Certain genes that allow for a certain thing to happen are turned on or turned off as needed. A brain cell may have the gene needed to send electrical pulses to other brain cells or other parts of the body, whereas a heart cell may have the genes that allow it to contract to pump blood. (I don't know if those are real genes, but hopefully you get the idea)
After obtaining observations and results, the biologist should analyze the results to see if they are consistent with her hypothesis. After this analysis, the biologist should form a comprehensive conclusion and publish her results. Upon publication, she should suggest improvements to the experiment and also check peer reviews on the experiment to see what she can improve herself.

Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.
Answer:
C would be the incorrect statement.
Explanation:
When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.
Hope this helps :)
