extinct organisms; that is, they belong to species that are no longer living anywhere on Earth. (3) The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time.
Answer:
The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.
Explanation:
The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.
Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.
During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
