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.
Observational study because the scientists are just observing the flock and not touching them or anything :)
Answer:Renewable resources include biomass energy (such as ethanol), hydro-power, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants).
So a natural resource would be trees because wood comes from trees.
