Answer:
Vitamin C
Explanation:
Vitamin C is known as the ascorbic acid performs various functions in humans and is present as the constituent of the skin epidermis.
Vitamin C protects the skin from photodamage caused by the harmful UV radiations and helps in the synthesis of collagen, a type of connective tissue in the human body.
Vitamin C is involved in the hydroxylation of collagen synthesis which is important for the support of the epidermis and extracellular stability.
The deficiency of Vitamin C causes scurvy characterized y the fragility of blood vessels and bleeding.
Thus, Vitamin C is the correct answer.
The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
- K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
- Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
- Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
- Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.

The primary and most significant greenhouse gas emitted from human activities is carbon dioxide. Burning of fossil fuels is the major cause of increased carbon dioxide emission.The burning of coal, oil, and natural gas is an important energy source to produce electricity.
The pathway between the ventral tegmental area (VTA) and the Nucleus Accumbens is critical for the addiction process because lesions to this pathway eliminate addiction. It is a part of the brain.
<h3>What is the nucleus accumbens?</h3>
The nucleus accumbens refers to a part of the forebrain located in the hypothalamus.
The nucleus accumbens is an interface between motivation (i.e., stimuli) and the corresponding action (response).
The nucleus accumbens is fundamental in different responses such as, for example, rewards, stressful situations, drug behavior, etc.
