Direction: Create your own safety protocols (5) before, during and after camping to prevent possible health risk. Write your answer after each number. 1. 2. 3. 4. 5. Performance Task 1: Quezon Province Camp Sites! Direction: Choose a camping site within Quezon Prowince and do some rescarch about the place by using the guide statements below. There are two options to submit this activity. But you can choose ONE that suits to your interest and capability. Encircle the letter of your chosen task. Option A. Create a power point or video presentation promoting the camp site and upload it to the OFFICIAL GC with subject teacher. Consider the attached rubrics below in making your output. Option B. Create a three-fold brochure promoting the camp site you hase chosen and submit it to your subject teacher in school. Consider the attached rubrics below in making your output.

Worksheet - Lab 5: Respiration and Photosynthesis (25 points) Photosynthesis and Cellular Respiration Lab Report You should be sure to do your own work and type your answers using complete sentences. Please use the lab manual graph paper when indicated. Activity 1: Measuring CO2 Production in Yeast 1. What is your hypothesis for this experiment? 2. Table sugar is composed of which monosaccharides? What is the concentration of each type of monosaccharide in table sugar? 3. Lactose is composed of which monosaccharides? What is the concentration of each type of monosaccharide in lactose? 4. In this experiment, what is the independent variable? 5. In this experiment, what is the dependent variable? 6. In this experiment, what is the control treatment? 7. Please use the graph paper provided to plot the results of your experiment (i.e., balloon circumference over time for the four treatments). Do not forget to provide a figure title as well as axis labels. Activity 2: Measuring CO2 Use by Elodea 1. Which set of photosynthesis reactions was being directly measured in this experiment? 2. What other molecules are necessary for that set of reactions? 3. Given what you know about the reactions of photosynthesis, why would the color of the dye not change from yellow to red in the dark? 4. In order for the Elodea leaves to photosynthesize, they need light and both water and carbon dioxide. Activity 3: Oxygen Production in Elodea 1. Write the complete photosynthesis equation, being careful to obey the first law of thermodynamics. 2. Which set of photosynthesis reactions was being directly measured in this experiment? 3. What other molecules are necessary for that set of reactions? 4. Why was sodium bicarbonate used in this experiment? Conclusions: 1. Which main groups of organisms undergo cellular respiration? 2. Which main groups of organisms undergo photosynthesis?

Various cost-behavior patterns. (CPA, adapted) Select the graph that matches the numbered manufacturing cost data (requirements 1-9). Indicate by letter which graph best fits the situation or item described. The vertical axes of the graphs represent total cost, and the horizontal axes represent units produced during a calendar year. In each case, the zero point of dollars and production is at the intersection of the two axes. The graphs may be used more than once. 1. Annual depreciation of equipment, where the amount of depreciation charged is computed by the machine-hours method. 2. Electricity bill-a flat fixed charge, plus a variable cost after a certain number of kilowatt-hours are used, in which the quantity of kilowatt-hours used varies proportionately with quantity of units produced. 3. City water bill, which is computed as follows: The gallons of water used vary proportionately with the quantity of production output. 4. cost of direct materials, where direct material cost per unit produced decreases with each pound of material used (for example, if 1 pound is used, the cost is $\$ 10$; if 2 pounds are used, the cost is $\$ 19.98$; if 3 pounds are used, the cost is $\$ 29.94$, with a minimum cost per unit of $\$ 9.20$ 5. Annual depreciation of equipment, where the amount is computed by the straight-line method. When the depreciation schedule was prepared, it was anticipated that the obsolescence factor would be greater than the wear-and-tear factor. 6. Rent on a manufacturing plant donated by the city, where the agreement calls for a fixed-fee payment unless 200,000 labor-hours are worked, in which case no rent is paid. 7. Salaries of repair personnel, where one person is needed for every 1,000 machine-hours or less (that is, 0 to 1,000 hours requires one person, 1,001 to 2,000 hours requires two people, and so onl. 8. cost of direct materials used (assume no quantity discounts). 9. Rent on a manufacturing plant donated by the county, where the agreement calls for rent of $\$ 100,000$ to be reduced by $\$ 1$ for each direct manufacturing labor-hour worked in excess of 200,000 hours, but a minimum rental fee of $\$ 20,000$ must be paid.
You are employed at a biotech company, working on a new drug, named ZZZ, which is a sleep aide. Your boss wants to know how this compound moves into red blood cells, and what its concentration will be in red blood cells. He has provided you with plenty of samples of drug ZZZ, and you have the means to measure its concentration (mmol l-1) inside and outside red blood cells, as well as the concentration of any metabolites of drug ZZZ (in case the body can turn ZZZ into other things). He has now asked you for a protocol, and predictions of how the data will come out depending on how ZZZ crosses the red blood cell membrane. Drug ZZZ may move into red blood cells by simple diffusion through the lipid bilayer. If so, graph the concentration of drug ZZZ inside and outside of the red blood cell vs. time. Assume that when you drop the red blood cells into the bathing solution that they initially contain zero ZZZ. (2 pts). After five minutes, the concentration of drug ZZZ in the red blood cells is 7 mmoles l-1. What is the rate of entry of drug ZZZ into the red blood cells in units of moles min-1 red blood cell-1 during the first five minutes after placing the red blood cells into the bathing solution. Assume that each red blood cell occupies about 1 x 10-13 liters. Show your work. (2 pts). Graph rate of entry of ZZZ into the red blood cells (moles min-1 red blood cell-1) vs. the concentration of ZZZ in the bathing solution, assuming ZZZ enters the red blood cells by diffusion. The point is to know the correct shape of the graph. (1 pt). Drug ZZZ may enter red blood cells by protein-facilitated diffusion. Graph the rate of entry of drug ZZZ into the red blood cells vs. the concentration of drug ZZZ in the bathing solution if ZZZ enters the red blood cell by protein-facilitated diffusion. The important point is the shape fo the plot. Explain your answer (2 pts) Describe the effect of a blocker of cellular ATP production (e.g. anoxia plus sodium fluoride) on transport rate of ZZZ if transport occurs by active transport, simple diffusion and protein-mediated diffusion.
