I believe the answer to this one is (A) Single Gene Traits. I searched it up and it says “Widow’s peak occurs when the hairline forms a distinct point in the center of the forehead. Widow’s peak is controlled by a dominant allele (W).”
Answer:
All of the above
Explanation:
ATP synthase is a transmembrane protein enzyme. It harnesses the potential energy –proton motive force- created by the development of a proton gradient across a membrane (could be across the intermembrane space in chloroplast and mitochondria). As the H+ ions 'drain' back and pass through their channels in the protein enzyme, the synthase is able to phosphorylate ADP and Pi to form ATP.
These ATPs (from photophosporylation) in light-dependent phase, are used in the catabolism of glucose, in the light-indepedent phase.
Answer:
A nerve impulse
Explanation:
It's important to note that these signals not only connect the brain and spinal cord, but they also send signals to muscles and glands. People talk about nerve impulses when they talk about the electrical signal that goes down an axon.
