Part 1 Questions 1) What sort of environment (hypotonic‚ hypertonic‚ isotonic) did the extra fertilizer create around the roots of the corn? The extra fertilizer created hypertonic environment. 2) Keeping in mind your answer to the previous question‚ what do you believe caused the corn plants to wilt and eventually die? - I believe that the extra fertilizer having a higher concentration than the first round of fertilizer was not a good environment for the corn to try and survive in. 3)

Solution A homogeneous mixture of two or more substances with each substance retaining its own chemical identity. Solute – substance being dissolved. Solvent – liquid water. General Properties of a Solution 1. Contains 2 or more components. 2. Has variable composition. 3. Properties change as the ratio of solute to solvent is changed. 4. Dissolved solutes are present as individual particles. 5. Solutes remain uniformly distributed and will not settle out with time. 6. Solute

The cell membrane regulates and controls what kind of molecules ______ move in & out of the cell. 2. When molecules spread from an area of high to low concentration‚ it is called _Diffusion_____. 3. As molecules diffuse‚ they create a _concentration gradient_____
Premium Concentration Osmosis Solution
concentration of solutes relative to one another __B__ the movement of molecules across a selectively permeable membrane with the aid of specialized transport proteins a. diffusion b. facilitated diffusion c. osmosis d. active transport e. hypotonic f. isotonic g. hypertonic 2. What is the main difference between simple diffusion and facilitated diffusion? Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated Diffusion

Be sure to refer to the solutions as being hypotonic‚ hypertonic and isotonic. The plasma membranes are made up of proteins that form pores and channels‚ cholesterol to provide membrane stability and carbohydrate molecules for cell recognition. The most abundant component found in the plasma membrane is the

Diffusion & Osmosis: Introduction: This experiment was performed to demonstrate the process of osmosis and to show visible as well as quantitative evidence proving that osmosis occurred. Through the tasks of determining the percent concentrations in two different solutions‚ we were studying the process of osmosis. Osmosis is the best way to perform this experiment because as we went through the experiment‚ the weight of the beaker/dialysis tubing changed and the only logical explanation was

Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and
