Answer:

Places with latitudes closer to the Equator have hotter climates. Places with latitudes closer to the Poles have colder climates. This happens because the Sun's rays hit them more or less directly.

The Sun powers life on Earth; it helps keep the planet warm enough for us to survive.

In neuroscience, depolarization is an "all or nothing" response; what does that
Tom [10]

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
