What type of stimulus is required for an action potential to be generated? What type of stimulus is required for an action poten

Ivahew [28]

Answer:

A threshold level depolarization.

Explanation:

In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.

A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.

Which statement BEST supports the choice made in Part A? A The diagram shows four daughter gametes that have exchanged genetic i

lesantik [10]

A statement which best supports the choice made in Part A (independent assortment) is: C. The diagram shows four unique gametes that are the result of two chromosomes separating in different ways.

<h3>Mendel's law of independent assortment.</h3>

Mendel's law of independent assortment is a theory which states that the alleles of two or more different genes are sorted into unique gametes that are independent of each another.

This ultimately implies that, the allele that is typically being received by a gamete for one gene doesn't influence or affect the type of allele that is received for another gene.

Based on the biological process (independent assortment) shown in the image attached below for part A, we can infer and logically deduce that a statement which best supports the choice made is that he diagram shows four unique gametes that are the result of two chromosomes separating in different ways.
