What would the control group be? What would the experimental group be? II. Experiment 2 In this experiment, students will: A. determine if tobacco extract has an effect on the rat Cigarette smoke has been found to have ciliotoxic effects. In this investigate whether th concentrations of extracts from chewing tobacco. The m e rate of food vacuole form ation is altered with exposure to varying added to cells is 50 microl fume hood by your IA. aximum volume of tobacco extract to be liters. Tobacco extract is highly toxie and will be added under the (4) If this extract inhibits cilia, what implications does this have for the functioning of human airways? (5) Propose a hypothesis of the effect of tobacco extract on vacuole formation in Tetrahymena. ?. ??: b. Ha: Procedure: Follow the same basic procedure as Experiment 1 but with three groups. Your final volume of cells plus ink will be 500ul with a 1:1 ration of cells and ink. (6) What is the control group? (7) Experimental groups? (8) Write a detailed list of your actual procedure.Explanation / Answer
4) Cilia present in the airways clears the mucus and dirt present in the airways and helps in respiration. When cilia are affected, thee functions are affected.
5) a) Ho (Null hypothesis): Tobacco extract has no effect on the rate of vacuole formation
b) Ha (Alternate hypothesis): Tobacco extract has an effect on the rate of vacuole formation
6) Control group should be similar to experimental group except for the exposure of tobacco extract
7) The group which gets exposed to tobacco extract will be the experimentalgroup.
8) The tobacco extract should be added in increasing concentrations on the experimental group and the rate of vacuole formation is observed.
