It serves as energy for the body the cells it helps carry out nerve ceel conduction muscle cell contraction, active transport and the production of chemical substances.
The right option is; Hooke
Robert Hooke was an English scientist that first recognized the cell as the universal unit of life. In 1665, Robert Hooke observed honeycomb-like structure when he viewed very tiny slices of cork using a coarse compound microscope. He called the structures cells but he did not know their actual structure and function.
The hours of daylight and dark time depends on where you are but how many snails and plants it takes to keep a stable environment my guess would be a few thousand snails and a couple thousand plants and also they have to be different kind of plants of so they can benefit from each other all around.
Answer:
Myelination
Explanation:
Myelin is a fatty substance composed of lipids which surrounds the axons of the nerve cells in the central nervous system. The myelin is formed by the oligodendrocytes in CNS and Schwann cells in PNS.
The plasma membrane of the oligodendrocytes containing the myelin covers the axons of the neurons in spiral fashion thus proving a sheath around through the process called "myelination".
This myelin sheath protects the neurons from the external environment as well as insulates the neuron which increases the efficiency of the impulse.
Thus, Myelination is the correct answer.
