"The effect of insecticide on the number of plant leaves" is the title of a table of data. A possible hypothesis for this experiment might be
A If the concentration of insecticide is followed on the product label, then the number of leaves will increase with time because insects weren't eating or damaging the leaves.
B If the number of leaves increases, then the concentration of insecticide was the recommended dose on the label.
C If the number of leaves decreases, then the recommended dosage of insecticide was doubled.
D If the concentration of insecticide is followed on the product label, then the height of the plant will increase with time because insects weren't eating or damaging the plant.

"The effect of insecticide on the number of plant leaves" is the title of a table of data. If all the data collected in the experiment were zeroes (meaning that all the plant leaves died), would you accept or reject the hypothesis in the previous question?
A Accept, because the concentration of insecticide was too strong.
B Reject, because the number of leaves decreased instead of increasing.
C Reject, because the death of all the leaves implies that maybe there was something else occurring in the experiment to affect the number of leaves instead of insect pests eating the leaves.

The experiment shown above is looking for the number of plant and animal organisms that are needed to balance the gases in an acquarium. One step in the experiment placed a snail in a solution inside test tubes #2 that were exposed to a day and night treatment. Test tube #1 only contained the solution. The solution used had a chemical in it that reacted with carbon dioxide. The solutions in test tubes #2 both turned from green to yellow at the end of the cycle indicating that carbon dioxide concentrations had increased (High level). This is because all organisms perform cellular respiration 24-7 and the waste gas from cellular respiration is carbon dioxide.

One of the lab technicans thought that a plant should be used in the test tubes to determine the amount of cellular respiration that was occurring. In this experiment a plant was put inside the test tubes #2 and exposed to a day and night cycle. The test tube solution for the plant exposed to the day cycle turned from green to blue, indicating that the carbon dioxide in the solution had all been used up. The test tube solution for the plant in the night cycle started green and turned yellowish, indicating that there was a higher concentration of carbon dioxide. The plant wasn't a good choice to prove cellular respiration in organisms because there would need to be equipment to sort out the different exchanges of gases from photosynthesis and respiration.
