<u>Answer:</u>
The typical state of a neuron is the<u> resting potential</u>, but when electrical signals stimulate it to its threshold, the <u>action potential</u> is immediately observed.
<u>Explanation:</u>
The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.
Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.
Answer:
B
Explanation:
The cell membrane is like a gate around the cell, it only lets certain substances come in and out of the cell.
the three general classifications are sensory neurons, motor neurons and interneurons. I don't know how they work together to produce a response to an environmental stimulus:( sorry
The answer is; B
Sometimes winds carry the sand of the beaches causing erosion. The fences act as breakers of this wind erosion. As wind tries to carry the sand, they encounter the fence and 'break'. Therefore, the sand is deposited along the fence forming a sand dune. These dunes also form protection from storm surges.
