Essay on Osmosis Investigation

Section 1: Gather the following information from field research while in the Phase 3 lab environment. Notice that each site you visit has a distinctly different surface, which could affect runoff.

The purpose of this experiment is to find out which brand of paper towel, Decorator or

4. After I added the drop that caused the water to flow over, I recorded how many drops stayed on the penny, and I then dried the penny with a paper towel.

A system is Material moving most stable when it has reached equilibrium. A out of the cell system will tend to go to equilibrium (lowest, accessible energy state) in the absence of added energy (Figure 2).

The reasoning behind this experiment is the examine whether the rate of osmosis is changed due to a change in temperature. It was hypothesized that the rate of osmosis will increase as the temperature of the sucrose is increased. The rate of osmosis was tested by using the different jars full of different temperate water and testing how high the water rose on an osmometer over a span of 20 minutes. An osmometer is a tool used to measure rates of osmosis. The different temperatures tested on a sucrose solution were 5 degrees Celsius, 20 degrees Celsius, and 37 degrees Celsius. Rates of osmosis were higher in the hot water than in the cold water and control. The results showed that the rate of osmosis increased as the temperature increased, henceforth the hypothesis was supported. In conclusion, the experiment showed how changes in temperature affect the rate of osmosis.

6. Now get all 6 of the pipe cleaners that are 21 centimeters in length and place 3 on the upper and lower side. Tape it on now. Not on the foil, but taped and attached to the side of it.

Table 1, shows the average change in mass and average rate of osmosis of the egg after it had been soaking for ten minutes in the distilled water, 1%, 2%, 5% and 10% Sodium Chloride solutions. The table also shows the SEM for each of the averages. All of the averages show that as the salt concentration increases from 0% to 2%, the rate of change in mass decreases. From the 5% salt concentration to 10%, the rate of change in mass begins to increase. This indicates that somewhere between 2% and 5%, an isotonic environment was reached. This is all shown in the results, as the average rate of osmosis in the egg after being submerged in the distilled water is 0.105 g/min, the average rate of osmosis after being submerged in the 1% solution is

4. Take a piece of dialysis(as cut earlier), find the mass of the dialysis, and the zero out the scale on

Water is essential for life as we know it on earth. It is used by plants

The movie Osmosis Jones is a about a white cell that attempts to keep under control of the body by fighting any unknown antibodies. Most of the film takes place inside of Frank’s body in which it traces an unhealthy virus that almost lead frank to his death due to his unhealthy habits. Mayor Phlegmming in charge of immunity was being reckless with Frank’s body by not clearing properly the body’s infections, and consumptions, leading Osmosis into taking charge to help Frank fight off any sicknesses.

The Adelaide Desalination Project (ADP) was best project award winner in 2013 from Project Management Institute (PMI). This award recognizes most successful project around the world considering best practice for project management in project lifecycle. Running behind the schedule is most common scenario in project management but ADP did exceptionally well and deliver full project 19 days before the scheduled time, including a full resolution of all issues between all parties prior to project handover. In our paper we have listed some of the facts that made this ADP project to be one of the most successful project. We have listed few lesson learned from this project which includes procurement and risk management, time management, human resource

Osmosis plays a key role in nutrient absorption (Fig 7). After your digestive system has broken down food using mechanical and chemical processes, your body is left with the key nutrients it needs to survive. Osmosis allows your body to absorb these nutrients into the intestines and individual cells. The process of active transport through the blood then distributes the nutrients to the locations where they are needed (Education.seattlepi.com,

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in

If the solution contains only sucrose then the osmotic pressure will increase substantially. This would represent a hypotonic solution because more water molecules are entering the cell meaning the solution contains no invertase. If the osmotic pressure has a slight increase than the solution contains sucrose and invertase due to the rate of the sucrose being broken down, however the cell will overtime begin to shrink. If the osmotic pressure remains close to the same than the solution contains no sucrose, containing only water and invertase. We predicted that because the height of the fluid in the osmometer tubing was increasing only a little bit our blue solution was hypertonic and contained invertase and sucrose. The invertase was able to break down sucrose into glucose and fructose which were small enough to be able to leave the cell membrane. This would reflect a hypertonic solution. We predicted this would cause the cell to shrink in size and the height of the fluid would never increase.

Clean water supply is essential in establishing and maintaining a healthy community. There are two sources of water supply which are the surface water and ground water. Most natural waters are not suitable for consumption as it is contaminated by pathogens and also natural chemicals and minerals. In addition, as a city grew, wastes from human activities contaminate most of the water supplies. Water treatment plays an important role to properly treat a contaminated source of water supply in order to protect the health of consumers. Water treatment process is defined as a process of eliminating pollutants from untreated water to produce a biologically and chemically risk-free water, which is both potable and palatable for human consumption
