E) producers. 5) You are sorting cards with pictures of organisms and their descriptions into groups. You would place the card with an osprey and the description "organisms that obtain energy by consuming other organisms" with cards for other A) autotro phs. B) plants. C) heterotrophs. D) producers. E) photosynthesizers. 2 6) If you observed a newly discovered 'thing' and tried to decide if it might be alive, what would be the weakest distinction for life? A) homeostasis B) movement C) structural organization D) evolution E) energy use 7) The four kingdoms included in the domain Eukarya are A) Bacteria, Fungi, Plantae, and Animalia.

D) It does not apply to problems encountered in everyday life. E) It enables the testing of ideas. 10) Which statement about a hypothesis is incorrect? A) It can be proven true. B) It can be proven false. C) It is a tentative explanation. D) It is based on previous knowledge. E) It must be testable to be useful. 11) In a scientific experiment, the investigator manipulates the variable(s) to determine whether it causes another variable to change. A) standardized B) control group C) dependent D) independent E) control group and standardized 3 12) In a scientific experiment, the investigator measures the response of the variable(s). A) independent B) dependent C) control group D) standardized E) dependent and independent 13) Which of the following is not a "control" in an experimental procedure? A) a placebo B) a known standard of comparison C) a normal group D) an experimental group E) a "zero" -value group 14) A theory differs from a hypothesis in that a theory A) has more supportive evidence than a hypothesis. B) is broader in scope than a hypothesis. C) has predictive power. D) ties together many existing observations. E) All answers are correct. 15) A structure consisting of tissues organized to carry out a specific function defines a(n) A) organ. B) cell. C) population. D) atom. E) molecule. 16) In cleaning up after lab, you have to sort cards into boxes. You would put all of the below cards into a box marked "ecosystem" except A) community. B) biosphere. C) populations. D) organisms. E) nonliving environmental components. 17) Asexual reproduction differs from sexual reproduction in that A) asexual reproduction produces genetically diverse offspring. B) asexual reproduction utilizes DNA from two parents to code for traits in offspring. C) asexual reproduction occurs only in plants. D) asexual reproduction produces offspring containing DNA from only one parent. E) asexual reproduction only occurs in animals. 4 18) If you wanted to demonstrate homeostasis to a friend, you could use as an example A) a population changing over time. 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.
