The sun
Explanation:
The sun is the only star in the solar system. It is the center around which the known 8 planets and their planets revolves round giving an heliocentric system.
The solar system is but one of the systems in the milky-way galaxy.
The sun, our star provides energy for the whole solar system through a nuclear process occurring at its core.
- Nuclear fusion is the source of energy that the sun possesses.
- The process requires a very high activation energy in the presence of a high pressure and temperature to start up.
- During nuclear fusion, small atomic nuclei combines into larger ones with the release of a huge amount of energy.
- The energy released provides the needed heat to set up another fusion process. The process eventually degenerates into a series of chain reaction leading to the release of energy.
- This is what happens in the a star like the sun.

Reproductive isolation must happen
When water vapor condenses to become water again, it is relatively pure.
while it occurs during the water cycle, it can be used to purify water for drinking.
Hope this helps

14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
