## anonymous 5 years ago Compare and contrast the structure and function of a compound light microscope and a scanning electron microscope. Be sure to discuss the structure and function of each as well as the function and usefulness of each when examining a specimen

Group of microscopic, single-celled organisms that inhabit virtually all environments, including soil, water, organic matter, and the bodies of multicellular animals. Bacteria are distinguished in part by their morphological and genetic features; for instance, they may have spherical, rodlike, or spiral shapes. They also can be divided into two main groups, gram-positive or gram-negative, based on the structure of their cell wall and their reaction to the gram stain. Many bacteria swim by means of flagella (see flagellum). The DNA of most bacteria is found in a single circular chromosome and is distributed throughout the cytoplasm rather than contained within a membrane-enclosed nucleus. Though some bacteria can cause food poisoning and infectious diseases in humans, most are harmless and many are beneficial. They are used in various industrial processes, especially in the food industry (e.g., the production of yogurt, cheeses, and pickles). Bacteria are genetically distinct from the archaea. As prokaryotic organisms (having no membrane-bound nucleus), they are also distinct from eukaryotes. See also budding bacteria, coliform bacteria, cyanobacteria, denitrifying bacteria, nitrifying bacteria, sheathed bacteria, sulfur bacteria

This is not germane in this group.

its more romaine :)

@tanusingh, did you read the question? @tiffany, this question surely belongs in one of the science groups, probably Chemistry or maybe Physics.

$\int_{\text{structure}}^{\text{fucntion}}\color{red}{\text{specimen}}d\color{blue}{\text{electron}}$

6. anonymous

it is more russian

7. anonymous

tanusingh's reply looks a wee bit copy-pasted... on an unrelated topic ;)

8. anonymous

maybe romain with russian dressing

9. anonymous

okay thanks for the critisicm ,i m a commerce student

10. anonymous

hey satellite are u a scientist

11. anonymous

satellite actually invented the bicycle.

12. anonymous

ohkay i invented chemistry

13. anonymous

No you didn't. That's a lie... because then you'd know that a microscope is not a microscopic organism :-P

14. anonymous

okay......thats fine.....atleat i help,,u didnt.

15. anonymous

lol I'm just gently jostling buddy.

16. anonymous

haha,sorry tiffany i cant help u
