Answer:
Both eukaryotes and prokaryotes have gene regulation strategies. By gene regulation, the amount of protein is maintained in the living cell.
In prokaryotes, operons are present which are controlled by a regulatory gene that regulates the synthesis of protein in prokaryotes. In eukaryotes, repressor and transcription activators regulate the expression of gene and protein formation.
So by gene regulation cell maintains the number of protein molecules to become too great for a cell. Without gene regulation the survival of any organism is not possible.
Answer:C. Creating helium from hydrogen in its core
Explanation: Stars produce energy majorly by nuclear fusion. The process of creating helium by merging hydrogen atoms to produce deuterium which in turn is converted to helium.
Well, basically, everything is made of atoms and cells. Those are youre building blocks for every life unit. The subunits of proteins are amino acids. These acids combine (in different combinations) to form different proteins.
The subunits of starch are carbohydrates. They build to form molecules of starch.
The
subunits of DNA are nucleic acids. These mix with other things to form
DNA. It is like the protein where different combinations create
different DNA strands/molecules.
