by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate

As a check on your assumptions‚ be sure that the elements in series have the same current and that the elements in parallel have the same voltage. Restrict your decisions to single elements‚ not combinations of elements. (a)R1‚ R2‚ and E are in series; R3‚ R4‚ and R5 are parallel. (b)E and R1 are in series; R2‚ R3‚ and R4 are parallel. (c)E and R1 are in series;

Your last paragraph was very detailed with great information about the cell membrane‚ you stated “ The cell membrane is very thin and fragile‚ and it contains two different types of proteins. “Integral proteins are part of the membrane structure and cannot be removed without damaging or destroying the membrane. Peripheral proteins are bound to the inner or outer surface of the membrane and are

On the Kelvin scale‚ 0 degrees is absolute zero‚ the coldest possible temperature. Absolute zero is equal to -273.15 °C or -459.67 °F) A. How does the change in temperature affect the speed of the molecules? __If the temperature is colder the molecules move slower and if the temperature is hotter the molecules move faster.

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction

"Integrity without knowledge is weak and useless‚ and knowledge without integrity is dangerous and dreadful"‚ quoted Samuel Johnson. Integrity in the eyes of a teenager means not cheating in class‚ obeying and respecting school rules‚ and finishing and completing anything assigned in school. When in class‚ teenagers have plenty of opportunities to cheat during tests‚ quizzes and other assignments. Integrity means not taking advantage of these opportunities and being honest towards yourself and

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate
