All energy flows linearly; that is, in one direction. There are several basic forms of energy, including kinetic, potential, heat, chemical, electrical, electrochemical, electromagnetic, sound and nuclear.
This can affect the organisms living there because now, their environment is probably different than what they have been living in for a long time, so now they have to adapt to this new environment, and if they don't, the organisms will probably end up dying.
DNA polymerase moves along the old strand in the 3'-5' direction, creating a new strand having the same 5'-3' direction.
Answer:
selective breeding; biotechnology
Explanation:
Selective breeding is a type of artificial selection that consists of crossing plants/animals with desirable and heritable phenotypic traits in order to increase the frequency of such traits in progeny. Selective breeding can be considered as one of the first biotechnological techniques applied by humans. In the past, the selective breeding technique has allowed obtaining domesticated animals (e.g., dogs from wild wolves) and domesticated crops from their wild ancestors (e.g., maize from its wild ancestor teosinte).
