Verizon [17]

Answer:

Option C, open chemically gated sodium ion channels.

Explanation:

The nicotinic receptors are present on the muscle cell membrane. These receptors belong to the class of cholinergic receptor which binds to the acetylcholine and opens the gated channel to allow transfusion of cation through it. These actions of the receptors are stimulated by the neurotransmitter. Nicotinic receptors are very fast at acting and hence are more prevalent at the neuromuscular junction.

Hence, option  C is correct

What are the two main types of chemical bonds?​
antoniya [11.8K]

Answer:

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

Hope it helps!!!

Which sense would you expect a deep-ocean organism to rely in the least
Phantasy [73]
They should rely less on sight because the deeper you go down the less sunlight the reaches down because it refracts and gets dispersed. So it could be the middle of the day and it would look like the middle of the night down there.
