Answer:
They can use a technique called Polymerase Chain Reaction. This can be done in a test tube or even in a organism. It usually relies on something called Thermostable DNA Polymerase and Taq polymerase. It requires DNA primers that is designed specifically for that DNA region (interest).
This effect is called BISPHASIC RESPONSE of alcohol. Biphasic response refers to the dual effects that alcohol has on human body system. In the first phase, the drinker feel stimulated and excited while in the second phase, the drinker feel down and depressed.
Electron microscopes use _beam of electrons___ in order to allow for higher magnification and more detail when viewing specimens.
Explanation:
A beam of electrons has a shorter wavelength than normal light used in light microscopes, by approximately a factor of X 100000. Therefore, electrons microscope have the inherent attribute of having a very high resolution. They have been used to discover very small organelles in cells such as the ribosomes and mitochondria that cannot be clearly viewed even with the highest resolution in light microscopes.
