Answer:
they are Na+, K+ and Ca2+ ion channels.
Explanation:
Ionotropic acetylcholine receptors are also called nicotinic acetylcholine receptors because beside acetylcholine (Ch) they respond to nicotine. These receptors are primary receptors in muscle for motor nerve-muscle communication that controls muscle contraction.
Two molecules of ACh are required for receptor to open. Since the receptors are linked to ion channels, the channels open. Opening of the channel allows positively charged ions to move across it: sodium enters the cell and potassium exits.
Answer: Smooth muscle
Explanation:
I got it wrong on usatestprep and when it showed me the answer key, smooth muscle was the correct answer.

Fungi release enzymes which in turn help in digesting external material. Then the fungi absorb that digested compound that is created by the enzyme. Plants normally make their own food by the process of photosynthesis. Plants take in water through the roots from the ground, absorb sunlight during the day and take in carbon dioxide from the air to make their nutrients. So plants are normally autotrophic in nature. Animals on the other hand consume plants as well as other animals to produce nutrients. So animals are mostly heterotrophic in nature.
Hi!
Protein does all of the following except for insulating the body. Insulation is not a function of proteins, but it is a function of lipids.
Hopefully, this helps! =)
Lava flowing because it would put a lot of weight(pressure) and high temperatures
