om either a 15-day-old1-old guinea pig.Data from the Experiment When you have multiple sets of data,it can be useful to plot them on the same graph for comparison. In thegraph here, each set of dots (of the same color) forms a scatter plot, inwhich every data point represents two numerical values, one for eachvariable. For each data set, a curve that best fits the points has beendrawn to make it easier to see the trends. (For additional informationabout graphs, see the Scientific Skills Review in Appendix F.)INTERPRET THE DATA1. First make sure you understand the parts of the graph. (a) Whichvariable is the independent variable-the variable controlled bythe researchers? (b) Which variable is the dependent variable-thevariable that depended on the treatment and was measured by theresearchers? (c) What do the red dots represent? (d) The blue dots?2. From the data points on the graph, construct a table of the data.Put "Incubation Time (min)" in the left column of the table.No energy input is thus required: This is passive transport. TheScientific Skills Exercise gives you an opportunity to work withlata from an experiment related to glucose transport.BioFlix® Animation: Passive TransportMBCONCEPT CHECK 7.31. How do you think a cell performing cellular respirationrids itself of the resulting CO,?2. WHAT IF? > If a Paramecium swims from a hypotonicto an isotonic environment, will its contractile vacuolebecome more active or less? Why?

The question is a conceptual question about diffusion and osmosis.

4. REDOX reactions in special organelles are like biological batteries. They involve electrons moving through a contained system, and use a build up ions on one side of a membrane to create energy. Energy carrier molecules, electron transport, ATP hydrolysis and ATP synthesis have been common terms over the past month or so. Below is an image that shows two organelles we have been focusing on, along with important membranes that can establish a proton gradient. Using the diagram, explain how chemiosmosis is established in mitochondria and chloroplasts. You must correctly name the important membrane in each organelle, and include the following words in your answer; ATP, protons/, Pi, ATP synthase, ADP, and proton-motive force.
