cell culture technique

You trypsinize a T75 flask of CHO cells and resuspend your cells with media (15mL total). You determine your cell suspension contains 5 x 106 cells/ml. Howmany mLs of cells/media will you need to subculture a new flask containing: a.50 mL of medium at a final concentration of 1.5 x 105 cells/mL? b.1...

respiration of human body

The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day. The a...

reproductive sytem

The reproductive system may seem a bit isolated from other body systems in that its purpose is to create new life, not just maintain existing life. But there are significant relationships between the reproductive system and other body systems. Name three organ systems that the reproductive system es...

single bacterium

Is it possible that some colonies are derived directly from more than a single bacterium (that is a single cell not strain) taken from the liquid culture? State why

CFU

Following a serial dilution and spread plate experiment, a student counted the following number of colonies on nutrient agar plates inoculated with 100 l of respective dilutions from an original broth culture of E. coli. 10-5 = Too many to count (TMTC) colonies 10-6 = 248 colonies 10-7 = 33 colonies...
