please calculate the concentration in ppm (last column) for each solution

MReview | Constants | Perio Part A Describe in general terms how a steroid hormone works. Steroid hormones travel through the bloodstream and bind to cell receptors, which are on the outside of a cell. The receptors cause production within cells of "second messengers" that activate enzymes. Steroid hormones travel through the bloodstream to target tissues. Because they are lipids, they are able to pass through the cell membrane. Receptors for steroid hormones occur either in intracellular fluid or in the nucleus.

Can you please provide steps for how to answer the following? This is not a graded assignment, it's just practice questions for no credit.  The concentration of the stock glucosamine solution is 100 mM. A student took 0.5 ml of this stock solution and added it to a test tube containing 24.5 ml of water. The student then took 1 ml out of the diluted solution and added it to another test tube containing 9 ml of water. The concentration of glucosamine in the second test tube will be: a. 0.4 mM b. 0.8 mM c. 1.2 mM d. 1.6 mM e. 0.2 mM. If you took 10 ml out of a protein stock solation of 0.25 mg/ml and added it to a bottle containing 40 ml of buffer and 500 ul of cofactor. What will be the final concentration of the protein in the bottle? a. 55.5 ug/ml b. 45.5 ug/ml c. 52.5 ug/ml d. 49.5 ug/ml e. 65.5 ug/ml
