Answer:
Chemically gated Na+-K+ channels
Explanation:
The acetylcholine receptors are the receptors or ion channel proteins which are considered the transmembrane proteins. The acetylcholine receptors are of two types depending on the ligand which binds that is either nicotinic or either muscarinic receptors.
When the acetylcholine binds the receptor molecule, the ion channels open up and allows the passage of the sodium and potassium ios which depolarizes the membrane potential and generates the action potential in the neuron.
Thus, Chemically gated Na+-K+ channels is correct.

B

for 2 water can erode rocks to make canyons and other rock formations 3 because some land mases were formed with water and 4 because in many countries there are monsoon seasons witch brings heavy rain and high humidity

Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. The gravitational pull of the sun and moon on the earth also causes waves.
