<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
Answer:
A "chain reaction" is a reaction that promotes or spreads the reaction. PCR rapidly makes a bunch of copies of a specific DNA sample and can "promote" the increase the amount of DNA.
Explanation:
I'm not straight up for sure but I think it is "for example"
Answer:
A: haploid, each containing 23 chromosomes
Explanation:
The cliellum is located on the anterior end of the earthworm. The anterior end of the earthworm is used in mating, and the mouth and brain are also located in the anterior end.
