Michael wanted to see what kitchen cleaner worked best for cleaning her counters he used Lysol, Clorox, Pinesol, and just water. for each cleaner he put 5mm of grape juice on the counter sprayed the cleaner and wiped it with one paper towel what is the Independant Variable, Dependent Variable, Control, and Constants

Following is the data and notice that it is a terrible idea to culture hMSCs longer than 10 days. You’re strongly Days # cells0 50001 75002 125003 125004 218005 287006 530007 1143008 1653009 19200010 19200011 11680012 8950013 8830014 78300 Part1 You are working for a start-up that is pursuing a clinical trial. The trial involves grafting hMSCs intopatients suffering from interveterbral disc disease using a degradable polymer scaffold. You are going to 3Dprint a porous cylindrical scaffold that is 2 cm in radius and 1 cm in height (matching the dimensions of adegenerated disc). Assume a porosity of 50%. You will fill available volume of the scaffold with hMSCs at adensity of 1 million cells per cm3. Based on the data above, what starting number of cells will you use andhow long will it take you to get enough cells for the trial? Part2The trial is a failure (patients did not report any reduction in back pain). Your team wants to try againusing 85% hMSCs and 15% nucleus pulposus cells .…
