Unmyelinated axons and neuronal cell bodies make up the majority of the grey matter.
The processes that emerge from the cell bodies of neurons and transmit messages between those cell bodies are known as axons.
These axons are primarily unmyelinated in the grey matter, which means that myelin, a whitish-colored, fatty protein, is not covering them.
In the brain, the grey matter is used to process information. Grey matter structures analyze signals produced by sensory organs or other regions of the grey matter.
This tissue sends sensory (motor) stimuli to the central nervous system's nerve cells, where synapses cause the nerve cells to respond to the stimuli. Through myelinated axons, which make up the majority of the white matter in the cerebrum, cerebellum, and spine, these impulses travel to the grey matter.

Answer:
CD40L
Explanation:
The CD40 ligand (CD40L) protein is a transmembrane glycoprotein which is expressed on activated T cells and belongs to the tumor necrosis factor (TNF) superfamily. The hyper IgM syndrome is caused by mutations in the CD40L gene, where the defective protein can no longer bind CD40 on antigen-presenting cells. The X-linked Hyper IgM syndrome is characterized by abnormal levels of immunoglobulins, i.e., low levels of IgG and IgA, and increased/normal levels of IgM. Because CD40L gene is located on the X chromosome, this disorder is observed much more frequently in males than in females.
You forgot to include the following choices but no worries I did this question before and the answers are:
advances in technology
increases understanding on environment
etc
<span>amylase is an example of an enzyme</span>
In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins.Proteins are biological macromolecule and mostly composed of enzymes. Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators.
