Question

Which of the following best describes negative feedback?
Question 3 options:

1) It causes an effector to signal the control center, which creates the stimulus to make a response.

2) It counteracts a change in a condition by causing the change to stop or to be minimized.

3) It produces a response by lowering a set point in the organism's metabolism.

4) It promotes decreases, rather than increases, in an organism's metabolism.

Answer 1

What do you think?

Answer 2

Or how about this lets look at each one individually, A first, When the effector sends a signal to the control center, is that a negative or positive?

Answer 3

I don't know. In negative feedback the gain is reduced but the output is increased.

Answer 4

I think the answer is choice 4 , because the others all have positive feedback, they all serve a good purpose which is why they were implemented.

Answer 5

So when the effector sends a signal to the control center it is a positive charge.

Answer 6

Thank you i have been staring at this question for awhile now trying to figure it out and i thought it was 4 but wasn't sure but a second opinion really helps!

Answer 7

Np :)

Answer 8

I don't think it is four. A negative feedback is not always associated with a specific decrease. In fact, negative feedback can cause increases if the feedback stop production of other regulatory molecules.

A specific example of increases is blood sugar. If the negative feedback system fails blood sugar levels increase.

Answer 9

If you know how a normal toilet works, the float that is used to regulate the level of water in the tank is a great example of a negative feedback system.

Answer 10

In negative feedback, input follows the output, if the output changes, the work of negative feedback is to change the input according to output and ensure the minimize change in output..
