The correct answer is d. both excitation and inhibition.
There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).
Answer:
This is what we call Potential Energy and Kinetic Energy
Explanation:
If the bowler is rolling a ball, let's say 5 LBS, It should travel at normal speed.
The speed is also dependent on how the bowler throws the ball.
If they were to change the weight of the ball. It would most likely slow the ball down more, as it would be too heavy to go as fast if it was a lightweight ball.
It's like a person. The bigger and heavier they are, the slower they will move with their own consecutive speed. If they are lighter, they'll most likely go faster
