Answer:

Evolution - It occurs due to the continuous variations and diversifications coming from the past generations

Natural Selection - In this process, the individuals are naturally selected by the environment that fits in perfectly!

Evolution - Driven by natural selection

Natural Selection- Driven by new characters that are the results of mutations

Evolution - Duration of Action Acquires millions of years

Natural Selection - Can be done in a short duration

Evolution - Example ;- Darwin’s finches, bright-colored peacocks, Mexican cavefish, etc.

Natural Selection -Example ;- Tree-frogs are mostly eaten by snakes, giraffes with short and long necks, etc.

With the proper stimuli, chemoreceptors and mechanoreceptors are depolarized. This is a result of:Sodium channels opening as a r

Alex73 [517]

<h2>Sodium channels </h2>

Explanation:

Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli

Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
Action potential is an efficient signaling process by which distantly located cells communicate to each other
Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
