I'd say C because you can't scientifically decide if a person is a good person or not
A isn't right because you can guess what's in the box by weight or sound
B isn't right because you can physically open a clock up or something to see how it works
D isn't right because you can gather data based on what food the dog takes a liking to
E isn't right because you can gather data of the nutrition of popcorn and apples
So that leaves C
Carbon dioxide is generated in tissues as a byproduct of normal metabolism. It dissolves in blood plasma to form carbonic acid (H2CO3); red blood cell (RBC) carbonic anhydrase catalyzes this reaction. Carbonic acid then spontaneously dissociates to form bicarbonate (HCO3−) and a hydrogen ion (H+). In response to the decrease in intracellular <span>pCO2</span>, more CO2 passively diffuses into the cell.
Cell membranes are generally impermeable to charged ions (i.e. H+, HCO3− ) but RBCs are able to exchange bicarbonate for chloride using the anion exchanger protein Band 3. Thus, the rise in intracellular bicarbonate leads to bicarbonate export and chloride intake. The term "chloride shift" refers to this exchange. Consequently, chloride concentration is lower in systemic venous blood than in systemic arterial blood: high venous pCO2 leads to bicarbonate production in RBCs, which then leaves the RBC in exchange for chloride coming in.<span>[2]</span>
