Answer:
A
Explanation:
Supply always has to be higher than demand
Explanation:
Membrane transport proteins fulfill an essential function in every living cell by catalyzing the translocation of solutes, including ions, neurotransmitters, and numerous drugs across biological membranes
Answer:
it is c: Taking observations at precise intervals
Explanation: I just took the test.
Answer:
you will have a negitative amount
Explanation:
so there is 12 mounths in a year divided by 3 is 4 then times by 7 is 28.
so then 9,100 times .065 is 591.5 that is how much mony goes in the 3 months. Then you do 28 x 591.5 =16562 so you wont have any money left you will actually be in the negitatives.

Answer:
Hydrogen ion (H+) pumps work against their concentration gradient and therefore they need energy inputs from sources such as ATP
Explanation:
The hydrogen ion (H+) pumps are proteins that move protons across biological membranes. These pumps use energy in the form of ATP in order to generate a proton gradient on one side of the membrane. For example, in plants, H+ pump ATPases are able to generate an electrochemical gradient in the plasma membrane. In this case, the proton gradient is employed to drive secondary transport processes, thereby enabling the uptake of diferent metabolites such as nutrients, sugars, amino acids, etc., from the extracellular space.
