Microbiology Osmosis Lab Report Lab Experiment 9 Osmosis Introduction Kinetic energy is present in cells and its this energy that causes the cells to move. Diffusion causes cells to move from a higher concentration to a lower concentration. Osmosis is a diffusion that allows movement of water through a selectively permeable membrane. Osmosis occurs until it reaches equilibrium‚ or when the concentration on each side is the same. This is called an isotonic solution. A solution with differing

Also the sunlight beaming on the trees‚ with no water it causes them to die. - ------------------------------------------------------------------------- Question 3 Limestone‚ an underlying material for many soils‚ dissolves and corrodes when exposed to high concentrations of hydrogen ions. How is this information important in understanding the effects of acid precipitation? Acid rain can cause the loss

Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup

EXPERIMENT 1 PART 1 Procedure: 1. The epidermal layer of an onion is scaled off carefully and placed on a drop of distilled water on the glass slide; 2. The glass slide is slowly lowered down on the epidermal layer using the needle; 3. The onion cells are examined through the microscope; 4. The structure of the onion cells is drawn as observed under the microscope. Results & Observations: In the hypotonic solution the water will move from the solution to the onion cells

Ryan Stephens EN1320 04/13/2015 Rhetorical Analysis of “I have a dream speech” The main point of Dr. Kings speech was that an injustice had been done to the black people. They were promised freedom from the emancipation proclamation‚ and up to that point they still were not free. They were segregated and treated like second class citizens. Were they supposed to just sit down and let white men at that time humiliate them‚ beat them‚ bomb their houses‚ and strip them of human dignity
