I would say it’s helps with basic reproduction and let’s animals develop more.
The question asks average kinetic energy. So it is only related with the temperature. The higher temperature is, the higher kinetic energy is. So the answer is (4).
Ernest Rutherford's gold-foil experiment showed the density of atoms.
<span>The experiment proved that most of an atom is empty space with a very small positively charged nucleus in the middle.
So, from the given statements he following is true:
</span><span>Ernest Rutherford's gold-foil experiment showed </span>the existence of a dense, positively charged center in an atom.
