A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on <u>which of its </u><u>receptor(s</u><u>) are present on the </u><u>postsynaptic</u><u> (target) cell.</u>
<h3>How do excitatory and inhibitory neurotransmitters act?</h3>
Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).
With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

C
Explanation:
An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
Answer:
Hello! There are numerous things that support Darwin's theory of evolution, but the most credible ones include:
*Homologous structures - structures that are similar in structure but different in function (e.g. wing of a bat and arm of a human).
*Embryology - the study of embryos
*Continental drift - some fossils of organisms that were adapted to a different environment are often found in different climates/areas they don't seem to have been adapted to.
*DNA - similarities in the genomes of certain animals are often used to compare amino acid sequences and protein production.

Explanation:
Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with.
