You are researching a bacterial transcriptome when you discover what appears to be an uncharacterized gene (RNA sequence that aligns to the genome in a place with no known gene). About 10 bases upstream of this suspected gene, you find a typical sigma (σ) binding site. In order to study the function of this suspected gene, you use targeted mutagenesis to delete the sigma binding site. What is the most likely outcome of this mutation?

At what age does a pediatric skull have approximately the same tissue density as an adult skull?

Determine if the relation shown is a function. Define the domain and range. Make sure to use the appropriate notation. Use two lowercase ‘o’s for infinity. It will look like oo. Be sure to use the appropriate notation, it matters! {(4, 5), (-6, 5), (7, 10)} Function? : [fun] {yes or no} Domain: [dom] Range: [ran]

Extra credit (1 point) You are an RN working in the hospital.  Your shift is one that requires you to work overnight.  You discover that your thermometer on your dynamap isn’t functional.  What is your first thought?  (Btw, it’s 2 a.m.)  Pick all the answers that you feel demonstrate responsibility, maturity, and an ability to utilize higher-level thinking.   I should call the biomedical engineer that’s on call.  My stuff isn’t working and it’s his/her job to make sure that it is, regardless of the time. I wonder what’s wrong?   Should I check to see if it’s plugged in?  Or maybe in need of batteries? Maybe I should find a different device until this one can be fixed, that way I can get on with my job. I’ll just hide in the breakroom till my shift is over.

True or False? Blood only consists of cells and a ground substance. Blood never has fibers. (If you think your answer needs explanation, I’ve given you extra space for that.  Otherwise, a simple true or false is sufficient.)

The ______ wraps around the stomach, small intestine, and large intestine.
