65 POINTS AND BRAINLIEST PLEASE HELP ASAP For this assignment, you will write a research essay, or create a presentation, about a scientist who contributed knowledge to the field of chemistry. Your essay, or presentation, should include the following information about your scientist:

Describe your scientist's contributions and innovations to his or her field.
How did your scientist's research and data influence future use of his or her findings?
Describe the background, interests, or goals that affected your scientist's observations and conclusions.
Once you have selected a scientist, you will need to locate at least three different reliable resources to use to conduct your research. You may use textbooks, the Internet, or library books. These resources should be cited within your presentation and should be listed in a bibliography that you submit with your essay, or slide presentation. Use the Citations, Essay Writing, and Finding Reliable Resources tutorials to guide your writing.

If you have another method by which you would like to present your research findings, please have it approved by your instructor before you begin writing. No matter what presentation style you choose, be sure to use complete sentences and paragraphs, and include all of the necessary research required. You should also review the grading rubric before you begin. Select one of the following scientists, or pick another scientist of interest with your instructor's permission, to conduct your research on: Rosalind Franklin

Rosalind Elsie Franklin (25 July 1920 – 16 April 1958)was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal and graphite. The DNA work achieved the most fame because DNA (deoxyribonucleic acid) plays essential roles in cell metabolism and genetics, and the discovery of its structure helped scientists understand how genetic information is passed from parents to children.

Franklin is best known for her work on the X-ray diffraction images of DNA which led to discovery of DNA double helix. Her data, according to Francis Crick, was "the data we actually used" to formulate Crick and Watson's 1953 hypothesis regarding the structure of DNA.Franklin's X-ray diffraction image confirming the helical structure of DNA were shown to Watson without her approval or knowledge. Though this image and her accurate interpretation of the data provided valuable insight into the DNA structure, Franklin's scientific contributions to the discovery of the double helix are often overlooked. Unpublished drafts of her papers (written just as she was arranging to leave King's College London) show that she had independently determined the overall B-form of the DNA helix and the location of the phosphate groups on the outside of the structure. However, her work was published third, in the series of three DNA Nature articles, led by the paper of Watson and Crick which only hinted at her contribution to their hypothesis.

After finishing her portion of the DNA work, Franklin led pioneering work on the tobacco mosaic and polio viruses. She died in 1958 at the age of 37 from complications arising from ovarian cancer.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
