Set 6 – Lab 6: Diffusion, Osmosis, and Cell Membranes You watched a video about dialysis and how solutions can diffuse across a membrane. A solution consisting of a 10% glucose and 10% starch were used to fill dialysis tubing. The tubing was tied and sealed and placed into a beaker of deionized water (DI water).  Part 1:  Based on the initial concentrations of water inside and outside the dialysis tubing, what can you conclude about the direction of osmosis? Explain (2 pts) Part 2: The majority of one substance remained in the tubing, while there were slight traces left of the other substance that mainly diffused into the beaker. The majority of what substance remained in the bag? (1 pt.) __________ Part 3:  Which reagent supported your argument for a positive result of the substance in a higher amount that remained in the bag in Part 2?   (1 pt) ____________  

Set 9 – Lab 7: Enzymes Fill in the blanks of the reaction equation from Lab 7.  Blank #1 = Which substance was used as the reactant? Blank #2 = Which substance was used for the enzyme? Blank #3 = Which substance(s) were the result creating a final product or products? Blank #4 Extra Credit (+1): Was this reaction exergonic or endergonic?

Set 18 – Lab 9: Fermentation Part 1: Which type of respiration was occurring during the first 15 min of this experiment? Part 2: Which type of respiration was occurring during the second 15 min of this experiment?

Sales at East Corporation declined from $100,000 to $80,000, while net operating income declined by 300%. Given these data, the company must have had an operating leverage of:

Last year, Tinklenberg Corporation’s variable costing net operating income was $52,400 and its inventory decreased by 1,400 units. Fixed manufacturing overhead cost was $8 per unit for both units in beginning and in ending inventory. What was the absorption costing net operating income last year?

Thomason Corporation has provided the following contribution format income statement. Assume that the following information is within the relevant range. Sales (1,000 units)                                                          $40,000Variable expenses                                                           30,000Contribution margin                                                        10,000Fixed expenses                                                                 7,000Net operating income                                                    $3,000If the variable cost per unit increases by $1, spending on advertising increases by $2,000, and unit sales increase by 50 units, the net operating income would be closest to:
