I need help with the 2nd problem, the graph in the top is the info you need to know about it.

Cell C is the white blood cell

white blood cells need a lot of Mitochondria because since they hunt down pathogens in your bloodstream, they will need a lot of energy.

C goes into the last blank

Explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
