A researcher is observing human muscle cells through an electron microscope. They notice that cells from a more physically active individual
contain more of a certain organelle than those of a less active individual.
Which organelle are they observing?

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs. 

explanation:

sea breeze

cool air is going towards land allowing for the land to be cooler, the hotter air gets pushed away from the land.

i think that d. wind is the answer.   i missed the question when i answered a. currents.
