ENZYME LAB REPORT 1. In your own words‚ define objective qualitative and objective quantitative data. DO NOT USE EXAMPLES AS YOUR SOLE DEFINITION. (3) There are two different types of information that can be obtained from research. The types of information that can be obtained are quantitative and qualitative data. Research results are considered qualitative when the results can be answered with a simple statement of yes or no. Qualitative data does not attempt to give a numerical value; instead

Cell membranes will allow small molecules like oxygen‚ water‚ carbon dioxide‚ ammonia‚ glucose‚ amino acids‚ etc.‚ to pass through. Cell membranes will not allow larger molecules like sucrose‚ starch‚ protein‚ etc.‚ to pass through. Problem Statement(s): What is the movement of material

energy‚ the molecules go down a concentration gradient. Active transport is the opposite it uses ATPase for energy‚ and molecules move against a concentration gradient. Prediction: When the potato cylinder is placed in a high water potential sucrose solution I think it will increase in mass‚ and length. This is because the solution has a higher water potential than the cells in the cylinder‚ water molecules will travel from a high water potential (The solution) to a low water potential (The potato

Compare and contrast xylem tissue and phloem tissue‚ including their respective structures and functions. The stems and roots of plants contain two separate transport systems; xylem vessels and phloem tubes‚ of which neither transport oxygen as it is transported to cells by diffusion. The network of xylem vessels transports water and mineral ions from the roots to all other parts of the plant whereas phloem tubes transport food made in the leaves to all other parts of the plant. In the stems

Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

The most important simple carbohydrate is glucose. It is found as a major component of other carbohydrates. For example‚ maltose is a carbohydrate composed of two glucose units. Lactose (milk sugar) contains one glucose unit and one galactose unit‚ sucrose (table sugar) contains one glucose unit and one fructose unit‚ and maltose (malt sugar) contains two glucose units. Each of these disaccharides is composed of two monosaccharides connected to each other with a glycosidic (ether) bond.

area of high concentration to low concentration (Biological 21). With this knowledge we tried to recreate diffusion for students to understand the process. The dialysis bags represented our selectively permeable membrane with the fluid inside it‚ sucrose. How much of the substance moves from the cup to the bag quickly depends on the temperature of the substance. The class used four different temperatures to measure the rate of diffusion. I thought that the rate of diffusion would increase as temperature
