Answer:
It is neural tissue that is dominated by the cell bodies of neurons, neuroglia, and unmyelinated axons, and surrounds the narrow central canal.
Explanation:
Grey matter is a part of the central nervous system that is found on the surface of the brain.
It is a neural tissues that has alot of cell bodies of neurons, neuroglia and contain more unmyelinated axons and surronds the narrow central canal.it is distinguished from white matter because it has alot of cell bodies and unmyelinated axons and also it is not as white as white matter with greyish color.
Grey matter form spinal tracts which are the pathways where signals are sent from the brain to all part of the body.

Answer:
A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes". ... In that case one gene has more than two alleles. An example of multiple alleles is blood type
Explanation:
DNA consists of four nitrogenous bases: A, T, C, and G. Because A and T form a pair and C and G form a pair, the percentage composition of A is equal to T and the percentage composition of C is equal to G. This is called Chargaff's Rule.
In this sample, 20% is T. Because the percent composition of A is equal to T, we can expect 20% to also be A. That means that A and T make up 40% of the sample. That leaves 60% of the sample as C and G. The percentage composition of C must be equal to G, so divide 60% by 2 to get 30% G and 30% C.
So the answer is 30%.
