All of the images shown above involve mares affected by Granulosa Cell Tumors (GCTs), including one mare exhibiting stallion-like behavior and mounting another mare in standing estrus. A subset of these tumors also contain theca cells, as well as possibly other types of cells, and are more specifically referred to as Granulosa-Theca Cell Tumors (GTCTs). However, for the sake of simplicity, we will use GCT to refer to either of these ovarian tumors containing granulosa cells. From the FIVE statements below, select the FOUR (4) which are CORRECT, with respect to equine GCTs.

The pathologic changes evident in the images of equine endometrium shown below are most characteristic of which of the following conditions?

Calculate the molarity of a solution that contains [salt] moles of NaCl in [water] liters of solution at a temperature of  [deltaTf]°C.  

Antifreeze is ethylene glycol (C2H6O, M = 62.07 g/mol, Kf = 1.86 C/m). Calculate the mass of [T] moles of antifreeze. Report your answer in units of grams, but only enter your numerical answer. Remember — use three sig figs unless otherwise specified.

I, Moana Sitake, your instructor, have a favorite recipe that I use to make puff pastry dough for savory meat pies, a special treat in NewZealand.  We have special event coming up in our family and I need to make 250 meat pies for the event.  The key to success of a true European flaked puff pastry is the high-quality butter.  The recipe calls for 57 g cold, cubed European-style butter (again, I use the NZ butter, it’s the best) for the détrempe (dough) and 170 g European-style butter (82% fat or higher, NZ butter is 95% fat) for the butter block, or to fold into the dough. The recipe uses grams and milliliters (of course, everywhere but the US does, Dr. Sitake’s editorial comment) instead of cups.  This makes a 10X15 inch sheet and I can make eight 5-inch pies with one sheet of puff pastry. 1Tbsp of 93% fat butter is 14.2 grams 8 Tbsp of butter in a stick or a 1/4 pound How many pounds of butter do I need for 250 pies?   Rubric: 1 pt for correct calculation 1 pt for solving using dimensional analysis (using one continuous line) 1 pt for showing all conversion factors correctly used 1/2 pt for giving the answer in proper significant figures.
