The correct answer is C.
In the aquarium, the water plants would provide the O2 molecules necessary for the snail's metabolism and the snail would release the CO2 molecules that are a byproduct of his metabolism into the container. The CO2 would later be used by plants to make sugar in the process of photosynthesis, releasing more O2 and the cycle of two gases would be completed.
DNA is found in the nucleus of a cell. Depending on the type of cell, different parts of the DNA are used (example; if it's an eye cell, the DNA will use the segment that is dedicated to the functions of the eye). When a protein is needed, the DNA will split and in a process called transcription, the DNA messages are copied onto mRNA. The mRNA then leaves the nucleus through nuclear pores, and then travels through the cytoplasm to locate ribosomes which will produce the proteins needed to express whatever trait it codes for.
They float around and they give signals
Obtaining mRNA from the cell, then using reverse transcriptase enzyme to convert it into a stable cDNA (or copy of DNA) molecule for insertion into the bacterial cell.
I hope this helps!
