Whether the effect of a neurotransmitter is excitatory or inhibitory depends on the receptor it binds to.
<h3>What is Neurotransmitter?</h3>
A neurotransmitter may be defined as the chemical substances present within the synaptic vesicles and transmitting the impulse through synapses.
Examples of excitatory neurotransmitters are glutamate, norepinephrine, epinephrine, etc. Such neurotransmitters promote the electrical impulse and allow the passage of messages.
Examples of inhibitory neurotransmitters are serotonin, glycine, GABA, etc. Such neurotransmitters inhibit the passage of electrical impulses and block information.
Therefore, it is well described above.

Answer:
The given cell represents an animal cell, in which the organelle labelled as 'G' is mitochondrion. Mitochondria are membrane-bound organelles and their inner membrane is folded inward to form finger-like structures or cristae.
The mitochondria are known as the powerhouse of the cells as they are site for biochemical reactions of respiration and energy production.
Thus, the correct answer is 'mitochondrion.'
Answer:
1-C............. ...............
Punnett squares are used to find out the possible genotypes of the next generation after a cross and thus find the phenotype too according to the predicted genotypes.
For example, parents with genotypes of Rr and rr cross together, we can use the punnett square to list out the possible genotypes of their children which are Rr and rr.
You can never predict the exact genotypes of the next child but you can find out the possibility if they carry a certain trait. All the genotypes of the child are in random but you at least know what phenotypes they'll have.
