Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
Answer:
D
Explanation:
Males have testes while females have ovaries
Rocks can oxidize in heat and the minerals can cause the rock to crack and break off .
slaking is physical weathering because the rock is still the same, but its wet.
chemical weathering would happen the most quickly in the amazon rainforest.
chemicals in water dissolving minerals in rock is chemical weathering.
erosion removes fertile topsoil, is caused mainly by wind and water, and <span>can decrease revenue from agriculture.
erosion can be reduced by planting trees and </span><span>contour plowing.

runoff happens when the ground cannot absorb anymore water is a true statement.</span>
I feel so bad for u that no one answered this Q!!! I have no idea... But I can help u get the answer. Download the app "Quizup", enter a random fake email and make a password.

2) post ur question in the feed and wait for an answer
Allow Quizup to send notifications, so u can see when u get answered!
Good Luck! I hope u get 100%! What bio lesson is this in FLVS? I may have already done this quiz. I'm on Module 7 right now, and in honors. I didn't take the module 6 "module exam" yet tho. I won't answer thru here, but text me at 1-(305)-915-1749
