<h3><u>Answer;</u></h3>
d. a neuron recharges before it can fire again.
<h3><u>Explanation;</u></h3>
- <em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
- <em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
- There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
- Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.
The answer is true I’m pretty sure
Answer:
Bart was 16 years old when he moved to New Jersey. He was not happy there were very few kids his age in his new neighborhood. During the winter, he noticed that his elderly neighbor, Mr. Jones, was attempting to remove snow from his sidewalk. Bart ran over to Mr. Jones and offered to help him. When summer came, Bart wanted to go swimming in Mr. Jones' pool, and the elderly neighbor smiled and allowed him, with pleasure.
Explanation:
This is a good example of a Life Skills question, where you are being questioned on what is the correct way to deal with people in certain situations. If Bart had helped the elderly neighbor, he would have a positive interaction with him, meaning that he would then not be afraid to approach him in summer.
