the figure shows a signal transduction pathway involving two proteins found in the cytoplasm?JAK and STAT. based on this figure, what are the roles of JAK and STAT in this pathway?

a) JAK is a protein kinase and STAT is a G protein

b) JAK is a G protein and STAT is a transcription factor

c) JAK is a G protein and STAT is adenylyl cyclase

d) JAK is a transcription factor and STAT is a GTPase

e) JAK is a protein kinase and STAT is a transcription factor

\f2. Each week, a computer store sells an average of 100 sets of external hard drive. Weekly demand is normally distributed with a standard deviation of 4 sets. The store orders hard drive from a regional distributor. The lead time for delivery is random with mean 2 weeks and stan deviation 1 week. The cost of placing each order is $100, and the weekly cost of holding one of hard drive in inventory is $2. The per-unit stockout cost is assumed to be $4. The store is willing to assume that all demand is back-logged. (a) (5) Determine a good size of order. (b) (10) Determine a good reorder point. (c) (5) What is the safety stock level? (Critical point for standard normal distribution: zo.5 = 0.0, zo.35 = 0.1, zo.6 = 0.2, zo.65 = 0.3, 20 0.5, 20.75 = 0.6, Zo.8 = 0.8, Zo.85 = 1.0, 20.9 = 1.2, zo.95 = 1.6, 20.99 = 2.3, 20.939 = 3.0.
