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 .…

A scientist is studying the effect a new fertilizer has on the root growth of bean seedlings. Three groups of plants are grown in the same location in a greenhouse, each receiving the same amount of sunlight and water every day. The scientist measures the length of the roots for each plant every day. The scientist then calculates the mean for each group for five days. The results are shown in the following table. Fertilizer Experiment Data Table A What is the independent variable in this experiment?

Mina is testing different types of heat lamps to determine which type is most effective for growing strawberry bushes. She purchases two different types of lamps from a local store. Mina applies brand A to one area of the yard and brand B to another area of the yard, both of which receive full sunlight. She waters the area with brand B daily; she waters the area with brand A every other day. At the end of the study, Mina concludes brand B is more effective in growing strawberry bushes. Mina's conclusion valid? Explain why or why not.
