I believe Action potential is the brief wave of positive charge that sweeps down the axon. Axon is part of the neuron that conducts impulses from the dendrites towards the cell body along the neuron. The action potential is brief since the sodium channels can only stay open for a very brief amount of time. As it travels along the neuron there is a change in polarity across the membrane of the axon .
Best answer is D) groundwater
Caves generally form by the slow (very very slow) dissolution of soluble rock, such as limestone, which is dissolved by the acid in groundwater. Stalagmites and stalactites are evidence of this very slow dissolution process.

Answer:
Force exerted on the car = 4,000 N
Explanation:
Mass of the car (m) = 2000 kg
Acceleration(a) = 2 m/sec²
By Newton's second law of motion,
F (force) = m a
Putting the values of m and a
= 2000 x 2 = 4,000 N
Answer:
his movement is proportional to the intensity of the earthquake,
Explanation:
An earthquake is a record of the intensity of an earthquake as a function of time.
Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.
And the in x corresponds to time
