Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? ____________________________________________________________________________________ 3. Describe the results of the attempts to diffuse glucose

The Roles of the Nephron of the 120 ml of blood that is filtered by the kidneys each minute‚ only I ml (that’s less than I%) turns into urine that will eventually leave the body (after approximately 300 - 400 mis of it accumulates to fill the bladder!) That leaves 119 ml of fluid called filtrate to be returned back to the blood stream. Good thing‚ otherwise you would have to micturate (pee‚ urinate) once every 3 minutes and drink 1 L of fluid every 10 minutes in order to maintain Homeostasis!!! The

Introduction The economic benefits of using untreated and treated crop residues as feed for ruminants mainly depends on the source and cost of crop residues‚ cost of treatment‚ cost of urea or other ammonia source‚ on the price of protein supplements‚ as well as on agricultural production and technical levels and other factors. In relation to the potential of crop residue use‚ countries can be divided into four types: Type 1 are developing countries and regions with a high population density

* A reactant in an enzyme-catalyzed reaction is called a substrate. The area of the enzyme that binds to the substrate is called the active site - where the action takes place. * Cofactors and coenzymes are small molecules or ions that help enzymes to act.

Crystallization and Melting Points Organic Chemistry 221 9/19/2012 Intro/Purpose: The purpose of this lab was to use crystallization to separate a compound from a solvent and be able to choose the best solvent to do so. Then identify an unknown and verify purity using melting points. Solubility contributes to crystallization; because a solute has lower solubility at lower temperatures‚ which makes the solvent separate from the solution as a solid. This process is important to understand because
