A client calls. “My Schnauzer just ate 3 pieces of Russel Stover candy. They are about 1 ounce each. I heard chocolate is toxic to dogs. Do I need to worry? My dog weighs 20 lbs, I know she is overweight. I have tried to put her on a diet but she keeps stealing food from the other dogs! She is about 5 years old.” What is your biggest concern.

Is the bolded statement TRUE or FALSE? Tertiary and quaternary structures are the final levels of protein structural hierarchy. Which of the following statement(s) is (are) true given these topics? 51. Subunits are held together by non-covalent forces to make up the quaternary structure of a protein. 52. The hydrophobic core of a globular protein forms when two subunits with hydrophobic interfaces come together. 53. Non-covalent interactions between amino acids side chains within a single tertiary structure only form between amino acids close to each other in the primary structure. 54. Quaternary structures can consist of no more than 7-subunits.55. The quaternary structure of a protein can be formed by subunits of identical primary structure or differing primary structures.

Smith is a weld inspector at a shipyard. He knows from keeping track of good and substandard welds that for the afternoon shift 5% of all welds done will be substandard. If Smith checks 300 of the 7500 welds completed that shift, find the probability that he will find less than 20 substandard welds?
