Answer:
1. Based on their physical features and conduction properties
2. 80m/s to 120m/s
3. Has both sensory fibers and motor fibers
4. Group B conduct at 3m/s to 15m/s
5. Group C conduct at 0.5m/s to 15m/s
6. They generally have low conduction velocity and are polymodal
Explanation:
Axons were know to have different thickness and this differences were thought to relate to the speed at which the action potential could travel. This hypothesis was proved by Erlanger and Gasser.
Definition:
Having two different alleles of a particular gene or genes.
(an Allele is a variant form of a gene.)
Simplification:
If the organism has one copy of two different alleles, it is heterozygous.
Eg: T and t
<em> </em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>T</em><em> </em><em>for </em><em>tall</em><em> </em><em>and</em><em> </em><em>t</em><em> </em><em>for</em><em> </em><em>short</em><em>)</em>
Example:
<u><em>Pea</em><em> </em><em>Plants</em></u>
Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

I would say C but In the integumentary system there are four main tissue types, those are Epithelial, Connective, Nervous and Muscular tissue
