The adaptations of organisms in a specific ecosystem are clues of evolution. for example, a giraffe has a long neck to reach leaves of high trees, birds migrate when cold weather comes etc
Answer:
The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein. The pulmonary vein and aorta also have valves connecting them to their respective ventricle.
Explanation:
C raccoons because they eat a wide variety because they can adapt more easily than other populations
<span>DNA polymerase is the enzyme that connects new nucleotides and proofreads them into separate DNA strands.
This process is part of DNA replication. A cell's DNA is replicated before a cell divides. The two strands of a DNA molecule have complementary base pairs. Each strand in the pair consists of a nucleotide sequence which is able to provide the information to duplicate itself. Before the duplication occurs, the length of the DNA that is about to be copied must be unwound and the two strands must be separated. This is done by breaking the weak hydrogen bonds that link the pairs together. They must then be kept apart from each other to expose the bases so that the new nucleotide partners can bond to them. DNA polymerase is the enzyme that moves along the exposed DNA strand and joins the new nucleotides to manufacture a new DNA strand that is a duplicate of the original</span><span>

The discovery of DNA, as well as understanding of its functioning and structure, may well be the most essential findings of the last century.
The impact of the discovery of DNA on medical and scientific advancement has been huge, whether it involves the manufacturing and creation of drugs to cure the deadly diseases or to identify the genes, which stimulate several of the diseases.
The understanding of DNA and its structural composition has led to the discovery of various technologies that helps in the fields like genetic testing, identifying viruses, crime investigation, production of genetically modified organisms, and various others.
