Answer: nucleus
Explanation: The nucleus contains the DNA which is a genetic material that contains all the instructions for protein synthesis. Before proteins are produced, the DNA is first of all copied into an single stranded RNA in a process known as transcription. This process takes place in the nucleus. The single stranded RNA then leaves the nucleus to the ribosome where protein synthesis takes place, there the RNA is translated into a polypeptide chain.
These sorts of studies can help researchers determine the relative importance of nurture and nature in determining a trait. Nature here would refer to genetics passed down to an individual from its parents, whereas nurture refers to the environment the individual is exposed to.
it would be B. the intertidal zone only cover by high tides
I would say true. I say this because there have been times where scientists find out that there are better ways of performing experiments, or found that certain materials work better for certain tasks. (Especially true in medicinal fields!)
