Blood lipids are a category of fatty acids, which are substances used within the body to perform essential functions. Which category of blood lipids is involved in the formation of atherosclerotic plaques?

The correct answer is- cholesterol

Explanation:

There are different types of fats present in our body like phospholipids, triglycerides, cholesterol. Cholesterol is the lipid that is responsible for causing atherosclerotic plaques. Atherosclerotic is a disease in which plaque is formed in the walls of arteries which reduce the diameter of the blood vessel.

The plague is mainly formed by the accumulation of cholesterol in the arteries. This plague can prevent our body organs to get oxygenated blood. People who smoke, eat a high cholesterol diet, have a sedentary lifestyle are at high risk of developing atherosclerotic plaques.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
