Answer:
Explanation:
This is because once a Voltage Gated Sodium Channels closes up after depolarization, they can not be reopened.The transmission of action potential is such a way that they are propagated one after the other in a forward direction, and never backwards. Thus once a sodium channel depolarizes,it closes up, to under go a shot rest.No matter the strength of the next stimulus it will not open. Then the channel ahead of it opens to depolarise to conduct action potential, this again after shut opening closes up for the channel ahead to open. This short period of rest when the sodium channels closes up is called refractive period. However after sometime of rest the rested sodium channels open, from the inactivated stage to conduct action potential.
There are 46 DNA molecules in each somatic cell.
Answer:
plant life use a system known as photosynthesis to make meals.
at some stage in photosynthesis, plant life entice mild strength with their leaves.
plant life use the strength of the solar to extrade water and carbon dioxide right into a sugar known as glucose.
glucose is utilized by plant life for strength and make different materials like cellulose and starch.
cellulose is utilized in constructing mobileular walls. starch is saved in seeds and different plant components as a meals source.

Answer:
<em>The correct option is B. Alleles</em>
Explanation:
The punnet square can be described as a diagram which shows the outcomes of a cross. A punnet square will help us know what will be the probability for a particular trait to occur in the offsprings.
Genes might have the same or different alleles. If the alleles for a gene are similar in an organism, the organism is said to be homozygous for the trait. If the alleles are different, then the organism is termed as heterozygous.
A dominant allele is the one which which suppresses the effect of the recessive allele. A recessive allele gets masked by a dominant allele.
