Question

66 multiple choice 2 points
the response to a second exposure to an antigen:
produces a larger antibody response than the initial exposure
all of the above
none of the above
utilizes immunological memory
produces a faster antibody response than the initial exposure

67 multiple choice 2 points
which of the following is a digestive enzyme secreted from the pancreas that works with bile salts to break down fats in food so they can be absorbed in the i
sucrase
amylase
lipase
protease

Explanation:

Analyze Question 66

The secondary immune response occurs upon re-exposure to an antigen. This response utilizes immunological memory (memory B and T cells), which allows it to produce a faster and larger antibody response compared to the initial primary exposure. Since the statements "produces a larger antibody response than the initial exposure", "utilizes immunological memory", and "produces a faster antibody response than the initial exposure" are all correct, the correct choice is "all of the above".

Analyze Question 67

The question asks for a pancreatic digestive enzyme that works with bile salts to break down fats. Lipase is secreted by the pancreas and hydrolyzes dietary lipids (fats) in the small intestine, working in tandem with bile salts which emulsify the lipids to increase their surface area.

Answer:

Question 66

• produces a larger antibody response than the initial exposure
• all of the above (Correct answer)
• none of the above
• utilizes immunological memory
• produces a faster antibody response than the initial exposure

Question 67

• sucrase
• amylase
• lipase (Correct answer)
• protease
