White matter is the slightly more pale tissue in the areas of the brain and spinal cord. It consists of nerve fibers with their myelin sheaths (the fatty substance that surrounds and "protects" the axon.
Answer:
d. this is one part of the cell cycle.
Explanation:
The organism would not have to find a partner in order to reproduce.
Answer:
Hyperpolarization
Explanation:
At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).
It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.
