Answer:
B is INCORRECT
Explanation:
Action potential in contractile cells can be divided into 3 phases
1. Rapid depolarization; caused by fast influx of sodium ions into the cells. Last a few milliseconds.
2. Plateau phase: This is a sustained positive membrane potential, after rapid depolarization, caused by a balance between calcium ion influx and slow potassium ion efflux.
3. Rapid repolarization: Eventually there's a closure of all other ion channels except the potassium ion channels causing rapid efflux of potassium ions, returning the membrane potential back to negative.
A refractory period usually occurs after undergoing an action potential. During this time no action potential can occur.
Answer:
2. An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds.
3. they have a higher chance of survival if the germinated when the time wasn't right they would die
Answer:
BH BH bH bH
Explanation:
I used the foil method to solve the problem
Answer:
The correct answer will be option-A.
Explanation:
Oxidative phosphorylation is a process which leads to the formation of ATP molecule. During oxidative phosphorylation, the transfer of electrons from reducing equivalents like NADH and FADH₂ formed during cellular respiration to oxygen leads to the formation of ATP.
Since oxidative phosphorylation involves the transfer of electrons from these equivalents through the electron transport chain which takes place in the inner membrane space of mitochondria. Therefore, oxidative phosphorylation and electron transport chain are interlinked.
Thus, option-A is the correct answer.
<span> Meiosis is a pfocess in which one dilpoid cell divides to give four haploid cells
</span>one result of meiosis is <span> formation of gametes
Its essential process of sexual reproduction as a result gametes are formed
so correct option is D
