving. A: Endotoxin is a component of the outer membrane of Gram-negative bacteria, not resistant to autoclaving. B: Lipid A is the toxic component of endotoxin, not resistant to autoclaving. C: Lipopolysaccharide is the major component of the outer membrane of Gram-negative bacteria, not resistant to autoclaving.
