Question

what is the flow of response to a stimulus in a negative feedback loop? 1) information relayed to central hub. 2) change occurs. 3) response to change. 4) sensors detect change. options: 2-4-1-3, 1-2-3-4, 3-1-2-4, 4-3-1-2

Explanation:

In a negative feedback loop, first a change (stimulus) occurs (step 2). Then sensors detect this change (step 4). Next, the information about the change is relayed to a central hub (like the brain or a control center, step 1). Finally, there is a response to the change (step 3) to counteract it and restore balance. So the order is 2 (change occurs) → 4 (sensors detect change) → 1 (information relayed to central hub) → 3 (response to change).

Answer:

2-4-1-3
