Answer:
C: The sun's energy heats the air which then heats the ground below it.
Explanation:
The correct option is B
Acetylcholine released into the junction between a motor neuron and a skeletal muscle binds to a sodium/potassium channel and opens it. This is an example of the ligand-gated channel.
The acetylcholine receptors are cation-selective members of the ligand-gated ion channels which are pentameric and also are oligomeric protein assemblies that process to convert a chemical signal through the postsynaptic membrane into an ion flux.
Acetylcholine opens the sodium and potassium channels of a cell which makes the concentrations of these two ions inside and outside stabilize and depolarize the membrane of the cell.
This depolarization will result in the formation of nerve impulses. The receptors in muscle fibers recognize acetylcholine as a sign of muscle contraction from neuron to muscle.
Therefore, acetylcholine receptors are actually pentameric ligand-gated ion channels but muscarinic acetylcholine receptors are coupled membrane proteins of seven helix G-proteins.

You haven't provided the terms. but
Enodocytosis is best term which classifies the uptake of particles by the cell.
Answer: Exponential growth
Explanation: as a population witches it’s carrying capacity, there is an increase in competition
During C. M phase , this would most likely occur because during Mitosis it is the physical separation of DNA , where chromatids are being split in half and so it might be possible that a chromatid might not have been split in half perfectly, resulting in genetic disorders.
