Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis.
I don't know exactly what you mean but the size of a group affects its defense because there is a larger group. Therefore, more people would be protecting it, adding more to its defense.
ATP is an energy carrier that holds energy after processes like cellular respiration. The body can turn ATP into energy to do processes like physical movement later on.
Hope this helps :)
If two angles are supplementary to the same angles then they are congruent.
This reaction is called a synthesis.
