Answer:
are densely packed with numerous mitochondria.
Explanation:
Mitochondria are considered as the energetic centers of the eukaryotic cells. These organelles (mitochondria) produce energy in the form of Adenosine Triphosphate (ATP) through the mechanism of cellular respiration, i.e., mitochondria are the organelles where aerobic phases of cellular respiration occur. In presence of oxygen, mitochondria convert chemical energy obtained from foods to ATP, which is the energy coin that cells use to carry out all their metabolic processes (e.g., reproduction, growth, development, etc). Thus, cells with high metabolic requirements need to have many mitochondria in order to produce more ATP.
Answer:
Yes

Vitamin C</h2>
Vitamin C, or ascorbic acid, is a vitamin that dissolves in water and can be found in citrus and vegetables. Vitamin C is key to preventing and treating scurvy, which is a disease that occurs from Vitamin C deficiency (most of the time due to malnutrition or severe alcoholism); the first symptoms of scurvy are weakness and fatigue, but if it does not get treated properly, it can progress to anemia, hemorrhage, periodontitis, changes in personality, and finally death.
Vitamin C is a necessary element for tissue healing, collagen synthesis, and neurotransmitter enzymatic production. It is vital for immune system function and is necessary for the functioning of numerous enzymes. It has antioxidant properties as well.

Answer:
The correct statement is - option B.
Explanation:
Unmyelinated axons are the axon that lacks the covering of scwann cells that form the myelin sheath which helps in the transfer or transmit the signals faster and more effectively in neurons. It acts as the insulating layer.
In absence of the myelin sheath, the action potential found everywhere along the length of the axon which leads to slow propagation than in myelinated axons.
Thus, the correct answer is - option B.
