Answer:
brainliest plzzzzz
Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.

pls make me as the brainliest Answer
Answer:
Yes (but not how you think)
Explanation:
I'm assuming that you mean if nuclear fusion, where two atoms (in this case mostly hydrogen) fuse into one heavier atom, and release a lot of energy.
However, fusion happens when there is a tremendous amount of pressure or heat. This is found in the core
The 5 million degrees is found on the surface of the sun, but at the core, it is at 15 million degrees.
In addition, the pressure is so extreme that if forces atoms to become one, despite the fact they don't like being together (try finding 2 strong magnets and hold them so that they try to repel each other and try and make them touch, it's hard! Now imagine having to put a million of times the amount of strength!)
So, the sun is capable of nuclear fusion, but at the core, where it is 15 million degrees!
(fun fact: scientists are trying to build "mini-suns" called Fusion reactors to try and harvest the power of the sun!)
