There are many kind of cell membrane disease‚ There are : Cystic Fibrosis Cystic Fibrosis is a disease that cause by gene mutation of CFTR Protein. CFTR it’s stand for Cystic fibrosis transmembrane conductance regulator. This disease causes too much production of thick mucus‚ then the mucus will blocked the ion transport in epithelial cells that line the passageways of the lungs‚ pancreas‚ and other organs. If the passageways of the lungs is blocked by the thick mucus‚ it will make the sufferer

Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

Luigi Pirandello: 6 Characters S.C.H.P We started by using a workshop ‘The court room’. This involved Pirandello been taken to ‘Theatre Court’ over several complaints over the style in which his new play has taken. Pirandello’s personal life is key such as; his wife’s mental illness which may have drove him into obsession of the human mind‚ and how to take the human mind out of its comfort zone. This is truly developed in the opening of his play‚ by creating a naked stage with no scenery‚ the

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

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no
