Osmosis

desalination tried over the years. First, there is the process of reverse osmosis, which attempts to use a membrane to separate the salt from the water (Strauss, 2013). While membrane distillation can offer purified water, it is often a difficult process to master. Another process that has been used in recent years is nano-osmosis, which allows for less energy use but requires the use of small, almost microscopic technology. Nano-osmosis filters the salt out of the water with tiny tubes of…

The first and second tests for the presence of ammonia and Chloride did not show any measurable results in any of the samples. The third test, the 4 in 1 test showed the Fiji bottled water to have hard water as compared to the Dasani and tap water. Fiji water had the highest chlorine content, double that of tap water. Tap water and Dasani water had higher alkaline than the Fiji water. The tap water rated highest on the phosphate content test followed by Dasani with half as much phosphates…

F214 Communication, Homeostasis and Energy Module 2 Excretion 4.2.1 Excretion a. Define the term excretion Excretion-The removal of metabolic waste from the body which are by products or unwanted substances from cell processes. b. Explain the importance of removing metabolic wastes, including carbon dioxide and nitrogenous waste from the body Carbon dioxide Excess carbon dioxide is toxic and has three main effects: The majority of carbon dioxide is carried in the blood as…

Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating…

adopted in the pharmaceutical and semi-conductor industries. Sodium metabisulfite or sodium bisulfate exists as a powder or solution and is mixed on site. However, the solution itself becomes an incubator of bacteria, causing biofouling of the reverse osmosis membranes. Additionally, the two compounds are hazardous to handle, maintenance of the equipment used is expensive and sodium sulphate may be formed, which in turn can act as a stimulant to sulphate reducing bacteria(Bagchi…

Evaluating overall results compiled by practical investigations, the water sample showed very positive results with very minimal flaws in its purity. Observing the physical properties of the sample it had no turbidity and looked relevantly clear. Data shown here may be inaccurate due to many varied factors in the lab testing. Most of the testing heavily relied on the judgment of the human eye to compare charts colours possibly resulting in human error. A low 5 m/L’s was tested each time when…

Textbook Reference: 6.4 What Are the Active Processes of Membrane Transport? Page: 120 5. Barrier formation is only one function of the cell membrane. Describe some other functions of the membrane and discuss how the membrane is suited for those functions. Answer: Membranes function in processing energy transformation and in the organization of chemical reactions. Integral and peripheral proteins contribute to these functions. The membrane serves as a holding site for the catalytic enzymes…

there are more solutes surrounding the cell rather than in it. Osmosis occurs as a result of this because water diffuses down the water potential gradient to achieve equilibrium. This causes the onion root to lose water because the water from the onion root cells move from an area of high water potential, out of the cell, to the solution that contains a higher concentration of sucrose. The observations above also show that as osmosis occurs, the onion cells begin to shrink and shrivel; this…

Freezing point is the temperature for a particular compound where the liquid freezes to form a solid (Chemistry Dictionary). If salt is added to water, it freezes at lower temperatures. If there are fewer water molecules, then freezing occurs at a slower rate (Salt and the Freezing Point of Water). Pure water freezes at 0º Celsius, but water that is combined with salt will freeze at a temperature less than 0º Celsius (Oleson, Andrew and Daly, Terik). A solvent is something in which other things…
