In the depolarization step of action potential where the membrane resting potential is reversed by the rush of sodium ions into a neuron.
A membrane potential shift from -70mV to +30mV for a limited period of time is known as an action potential.
The moving action potential has three stages:
1) The depolarization step, where sodium ions rush into a neuron and reverse the membrane resting potential; and
2) repolarization, which is a mechanism that restores the resting voltage of the membrane and the ionic concentration in the cell, is caused by the closure of the voltage-gated sodium channels and the opening of the potassium channels.
3) Hyperpolarization, when excessive potassium ion efflux occurs as a result of some open potassium channels increasing potassium permeability and causing a drop in the membrane potential.
4) The action potential, which is a transient reversal of membrane potential that travels through the axon, comprises three phases that are described above.

Because I had the question and I got it right
angle of incoming sunlight
Explanation:
The single feature that primarily determines the variation in climate in different parts of the world is the angle of incoming sunlight.
- Climate is simply an extended study of weather over a long period of time.
- The elements of weather like temperature, pressure, rainfall all conditions climate.
- The angle of incoming sunlight is by far the most important factor that determines climatic patterns on the earth.
- Around the equator, the sun is overhead and these regions are usually hot driving a wide range of weather phenomenon.
- The polar and temperate regions receive diffused sunlight because the sun is at an angle there.

Answer:
The monomers combine with each other via covalent bonds to form larger molecules known as polymers.
Explanation:
A monomer is a type of molecule that has the ability to chemically bond with other molecules in a long chain; a polymer is a chain of an unspecified number of monomers. Essentially, monomers are the building blocks of polymers, which are more complex type of molecules
and example of such is seen in several monosaccharides (glucose, fructose)joining together to form polysaccharide like starch
