Answer:
genetic drift
Explanation:
Genetic drift is an evolutionary force that requires the presence of a small population. It is a random process that fixes one or other alleles randomly in the gene pool of a population. Genetic drift does not take account of survival fitness imparted by alleles to the individuals. Since random and chance events such as the death of all the individuals having a certain allele in a population affect the small population more intensely, genetic drift works on small populations only.
Answer:
A. It results in the number of chromosomes being reduced by half.
Explanation:
In the process of meiosis, one cell is divided 2 times to form 4 daughter cells. These 4 daughter cells have half the number of chromosomes that of the parent cell.
The order of flow of oxygen within the human body may be described simply. Oxygen first is inhaled through the nasal cavity and then passes through the trachea, through the bronchi and into the lungs. In the lungs, the oxygen is passed into the blood stream through the alveoli and then is carried to the heart. The heart pumps this oxygenated blood throughout the body, primarily to organs and muscle cells, where it is consumed in respiration and is converted to carbon dioxide and excreted.
