3 Multiple Choice: 25. Students of a biology class ran an experiment on a type of flowering plant. Their goal was to find the optimal time in the plant s life for flowering. What time period below will provide the most flowering plants? Use Table 1-1 below to determine your answer. 5-6 days 6-7 days 7-8 days 8-9 days Table 1-1 Number of Plants Day Flowering Growth occurs through - adaptation and evolution cell division organization and reproduction stimulus and response 27. The Science of life is called - anatomy biology ecology phylogeny 28. Which of the following terms enables an organism to grow, reproduce, and carry out all other life processes? energy environment evolution experiment 29. Sean wants to research the effectiveness of sports drinks on hydration during vigorous physical activity. Where should he look to find reliable information? a survey of a football team back issues of sports magazines scientific journals on exercise physiology web sites of companies that make sports drinks 30. Which part of a compound light microscope should a student adjust to allow more light to pass through a specimen? diaphragm fine adjustment ocular lens stage

4 31. The size of the image of a cell being examined with a compound light microscope is determined by the - diaphragm and coarse adjustment light source and fine adjustment ocular lens (eyepiece) and objective lens stage and stage clips 32. Which sequence contains the correct order of steps for a student to follow to observe the internal organization of a pond water organism prepared on a wet mount slide, using a compound light microscope? (1) (2) (3) (4) 33. What is the highest magnification that can be obtained with a microscope that has a 10x eyepiece with 10x and 43x objectives? 43x 63x 430x 4300x 34. A student wanted to study the effect of temperature on algae levels in a local stream. Which items a most useful for GATHERING DATA and most appropriate for COMMUNICATING THE RESULTS of her observation? microscopes and written descriptions of weather patterns ph strips and written observations of stream water research on the internet and videotapes of water samples test tubes, thermometers, and graphs of results 35. Why should an experiment have only one variable? Each additional variable adds to the cost of the experiment. Each variable cancels the actions of another variabl If more than one variable is present, the experimenter will not know which variable caused the result. The experimenter cannot change more than one variable at a tim

5 36. What is the total magnification used to view these onion cells through this microscope set up? 10x 40x 50x 400x 37. A scientist designed an experiment to test the effect of temperature on bacterial growth. He grew three different cultures of the bacterium E. coli under three heat lamps at different temperatures. What was the independent variable in this experiment? Length of experiment Number of bacteria Reproduction rate Temperature 38. Using this tool, Anton von Leeuwenhoek was the first scientist to Use a telescope See microscopic organisms Magnify plants Observe light waves 39. The cell theory states that - all cells have nuclei that contain genetic information living organisms are composed of cells that come from preexisting cells all cells regenerate and contain the same basic structures organisms that lack certain organelles reproduce by binary fusion 40. Maintenance of the ph of human blood within a certain range is an example of - homeostasis respiration synthesis digestion 41. The diagram to the right shows an amoeba through a compound light microscop The amoeba is moving out of the highpower field of view in the direction indicated by the arrow. What should be done to center the amoeba in the field of view and focus it sharply? Move the slide to the right, and refocus with the fine adjustment knob Move the slide to the right, and refocus with the coarse adjustment knob Move the slide to the left, and refocus with the fine adjustment kno Move the slide to the left, and refocus with the coarse adjustment kno

6 42. A lab activity requires students to insert potassium hydroxide (KOH) pellets into a narrow tube to absorb carbon dioxide (CO2). Pellets of KOH are very caustic and alkaline, making them dangerous to handl Which is the safest way to put the pellets into the tube? use bare fingers to transfer the pellets handle the pellets with wet paper towels use forceps (tweezers) to transfer the pellets pour the pellets direction from the supply bottle into the tube 43. What characteristic do all living things share? The contain DNA They are made up of many parts They reproduce by mitosis They need oxygen to survive 44. Which of the following is not a characteristic that all living things share? Respond to a changing environment. Pass on information to subsequent generations. Consume energy by eating other organisms. Are highly organize 45. In an investigation designed to determine the effect of the amount of water on plant growth, two groups of equal-sized bean plants of the same species were grown under identical conditions, except for the amount of water they were given. One group was watered with 200 ml of water once a day, which the other group was watered with 400 ml once a day. After several days, the heights of the plants were measure It was determined that the plants watered with 400 ml of water once a day showed more growth. The variable in this investigation is the: Group of beans plants watered with 200 ml of water each day Type of soil the bean plants were growing in Amount of water given to the plants each day Type of bean plants used in the experiment Short Answer 46.
