Thus, in insects, the blood and the interstitial fluid considered to be the same body fluid?
Answer: "To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells."
Nonrenewable sources deal with fossil fuels (coal, petroleum, etc) so renewable would be the sun, water, wind, things that can be replaced
Answer:
The movement of ions or molecules across a cell membrane into a region of higher concentration
To be able to compare the results to a sample without any of the independent variable added.
