B) environmental conditions holding constant through time. C) cells having enough water to survive. D) plants and animals needing energy sources. E) an organism maintaining nearly constant internal conditions. 19) What statement deals with an aspect of experimentation but with the incorrect explanation? A) The larger the sample size, the more meaningful the results. B) The smaller the sample size, the more meaningful the results. C) A control group is an untreated group and provides a basis for comparison. D) It is important to standardize aspects of an experiment that might affect the outcome, other than the independent variable. E) All answers are correct. You perform an experiment in which you take 16 pots of strawberry plants and give half of them 1 gram of ammonium nitrate per liter of water and the other half receive only water. Each group is then split in half again, and exposed to either 8 or 16 hours of light each day. You mon itor the height of the plants for 4 weeks. You observe that plants grown in ammonium nitrate and 16 hours of light grow taller than no ammonium nitrate and 8 hours of light. 20) Which of the following is/are independent variable(s) in this experiment? A) amount of ammonium nitrate and light B) amount of water C) amount of carbon dioxide D) height of the plants and amount of light E) height of the plants 21) Which of the following is/are dependent variable(s) in this experiment? A) amount of ammonium nitrate and light B) amount of carbon dioxide C) amount of water D) height of the plants E) height of the plants and amount of light 22) In this experiment, the size of the pot is A) an independent variable. B) a dependent variable. C) a standardized variable. D) a placebo. E) a control.
