Assume you are looking for microorganisms in a tissue sample from a lung biopsy. the microbes become apparent when you switch to 1000x. what type of microbe is most likely
Homework Answers
with 1000x magnification we can see bacteria because bacteria are very small and transparent hence needs higher resolution. At this magnfication, we are able to see 0.18mm microbes

Your professor has asked you to determine the tissue specificity of a growth factor you have identified called optimusprime. Based on previous research, you know that when skin epithelial cells are treated with optimusprime, they become mesenchymal in nature. You applied optimusprime to intestinal epithelial cells and epithelial cells from the lung in culture. For some reason, optimusprime was effective in lung cells but not in intestinal cells. Your professor is convinced that you must have done something wrong because...

microbiology case study (worth 25 points) 1) A first-year microbiology student clad in shorts overturns his motorcycle on a patch of gravel. He sustains considerable abrasions and deep lacerations of the right leg. Emergency room personnel have great difficulty trying to remove embedded gravel and dirt. Later many areas of infection develop, and dead tissue can be seen at other sites of the abrasions. A) Describe any pathogenic processes that could be occurring at the sites of injury [invasion, attachment,...

A: The Disturbing Discharge You are working in a gynecologist's office. Your first patient is a 19-year old woman who complains that she has experienced vaginal itching and a frothy greenish-white vaginal discharge with a strong odor for the past several days. When you examine her, you observe inflammation of the genital region. When you ask your patient if she is sexually active, she tells you she has had two sexual partners in the past 4 months. You swab the...

Problem: Proportion of "Cured” Cancer Patients: How Does Canada Compare with Europe? Lung cancer remains the leading cause of cancer death for both Canadian men and women, responsible for the most potential years of life lost to cancer. Lung cancer alone accounts for 28% of all cancer deaths in Canada (32%. in Quebec). Most forms of lung cancer start insidiously and produce no apparent symptoms until they are too far advanced. Consequently, the chances of being cured of lung cancer...

Lung Cancer & Smoking Case Study A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The...

You are culturing fibroblasts derived from human tissue. By using a genetic technique called CRISPR-Cas9, you knockout the gene in these cells that expresses the fumarase enzyme. To your surprise, the cells continue to respire normally. You discover that after knocking out fumarase, the cells start excreting large concentrations of the metabolite fumarate into the culture medium. The only carbon source in the culture medium that is available to feed into the TCA cycle is glucose. a) If you enrich...
