This is referring to meiosis, which happens just once to make reproductive cells, unlike mitosis which is just simple copying.
In mitosis, one cell splits into two, but the number of chromosomes doesn't change. The original cell makes two copies of its chromosomes and divides them up.

In <em>meiosis</em>, however, our cell doesn't bother making those two copies. It just takes what it has and divides it between two new cells.
The star turns matter into energy is the process of nuclear fusion. Nuclear fusion is a process where two or more atomic nuclei fuse to make a single denser, or larger nucleus.
Answer:
Antagonists
Explanation:
Antagonist induce the opposite effect to that of the neurotransmitter. They exert their effects by binding and altering the site at which the neurotransmitter functions. The antagonist may act competitive or non-competitive meaning they bind to the active site or non-active site, respectively.
Answer:
The answer to this question would be B(The black ball moved because the white ball transferred kinetic energy to it during the collision.)
Explanation:
For example, energy can't be created or destroyed, so D is wrong because it is saying the energy is naturally destroyed, C is incorrect because it didn't mention the collision, A is incorrect because it is saying energy is created. Because the law of conservation of energy states that energy can't be created nor destroyed
Only a little of the equator gets to experience day and night. When Uranus revolves around the Sun one part gets light and day while the other gets light and darkness. So it changes because one time you can be looking and its day. Then you will look again and it will be night since Uranus moved around the Sun.
