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.
The experimental protocol describes and determines materials, equipment, and procedures.
B.
Passive transport doesn't requireenergy (ATP), active transport doesrequire energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
The
correct answer is mutualistic bacteria in the hindgut of the termite digest the
cellulose into sugars.

Termites
depend upon the whole complex of microbes in their hindgut. Microbes inside the
termites help the breakage of the complex sugars like a cellulose into short-chain
fatty acids.</span>
