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: to predict the probability of offspring genotypes
Explanation: Punnett squares are developed to predict the probability of offspring genotype. Punnett square is a square shaped diagram used for predicting the possible genotypes of a cross between two organisms. Punnett square is named after Reginald C. Punnett, who invented the approach. In punnett squares, the genotypes of the parents are written on the top and left hand side of the square while the possible genotypes of their offsprings are written in the boxes.
It is the discomfort, inferiority, embarrassment, rejection, and disapproval we experience in our own skin when witnessing an act that we find repugnant, reprehensible, or pathetic on the part of another person.

<h3><u>Answer</u>;</h3>
d. Na+
<h3><u>Explanation</u>;</h3>
- The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others.
- <em><u>Small molecules that are non-polar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.</u></em>
- Charged ions such as N+ and K+ Cannot permeate the cell membrane for the since uncharged molecules repel uncharged molecules present in the membrane structure.
