Gray matter consists of the <u>unmyelinated axons</u> of neurons.
<u>Explanation:</u>
The outer layer of the brain consists of the grey matter and white matter. The grey matter gets its name by the pinkish grey colour obtained by the greyish colour of the neurons and the red colour from the capillaries.
The grey matter consists of the dentrites, axons and cell bodies and this is essential for memory, attention and learning.
The unmyelinated axons are not covered by the fat protein myelin and these axons carry signals.They are the ones to help the processing of information in the brain.
The answer will be increase slightly and then decrease. Hope you get it!
Aftershocks my dude, they're a killer.
Comparing the genomes of each species to see which are most similar
There are many varying characteristics and exceptions to each type of protist.
They have been previously categorized based on what they are not.
They are all eukaryotes composed of one or more cells that contain nuclei.
There are no exceptions to the characteristics of each type of protist.
They are microscopic and therefore too small to study accurately.
Recent studies show that protists have not descended from one common ancestor.
