2) Isotonic solution equilibrium 3) Hypertonic High [solutes] in ECF Oct 199:29 AM 1 Physiology Ch 3 Types of Solutions.notebook October 22‚ 2013 Hypotonic Low [solutes] in ECF In this situation‚ water wants to move from the ECF to the inside of the cell since there is a lower [H2O] inside than out. Particles (solutes) want to move out of the cell to the ECF since there is a lower [solute] outside the cell. Hypertonic High [solutes] in ECF In this situation

It ’s So Clichéd "She sat down to write her paper without batting an eyelash." This sentence contains an example of what is called an idiom. Idioms are individual forms of expression specific to one language. They can be thought of as a group of two or more words that together mean something different from the literal meaning of the individual words. "Without batting an eyelash" means to be passive‚ or show no interest in an event or situation. This phrase first appeared in the early 1900 ’s."Batting"

concentration of solute (higher concentration of water) than inside the cell. This is correspondent with this lab because the vinegar has a higher concentration of water than the egg. This clarifies why the egg increases in size. In contrast‚ a hypertonic solution occurs when the solution has a higher percentage of solute (lower concentration of water) outside the cell. This would cause the egg to shrivel and decrease in size. Day four Egg volume: 2 oz. Remaining Corn syrup: 8 oz. Now that
Premium Osmosis Concentration Solution
Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

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 follows

Predict the effect on a red blood cell (crenation‚ hemolysis‚ or none) that the following solutions would have: Sample 2% glucose solution 2% NaCl solution Pure H2O Isotonic/hypotonic/hypertonic? Crenation/hemolysis/none? hypotonic hypertonic hypotonic hemolysis crenation hemolysis 5. (6) Describe how an artificial kidney separates waste products

solution for further analysis. Ultimately‚ the egg in distilled water exhibited an increase in weight while the egg in salt water was the opposite; a decrease in weight. This conclusion proves that water diffusion occurs from a hypotonic solution to a hypertonic solution. Osmosis in a plant cell was tested by comparing an Elodea cell in pond‚ distilled‚ and salt water. After obtaining samples of the Elodea cell and preparing a wet mount of each leaf using all three types of water‚ observations of

weighed before and after being put in the solutions. The zero and ten percent solutions are hypotonic‚ so the eggs should gain weight. The twenty percent solution is isotonic and the weight should primarily stay the same. The forty percent solution is hypertonic‚ so the weight should decrease. (Muller) Experimental Procedure Eight eggs are placed in a medium glass bowl and covered in vinegar. (Although‚ we only need four eggs extras are made in the case some of them break.) The bowl is drained after
