Question

which description of a graph best represents a negative feedback loop for blood glucose regulation? * 1 point
a) a line that continually increases as glucose is added
b) a line that drops suddenly and stays low
c) a wave - like pattern where glucose increases after meals, then returns to baseline
d) a flat line showing no change in glucose over time

Explanation:

In a negative - feedback loop for blood glucose regulation, when blood glucose levels rise (such as after a meal), the body responds to bring the levels back down to a normal baseline. This results in a wave - like pattern over time. A continuously increasing line (a) does not represent regulation. A sudden drop and staying low (b) is not typical of normal regulation. A flat line (d) indicates no regulation or change in response to factors affecting glucose levels.

Answer:

C. A wave - like pattern where glucose increases after meals, then returns to baseline
