The resting membrane potential arises in

the first place due to the presence of cell membrane that has a monolayer of

phospholipids.

The protein labeled X is

likely a potassium leak channel protein, contributing to the movement of K⁺

down its concentration gradient.

The resting membrane potential arises in

the first place due to the presence of cell membrane made of phospholipid

bilayer.

The protein labeled X is

likely a voltage gated sodium channel

protein.

The

axon of the neuron

is

generally much longer in length than dendrites.

Parasympathetic

activation causes bronchial dilation to facilitate deep, relaxed breathing

during rest-and-digest states.

Parasympathetic

stimulation of the heart decreases cardiac output, conserving energy during

restful states.

Parasympathetic

input enhances digestion by increasing peristalsis and enzyme secretion in the

gastrointestinal tract.

The

sympathetic nervous system promotes urinary bladder contraction to expel waste

rapidly during emergencies.

As the person eats the pizza, digestive enzymes are secreted to help break down the food, and the endocrine system releases hormones that signal the release of these enzymes. However, signaling by the endocrine system is generally slower and less specific than signaling by the nervous system.
