Essay about Effect of Concentration on Osmosis

6. If an object is 4.5 cm long, what would its length be in mm?

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 following experiment was conducted to investigate the effect of concentration on a potato core. The experiment was done see whether or not the concentration in the NaCl solution would effect the mass of a piece of potato core, the experiment briefly showed that each concentration of NaCl decreased the mass of the piece of potato.

Students will label 3 test tubes hot, cold, and room temperature and place potato cub (3X3X3 cm)

Mix each one with a glass rod and always make sure to wipe the glass rod after each use.

The main purpose of the experiment was to test the idea that water would move from the higher concentration to the lower concentration. In order to test this theory, we placed potato slices in 7 different containers, each containing different concentrations of NaCl, to measure the weight change from osmosis. The containers ranged from 0M NaCl all the way to .6M NaCl. We measured the potato slices before and after placing the slices in the solutions and recorded the net change in weight to determine the tonicity of the potato cells. Our results showed that the potato slices put in a NaCl solution of .2M or higher lost weight and the potato slices put in a NaCl solution of .1M or lower gained weight. This shows that the osmolarity of the potato falls within the range of .1M to .2M, and it also proves the process of Osmosis by having the higher concentration move to the lower concentration. In addition to this, it can be concluded that the osmolarity of cells can be determined by observing the affects of osmosis.

2. Place 10 randomly selected sowbugs in each of the 3 empty tin bowls for 3 minutes to allow them to acclimate to the environment.

Cut the potatoes using a cork borer approximately 5cm in length and 1cm in diameter. Using the appropriate tool cut the potatoes into cylinder form measuring the cylinders with a ruler.

G. Sucrose Solutions of Different Molarities Percent Change in Mass after 30 minutes of Submersion in Water

1 ml of water should be added to the first test tube and make a note. In the second test tube, 1 ml of methyl alcohol should be added. In the third test tube, 1 ml of hexane must be added. Lastly, the fourth test tube will be a control.

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

Remove the skin of the potatoes as well as cut into average sized pieces. Remove the skin

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,

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)

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
