Answer:

beneficial mutation

Explanation:

A mutation is any alteration in the genetic material of an organism. In general, mutations have a negative impact on the fitness (or reproductive success) of the individual that carries this mutation; however, there are situations where a mutation may be beneficial for the individual in a given environment. When a beneficial mutation occurs in the germline, it potentially can be passed to the next generation and progressively increases its frequency in the population.

at over 5 million degrees celsius the temperature of the sun core is high enough for nuclear to occur
Paraphin [41]

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!)
