Monday Some researchers are developing a new plant fertilizer designed to improve the growth of plants in hot, dry climates. The fertilizer was applied to 100 desert plants in a greenhouse. The average daytime temperature in the greenhouse was 90oF, and the humidity levels were low. Which is best for the researchers to do next? Compare plants that receive fertilizer to similar plants that received none. Begin selling the fertilizer Change the conditions in the greenhouse Test the fertilizer on plant adapted to cooler climates

2. Medical researchers are developing a wireless blood pressure monitoring system for use in hospitals. This system allows nurses to measure a patient’s blood pressure without awakening the patient. Which is the intended benefit of this technology? A. patients can experience pain relief B. patients will need fewer medications C. patients will not be disturbed D. patients can avoid surgery

Tuesday In an investigation about the effects of CO2 on plant height, plants are grown in several closed containers. The plants all get the same amounts of H2O and light, but the air inside has different amounts of CO2. what is the independent variable in this experiment? The number of plants in each container The amount of CO2 in each container The amount of H2O in each container The height of each plant
