describe rosalind franklin (the scientist) contributions and innovations to his field.

Rosalind Franklin decided she wanted to be a scientist at age 15. She trained as a chemist, was an expert in deducing the structure of molecules by firing X-rays through them. Her images of DNA  were used without her knowledge, where she later went on to do pioneering work on the structures of viruses.

She died of ovarian cancer at age 37, before she could be recognized for the magnitude of her work.

Rosalind Franklin's critical contributions were the understanding of molecular structures of RNA, DNA, certain viruses, coal and graphite. Franklin contributed that DNA molecules are shaped like a twisted ladder. Her photographs and studies provided evidence that DNA is made up of more than a single strand of nucleotide's.

She innovated the resolution of the cameras used in order to obtain the most detailed images yet of X-ray diffraction of DNA. The detailed images allowed her to make exact measurements related to the structure of DNA.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

i think the answer is composed of atoms
