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
Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate the antibiotic has no “target” to attack in a virus however antiviral medications and vaccines are specific for viruses
<span>In the digestive system, the food and the
products of digestion pass through the muscular tube known as intestine. It extends
from the lower end of the stomach to the lower opening tract of the digestive
tract or the anus. The intestine is divided into two sections, the small and
large intestine. Although both parts receive the digestion and product of the
food, they differ in some areas. For the small intestine, its main function is
to carry out most of the digestive process such as absorbing the entire
nutrient you get from foods into your bloodstream. This function is not present
in the large intestine because the digested food is mixed with the digestive
juices form the small intestine and no nutrients left for the large intestine
to handle.</span>
