Answer:
Breathing rate is most likely to increase if the blood level of carbon dioxide increase.
Explanation:
Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.

Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
Answer:
D) epigenetic phenomena.
Explanation:
All that a living being is, anatomically and functionally, even in its behavior, is determined by the genes that in a very complex interaction with the environment build living beings. Genes articulate the responses of cells (and therefore of the organisms that carry them) to environmental stimuli, interaction with other genes (of other cells and other living things) and fundamentally direct the self-construction of any living being.
The genes regulate themselves, establishing a very sophisticated kind of program, with very precise spatial and temporal dimensions. How this regulation is achieved, what principles guide it is the subject of the study of molecular biology. But genes are also transferred from one generation to another. The cells divide and inherit their genes to the offspring. Other cells - gametes - carry the information to be inherited from parents to children or from generation to generation. What rules genes follow in this path of inheritance of individuals, species, populations, is the subject of study of genetics.
Genes are constructed of DNA (acronym that names deoxyribonucleic acid). The total gene content of an individual is called a genotype and the effect that the genotype activity causes on the individual (appearance, structure, functioning) we call it a phenotype. The mechanisms of functioning and regulation of genes involve chemical activity on DNA, including changes in its sequence (mutations). Epigenetic phenomena are defined as any change in gene expression (change in phenotype) that is inheritable but does not involve DNA mutations (genotype modifications). Epigenetics refers to any process of regulation of genes that do not imply changes in the DNA sequence. If the DNA contains information (genes), epigenetics deals with the genetic information that is outside the genes.
