When a small populations' gene frequencies are changed drastically by chance alone it is called a genetic drift
Answer:
In order to clone the sequence of the gene for one of the human crystallins found in the eye, there is a need for the application of polymerase chain reaction. In the process, the particular sequence of gene is denatured and then replicated various times to generate various clones of the gene sequence.
By producing various copies of the gene sequence for the human crystallin, that is, desirable, a scientist can examine various distinct characteristics of the protein as there is always more to examine with.
Answer:
the waters acts as a solvent for chemical reactions and also helps transport dissolved compounds in and out of cells.
Photosynthesis removes carbon dioxide naturally—and trees are especially good at storing carbon removed from the atmosphere by photosynthesis.
