A. A diabetic high-school student went to the pharmacy to get a bottle of insulin. The pharmacist told the student to be sure to store the bottle in the refrigerator. Why? (2 points)
b. Some meats need to be tenderized, meaning that the muscle fibers need to be broken down in order to make the meat easier to chew. This can be done physically by pounding the meat with a special mallet, or it can be done chemically with a meat tenderizer, which consists of enzymes that basically do the same thing. Explain how the meat tenderizer works. (2 points)
c. Take a look at the reaction rate equation below.
Rate = k[A]2[B]3
Using this equation, what would the reaction rate be for the following set of factors? (2 points)
Rate constant = 1 10–3 (L/mol)4/s
[A] = 3 M
[B] = 2 M

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
