A student investigated the effect of radiation on the d.) According to your graph, what conclusions can be germination of bean seeds. He thought that exposure to made about whether ants dig more tunnels at night or radiation would limit the seeds ability to germinate during the day? State your conclusion below. (grow) much like ultraviolet light causing skin cancer. Three hundred seeds were soaked in distilled water for 3.) Directions: Look at the graph below and answer the one hour. They were then divided into three groups. following questions. One group was placed in a microwave oven on high for 3 seconds. Another group was microwaved on high for 6 seconds. The last group was not microwaved. The seeds were then planted in 3 separate boxes and given the same amount of water. The boxes were placed in a location with a constant temperature of approximately 27 degrees Celcius. Each day for two weeks the number of seeds that germinated each group was recorded. a.) Write a problem and hypothesis for this experiment. b.) What is the independent and dependent variable? c.) What is the control? d.) What remained constant. 2.) Directions: Read the following experiment. Determine the control, independent and dependent a.) What is the difference between male and female variable. Then create a graph on the graph paper students in room 301? provided to represent the data. b.) Which classroom has more females than males? A student investigated the effect of fertilizer on the growth of bean plants. She thought that the fertilizer c.) Which classroom has the most males compared to would provide extra nutrients and make plants grow females? faster. Thirty bean seeds were divided into 2 groups and planted in different boxes. All seeds germinated after 12 d.) Which rooms have more males than females? days. The boxes were given the same amount of water and the same amount of light. They were measured for 4.) Write an example for the following: 7 days. Box A received fertilizer and box B did not receive fertilizer.

Put the following biological hierarchy in order from smallest to largest: Organ, Organ System, Cell, Tissue, Organism 18.) A teacher demonstrates a drop of glue that quickly consumes pieces of wood and moves around rapidly in a petri-dish responding to other glue drops. Several students in the class are convinced that this glue drop is alive because it is able to move, consume food and respond to stimuli. How could you convince them that this glue drop is not considered a living thing?
