Explanation:
The fundamental microscopic components of all species are cells. Two groups of cells, Prokaryotes and Eukaryotes, exist. Prokaryotic (meaning pro: before and Karyon: for kernel/nut) identifies species that <em><u>do not have membranes surrounded by a cell nucleus or other organelles</u></em>.
Bacteria, thought to have evolved 3.5 billion years ago are types of prokaryotes and are the oldest forms of life on earth. As single- celled life forms, they take on various shapes (rods, cones, spheres, spirals) and are capable of reproduction through asexual binary fission, and exchange genes in horizontal gene transfer (conjugation, transduction etc) and cell fusion .
They live in communities and, grow exponentially in number over short periods of time. Some are autotrophs, capable of producing their own food through photosynthesis. Some species can move around using flagella, long whip-like projections from the cell.
In humans, bacteria have colonized the intestinal tract. While some are beneficial as part of the microbiome, others are disease-causing pathogens- these are typically eliminated via the use of antibiotics.
Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.so the signal speed might slow down as it got halved
Myelin is the insulating layer, or sheath that forms around the nerves, including those in the brain and in the spinal cord. It is made up of some protein and fatty substances. This myelin sheath is allows electrical impulses to the transmit quickly and efficiently along with the nerve cells. If the myelin is damaged, these impulses slow down.
Myelin is repaired or replaced by the special cells in the brain called as oligodendrocytes. These cells are made from special type of stem cell that found in the brain, called as oligodendrocyte precursor cells (OPCs).
