Answer:
<em>The correct option is d) once the electrical impulse reaches a certain level of intensity (its threshold), it fires and moves all the way down the axon without losing any intensity.</em>
Explanation:
In the field of biology, the all-or-nothing law can be described as a principle which focuses on the strength with which a nerve or muscle fibre responds to a particular stimulus, this strength being independent of the strength of the stimulus. The functioning of the impulse is just like the trigger of a gun. The more the force of a stimulus, the more will be the intensity of the nerve impulse.

Because they were passed down from a common ancestor, homologous structures are those found in related organisms that are comparable. These structures might or might not serve the same purpose in their offspring. The hands of various different mammals are depicted in the figure below. The basic skeletal structure of each is the same.
What is offsrping?
a person, animal, or plant's offspring or progeny is the result of reproduction. Parental transmission of the illness can affect children, a human or animal's direct offspring; a person born of parents gave birth to a lone child.
Creating offspring is considered reproduction. Reproduction comes in two basic forms: sexual reproduction and asexual reproduction. A sexually reproducing creature integrates the genetic material of both parents to create a genetically distinct individual. Asexual reproduction involves the self-replication of one parent to create genetically identical kids.
