Plant physiology:

Greenhouse producers often supplement the atmospheres in their facilities with extra CO2. This addition increases plant growth, leading to more rapid plant production for sale. Describe (1) how this supplemental CO2 benefits the physiology of photosynthesis and growth and (2) what drawbacks the plant might face upon transplanting to a homeowner's garden.

Question 4: Capacity Planning [15] The diagram below represents a simplified version of the steel production process at a steel mill and the capacity of each operation in tonnes per day (tpd). The outputs from iron ore processing, limestone processing, and coking coal oven need to be combined in a ratio of 4:1:2 into the blast furnace. Output of blast furnace equals the output of iron ore processing; limestone and coke are only for purifying and burning. The outputs from the blast furnace and recycled steel need to be combined in a ratio of 2:1 for the oxygen furnace. Output of oxygen furnace = Output of blast furnace + Output of recycled steel. The remaining processes have a ratio of 1:1 with their downstream process.

Calculate the daily capacity of the production process and identify the bottleneck. b. If the capacity of the bottleneck in part a is increased by 50 percent, what is the new daily capacity and bottleneck? C. What further improvements are needed to bring plant production to 2,700 tpd?The table below gives supply and demand of the revised textbook example for the Pear Disk Drive Corporation.

Wonder Widgets Inc. has 3 plants producing their De-lux Wonder Widget (DWW). Plant A produces 75% of all DWW, plant B 20%, and plant C the remaining 5%. 6% of Plant A's production is defective, 5% of plant B's production is defective, and 1% of plant C's production is defective. (a) What percent of the total production of DWW is defective? (b) if a DWW is defective, what is the probability that it was produced in plant A
