community service organization that I chose was High Desert Kidney Hope. This organization is there to help the people that have kidney disease. They don’t only help the person with the disease but the family as well. Their mission statement is “Our Mission is to improve the quality of life for kidney patients and their families both through individual grants to meet basic needs as well as through educating the High Desert community about kidney disease and the needs of these individuals. We are residents

Introduction: The objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this

Martina Oganesyan Title of investigation: The effect of solute concentration on osmosis in potatoes. Research question: What is the solute concentration of a potato? Hypothesis: Osmosis is the movement of water across the membrane from an area of high concentration to an area of low concentration. The osmosis continues until the solute concentrations are equal in both areas. In this experiment‚ we put pieces of potatoes into test tubes with sugar solutions of different concentrations and leave

Tiffany Parker Mr. Taylor Biology 6th period 2/12/15 Gummy Bear Osmosis Lab Report Purpose: The purpose of this lab is to measure the amount of Osmosis in different types of solutions and to see how a cell would react in different types of solutions. Hypothesis: My hypothesis for this experiment is that the Gummy bear will absorb more of the plain tap and sugar water and the salt water will shrink the gummy Procedure: Materials- 3 clear cups‚ one spoon‚ 3 gummy bears‚ timer‚ tap water‚ salt‚ sugar

Title: The effect of temperature on beet cell membranes. Introduction: 1. Eukaryotic cells are much more intricate than prokaryotic cells. The first thing observed is the assortment of structures in the cytoplasm. The fluid filled region between the nucleus and the plasma membrane. These structures along with the nucleus are the organelles‚ each having a specific function in the cell. The organelles are by membranes divided in proficient sections .The plant cell is made up of a rigid thick wall

Because we synthesized the two most common kidney stones‚ calcium oxalate and calcium phosphate‚ we will focus on those two in the discussion of formation‚ treatment‚ and prevention. Calcium stones like calcium oxalate and calcium phosphate stones form when urine is “supersaturated with the constituent ions that comprise the stone” (Figge). This means‚ when urine is supersaturated with calcium and oxalate ion that type of stone is more likely to form. This supersaturation results from the ionic activity

Printing A Human Kidney Have you ever thought that printing something off a 3D printer could go inside your body and work like it had belonged there? For Anthony Atala this is his goal. Anthony Atala is not any average practicing surgeon. He is the director at Wake Forest Institute for regenerative medicine‚ which is not an easy field to be in. He is making the way for regenerative medicine‚ a more practical idea for the future. Atala has done hundreds of regenerative surgeries and has helped so

Experiment for the measurement of carbon dioxide and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces

VII. Conclusion The hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass
