The myelin sheath is the structure some neurons have that increases conduction speed.
<h3>What is a neuron?</h3>
Information is transmitted via neurons. They communicate between various brain regions and between the brain and the rest of the nervous system through electrical impulses and chemical signals.
As we know,
An insulating layer of fatty tissue called the myelin sheath surrounds the axon of a neuron and speeds up the electrical signal transmission.
Thus, the myelin sheath is the structure some neurons have that increases conduction speed.

Answer:
bb
Explanation:
Allele B codes for blue colour.
Allele b codes for green colour.
A gene is usually denoted by two alleles and allele B is dominant over allele b. This means that when B and b are together as Bb, blue colouration will be expressed while green colouration will be repressed.
Hence, for the green colouration to be expressed, B must not be present. <em>The genotype therefore must be bb.</em>
Because they have added another solution, it means that the mixture was not yet saturated, so the correct answer is unsaturated, D
<h2>
Spring constant is 14.72 N/m</h2>
Explanation:
We have for a spring
Force = Spring constant x Elongation
F = kx
Here force is weight of mass
F = W = mg = 0.54 x 9.81 = 5.3 N
Elongation, x = 36 cm = 0.36 m
Substituting
F = kx
5.3 = k x 0.36
k = 14.72 N/m
Spring constant is 14.72 N/m
Answer:
You could move something across the Earth with a little push. It would make fuel really efficient on those pathways. You could make a floor that is impossible to walk on. Everybody would just fall without traction.
