Question

Which sentence describes an example of a positive feedback loop?

A: Warm blooded animals were when they get too hot. Sweating as a method by which the body close itself.
B: A thermostat regulates. Temperature by turning a furnace or air conditioner on and off.
C: When blood flows from a mild cut, blood clots form to prevent excessive bleeding.
D: As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.

Answer 1

The example of a positive feedback loop from the provided options is D: As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.

Step-by-step explanation:

The question relates to the concept of feedback loops in biological systems, particularly the difference between negative and positive feedback loops. The sentence that describes an example of a positive feedback loop is: As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures (option D). This example illustrates how a change in the system leads to an increase in the response, further promoting the initial stimulus, which is characteristic of a positive feedback loop. In contrast, negative feedback loops involve actions that counteract a change, aiming to maintain or reduce the response.
