Scientific Method American InterContinental University Online SCIE206-1301B-12 Instructor Mamie Ware March 31‚ 2013 Scientific Method Observation: During the winter‚ you spread salt daily on your driveway to melt the snow. In the springtime‚ when the lawn begins to grow‚ you noticed that there is no grass growing for about 3 inches from the driveway. Furthermore‚ the grass seems to be growing more slowly up to 1 foot from the driveway. Question: Might grass growth be inhibited by salt

Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? The main function of cellular respiration is to generate ATP for cellular work; it is the process of harvesting chemical energy from organic fuel and converting it to ATP energy. The three stages of cell respiration include: Glycolysis‚ Citric Acid Cycle‚ and Electron Transport(Simon‚ Reece‚ & Dickery‚ 2010). • What is the role of glycolysis

Background Information: Cell Transport When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system‚ the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires energy?
