Answer:
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscope

<span>I suspect this question should read "How long does a red blood
cell live." A red blood cell lives for between 100 and 120 days. It
takes 7 days for a new red blood cell to develop from stem cells. Stem
cells are similar to base cells. They can also be seen as a general
template from which specialized cells are made. Stem cells can be taken
from a newborn baby's umbilical chord or extracted from an adult blood
donor's blood.</span>

we have to explain it so police inform us
Answer:
mitochondria and chloroplasts

the theory says that the bacteria which used oxygen and changed it to ATP molecules changed into mitochondria and those that used light energy to manufacture their own food changed into chloroplasts.this happened after the small prokaryotes which were bacteria were engulfed by the bigger prokaryotes of which some managed to survive and lived together through symbiosis hence the evolution to mitochondria and chloroplasts creating a eukaryotic cell.
