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.

Gray matter consists of the <u>cell bodies </u>(soma) and <u>dendrites</u> (branches) of neurons or the nerve cells.  

Explanation

The absence of myelinated sheaths of the neurons in gray matter gives its gray color. Along with soma and dendrites, gray matter also consists of axon tracts, neuropil, glial cells and blood capillaries. The volume of gray cells correlates with a person’s skills and abilities.

Both the brain and the spinal cord contains gray matter. Gray matter is involved in a number of brain activities like thinking and memory, seeing and hearing, decision making and self-control etc.

These statements describe three different reactions.
Arte-miy333 [17]

Answer: 2 - The nucleus of an atom is split apart

Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.

A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.

Answer:

What was the first hominid ancestor?

The first early hominid from Africa, the Taung child, as it was known, was a juvenile member of Australopithecus africanus, a species that lived one million to two million years ago, though at the time skeptical scientists said the chimpanzee-size braincase was too small for a hominid.
