Answer:

A. The number of electrons of a neutral atom always equals the number of protons.

Explanation:

Because the atom is neutral, meaning it has no charge, the protons and electrons would therefore have to be the same. Electrons carry a negative charge while protons carry a positive charge. If you had one more electron than proton, you would have a charge of -1. If they are equal, it would have no charge and be named neutral.

Why is there a synaptic delay in gustatory receptors that is not seen in olfactory receptors?.
mylen [45]

G-linked proteins are activated by odorants, as well as by sweet, bitter, and umami chemicals, though the specific action in the cell varies. Direct signaling pathways are triggered by sour and salt chemicals.

Gustatory receptors are found on the tongue's papillae and are utilized to sense flavor. The olfactory epithelium of the nasal cavity contains olfactory receptors. These are used to identify different odors. These receptors use sensory nerves to transmit sensory messages to the brain.

Gustatory receptors belong to the cells on the tongue that are specifically designed to perceive taste, whereas olfactory receptors refer to any of the nucleated, specialized cells of the mucous membrane of the nostrils that serve as the receptors for smell. So, the primary distinction between gustatory and olfactory receptors is this.

So, we can say that odorants, as well as sweet, bitter, and umami compounds, induce G-linked protein activities; however, the cellular response is different for each. Acidic and salty substances activate direct signaling pathways.
