Answer:
C. Electron beams have much shorter wavelengths than visible light
Explanation:
A beam of electrons is used to illuminate and create magnified images of specimens in an electron microscope. The resolution of a microscope increases with a decrease in the wavelength of the light it uses for illumination. The wavelength of electrons used in the electron microscope is about 100,000 times shorter than that of visible light. Therefore electron microscopes have a resolution thousand times better than the light microscope.

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p
Do u still need help I know how to do that
Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)
Explanation:
Speciation is not a mechanism of microevolution.
