Recombinant DNA techniques, for example, increase milk productions in cows. Another example would be, transgenic salmon grow faster than wild salmon.
It's C. change over time. Happy to help!
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.
If I understand you correctly; the two experimental treatments are the experimental condition and the control condition.
The thing differing between them should be what you want to examine, and especially the thing you want to know of how it influences something. So for example if you want to know how alcohol influences something, the difference should be that one condition will include alcohol and the other won't.
A higher number indicates a higher concentration. The change will be positive where potato cylinders have increased in mass. Where the mass of potato cylinders has decreased, the change will be negative.
