Type-II Diabetes, or non insulin-dependent diabetes mellitus (NIDDM) involves a disrupted insulin signaling mechanism [broken]. There is usually a problem with insulin receptors on cells, and not so much the insulin itself (or pancreas). Sometimes the cause of type-II is referred to as "insulin resistance."
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.
