The correct answers are evolution, genetic mutation and selection.
The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.
These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.
There are chances that evolution took place over a period of time that changed the character in the horse.
Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.
The myelin sheath is consist of a cell called the glial
cell. The glial cell is the one responsible for providing assistance in neurons
as well as insulation of which will be in between of them. This type of cell is
usually seen in the CNS and it has different types.
The evaluation of their DNA and short tandem repeats will let them know if the birds are related or not. The genetic linkage will provide information about their common ancestry as well as if they belong to the same species, or are closely related species.
Anaerobically (in absence of oxygen), yeast cells may obtain energy by fermentation, resulting in the production of ATP, CO2 AND ETHANOL. This is called ethanol fermentation or alcoholic fermentation where sugars such as glucose, fructose, and sucrose is converted into cellular energy (ATP), producing ethanol and carbon dioxide as by products.
