Remember, diffusion is when molecules move from an area of HIGH concentration to an area of LOW concentration. Therefore, in this example the molecules on the outside, where the concentration is high, will diffuse to the inside of the circle, where the concentration is low.

Answer:
motor end plate membrane potential,
it applies all or none law. either it generates full threshold level potential or it does not produce any potential. after being released from the presynaptic neuron, ACh binds with the receptor of the postsynaptic neuron, which leads to the depolarization of the cell membrane by the increased transportation of Na and K. then, MEPP leads to increased depolarization in the postsynaptic membrane which is also known as end-plate potential.
A. is the incorrect statement.
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids. Codons provide the key that allows these two languages to be translated into each other.
