Plato answer:

Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

Nerve impulse is a wave of electrical charges that travel along the axon or dendrites of a neurone. a neurone will not transmit an impulse unless the stimulation is strong enough. once the magnitude / size of the stimulation reaches a sufficient level, a full sized impulse is generated to travel the entire length of the axon.

The number of sunflower sprouts will be higher than birch tree sprouts because sunflower sprouts have a higher growth rate than birch tree sprouts.

<h3>What is the growth rate?</h3>

Growth rate refers to the ratio of development of a given population and/or biological structure.

The growth rate may result very useful in ecology studies as above mentioned (ecological succession).

In conclusion, the number of sunflower sprouts will be higher than birch tree sprouts because sunflower sprouts have a higher growth rate than birch tree sprouts.

The gene for flower position in pea plants exists as axial or terminal alleles. Given that axial is dominant to terminal, list a

____ [38]

Answer:

A A

a Aa Aa

All the offspring have flower located at axial position

A a

A AA Aa

a Aa aa

Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position

Only offspring with genotype "aa" will have flower located at terminal position

Explanation:

Let the allele "A" represent the characteristics of axial position of flower

Let the allele "a" represent the characteristics of terminal position of flower

Given -

"A" is dominant over "a"

F1 generation -

Two parents with homozygous genotype for both A and a are crossed . The punnet square for the cross between "AA" and "aa" is as follows -

A A

a Aa Aa

Thus the genotype of offspring is "Aa"

Since, "A" is dominant over "a", all the offspring have flower located at axial position

F2 generation-

The cross between two parents having heterozygous genotype "Aa" will take place .

The punnet square for the cross between "Aa" and "Aa" is as follows -

A a

A AA Aa

a Aa aa

Three offspring with genotype i,e Aa, Aa and Aa will have flower located at axial position

Only offspring with genotype "aa" will have flower located at terminal position

Adult skin cells can no longer become other types of cells because they have already undergone

Ludmilka [50]

The answer is differentiation.

Differentiation is the process changing less specialized cells to more specialized. In differentiation cells develop to possess a more distinct form and function.Completely differentiated cells cannot further differentiate to any other type of the cells. Adult skin cells have their own function and structure so they are <span>completely differentiated.</span>
