Membrane Functions: Aim: To demonstrate the process of osmosis using a chicken’s egg Hypothesis: I predict that the egg’s mass after 10 min. in the 5% salt solution would increase due to and balancing out the solution. In the 10% salt solution‚ the egg’s mass would decrease since there is a high amount of salt. In the dilute water solution‚ the egg’s mass will increase‚ as the membrane would take in that water. Materials: 1- One fresh egg 2- One plastic spoon 3- One plastic fork

reduction of ephedrine using red phosphorus and iodine. Synthesis is relatively simple‚ but entails risk with flammable and corrosive chemicals‚ particularly the solvents used in extraction and purification; therefore‚ illicit production is often discovered by fires and explosions caused by the improper handling of volatile or flammable solvents. Most of the necessary chemicals are readily available in household products or over-the-counter cold or allergy medicines. When illicitly produced‚ methamphetamine

Although it may be hard to change society’s long standing opinion that mass-production by any means necessary is the right way to go‚ organic farmers are now making a larger appearance on the world stage. Organic farming can be the solution‚ and it is possible to feed a booming population through this type of farming if three simple things are

molecules can diffuse across cell membranes while some substances must be transported across the membrane by proteins. The membrane is in control of what enters and leaves the cell. However‚ certain conditions may damage the cell membrane’s structure. Beet cells‚ which are plant cells‚ have a water-soluble pigment called betacyanin‚ which is stored in its vacuole. The tonoplast‚ or the vacuole’s membrane‚ acts with the cell membrane of the cell to prevent the
