N2Microbes

Hello, I am trying to determine the identification of an unknown. My boiling point is some where between 129- 134.7 Celsius. My Refractive index was 1.392 after being corrected for room temperature. It was not soluble and water and was less dense. MY IR spectroscopy is attached below please help I have been unable to identify this compound for about 4.5 hours now. Best regards, N2Microbes also on another note it smells like bananas

I have started searching for phages that infect S. pyogenes. My group and I have had a few failed attempts first we tried finding the lytic phages in soil it became apparent to me that was a very amatuer idea since strep isn't really a soil bacteria. Then we went on to try and find them in our mouths, we had plenty of S. pyogenes growth but no phages. I looked up some articles on strep phages and I discovered that the environment in the mouth is a horrible environment for lytic phages. I have now come to this forum hoping that I can find a virologist or someone that can help point me in the direction of finding these elusive phages.

Can somebody help me understand this? I understand class 1 and 2 MHC molecules I am getting confused when they are being named like K^b and IAa^b help please?

Is this how you do it and is this the correct answer? Since man has only one X chromosome, she must have one X defective and one X normal (from mother). In 30% of cell divisions the chromosomes recombine and form two defective X chromosomes (each for other disease, but they ask for normal kid, so any of these chromosomes will be ruled out). In the other 70% cases the chromosome will be defective in 50% and normal in 50%, i.e. 35% of total cases. Thus 4.) is the right answer.

Genes for color blindness and hemophilia are linked on the X-chromosome in humans with a recombination frequency of 30%. A woman whose father was a color blind hemophiliac and mother was normal with no history of color blindness and hemophilia wants to have children. The prospective father is normal with no history of either colorblindness or hemophilia in his family. what is the probability that she will have a normal child? 1.) 0.70 2.) 0.675 3.) 0.50 4.) 0.35 5.) 0.30 6.) 0.15 I have to turn it in by 5:45 any help is greatly appreciated
