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.
Answer:
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the length of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.

Answer:
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter.
...
How are ABO alleles inherited by our children?
Inherited Blood type of child
O from the mother B from the father B

Explanation:
During meiosis, sister chromosomes of a homologous pair separate into different cells during gamete formation . This mainly occurs in Metaphase I of meiosis where the homologous chromosomes line up the metaphase plate in their sets. Each chromosomes of a pair are then pulled to different poles of the cells separating them. Each of these chromosomes carries a set of alleles of a gene. Each cell/gamete, therefore, carried half the set of alleles of all genes compared to autosomal cells. There many combinations of these sets that can occur depending on the number of chromosomes the organism has.
These cells when combined with that of another parent during fertilization, form a zygote that grows and develops into a mature organism. The offspring will bear the characteristics of both parents because it inherits half a set of chromosomes from both parents.

Pollution caused the environment to become more darkly colored, so moths were selected to be blacks and greys. Before pollution they were white and lighter colors. <span />
