The correct answer is: a gene may represent only a millionth of the cell's DNA.
The method used to amplify DNA fragments is called polymerase chain reaction (PCR). PCR is a technique used in molecular biology to produce thousands to millions of copies of a single targeted DNA sequence. When studying a specific gene, the scientist needs to be able to target and focus only on the DNA sequence which constitutes this exact gene. However, a gene is only a very small portion of an organism's genome. Therefore, the scientist uses PCR to amplify this DNA sequence and produce a large number of copies.
Hypothalamus. The hypothalamus is located at the base of the brain. It makes hormones that control hormones released in the pituitary gland. The hypothalamus controls water balance, sleep, temperature, appetite, mood and reproductive behaviors, and blood pressure.
Cerebellum controls balance for walking and standing, and other complex motor functions while the temporal lobe plays the role in processing affect/emotions, language and certain aspects of visual perception.
Explanation:
The mid-oceanic ridges are formed by the process of plate tectonics. Mid oceanic ridges are series of linear mountain ranges along divergent margins on the ocean floor.
- When two tectonic plates diverges, or moves apart, molten materials from the asthenosphere rises to the surface.
- The surface is the ocean floor. ]
- The new magmatic body is predominantly basaltic magma.
- On the ocean floor, older part of the oceanic plate moves backward away from the margin.
- The new ones crystallize and sets at the edge of the margin.
- This then forms the mid oceanic ridge.
- As the plate keeps diverging, more crustal materials are deposited and formed here.
