Should people be allowed to ski or snowboard without a helmet?

Absolutely not! By wearing your helmet you are saving your life. If you don't wear a helmet and get in an accident, at that high speed you could die or suffer from a life long injury. Wearing your helmet substantially protects your head than not wearing an helmet.

Should governments set national laws about ski safety?

I think they should as it is very important to wear helmets as they are life saving. I also think that government officers such as police should give out tickets to those who don't wear helmets to make sure that they wear one.

Should resorts set helmet safety guidelines for their visitors?

I think they should as it is very important to wear helmets as they are life saving. It is very important to keep your tourists alive to keep up a good reputation.

Is wearing a helmet a personal choice and responsibility?

Well technically speaking it is a personal choice and responsibility, but for me I have to wear a helmet whenever I go out because I know that if I don't I could possibly die.

When chloride enters the neuron via chemically gated chloride channels, the membrane potential will become more negative than th

weeeeeb [17]

Answer:

hyperpolarization

Explanation:

<u>Neurons</u>, the main cells of the nervous system, <u>have a charged cellular membrane</u>.

Neurons communicate with each other by the transmission (sending and receiving) of electric signals called action potentials.

When a neuron is not communicating, we say it's at rest. <u>The resting membrane potential of neurons is negative on the inside</u>.

When neurons communicate, their membranes' charges change in response to external molecules. For this to happen, a neuron's membrane has "gates" to allow charged molecules (ions) enter and exit the cell. These gates are called ion channels.

<u>When positively charged ions enter the cell, depolarization happens</u>, decreasing the difference in voltage between the inside and outside of the cell membrane; the interior becomes less negative. This is how action potentials are generated.

For an action potential to happen, a neuron most receive a stimulus that starts depolarization of its membrane, once a specific threshold is reached (enough positive ions have entered), then there's no turning point and an action potential is generated, causing depolarization of the membrane. Then positive ions start leaving the cell causing a repolarization of its membrane, before it goes back to resting potential.

When negatively charged ions enter the cell, hyperpolarization happens, increasing the difference in voltage between the inside and outside of the cell membrane; the interior becomes even more negative than at resting potential.

Chloride is a negatively charged ion, so when it enters a neuron via its chloride channels, the membrane potential will become more negative than when it was at rest, causing hyperpolarization of the membrane.

The consequence of this hyperpolarization is inhibition of action potential generation, which means that the neuron can't communicate. This is because the inside of the cell is too negatively charged for it to be able to easily reach the action potential threshold.
