Viruses have the ability to reproduce on their own and
sometimes within hosts. It is an infectious agent that can affect all types of
life forms (e.g. animals, plants, microorganisms). They are found in almost
every ecosystem on Earth and they are the most abundant type of biological
identity. Asvirology is the study of
viruses which is a sub-specialty of microbiology. The spread in many ways and
can be transmitted from one organism to another or sometimes to multiple
organisms at the same time. Its origins in the evolutionary history of life is
still unclear but they are considered to be life forms because of their
capacity to carry genetic material, reproduce, and evolve through natural
selection. </span>
I would say D- acidification of the ocean caused by increased atmospheric carbon dioxide emissions that dissolve in water.
It would be "the amount of ATP produced" that best distinguishes glycolysis and the Krebs cycle from the electron transport chain since this is the basis of energy creation.
Somatic mutations are acquired after birth in non-reproductive cells. These changes occur in only certain cells of the body and can be caused by tobacco use, ultraviolet radiation, viruses, chemicals and age. Acquired mutations are the most common cause of cancer.
Humans experience many somatic mutations over a lifetime, and the human body is normally able to correct most of these changes. This is why there is only a small chance of one mutation causing cancer. It normally takes many mutations over a lifetime to cause cancer. This is why older people are the most likely group to get cancer, as they have had more chances for mutations to build up.
