Answer:
It will overpopulate and harm

Answer:
I think your answer is wrong. The right answer is D. Nucleus & Ribosome.
Explanation:
A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis. 
 
        
             
        
        
        
Marine fish gills have cells that have the ability to can remove salt by pumping it into the salt water.
This is active transport in real life.

A law can be repeated every time while a theory can not a law has more facts and statistics supporting its results while a theory has not been proven and really just cant be trusted as much as a law.
