3. Why don’t the terms depolarization and action potential mean the same thing? The terms depolarization and action potential differ because are excitable cells that communicate by transmitting electrical impulses that are capable of producing rapid electrical signals and depolarization in the interior surface of the membrane which becomes less negative and the exterior surface becomes less positive. Additionally‚ when depolarization reaches a certain threshold‚ an action potential is initiated

The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis

doctors in the 1950’s‚ cells from her tumor were sent for research without her consent; and unfortunately the credit/rights that her and her family deserves have been thrown in the air. Medical procedures of the 1950s and 60s caused people to question if what was being done was moral or ethical for the family. Upon observation of the arguments made by the people and the scientific community‚ it is simple to see the fine line that people’s views may be approaching. HeLa (cells of Henrietta Lacks) have

and curious neighbours looked on. The car arrived at the station‚ the suspect was brought inside‚ formally booked‚ again warned of his Miranda rights‚ finger printed‚ and a complete identification was made. The suspect was then taken to a holding cell where he was left blindfolded to ponder his fate and wonder what he had done to get himself into this mess. Consider the police procedures which make arrestees feel confused‚ fearful‚ and dehumanized. Note that this policeman is wearing sunglasses

TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage of materials across their

Stem cells agreement by Zayne Burnham Many scientists are now researching special types of cells called stem cells. Stem cells are very important and have the potential to cure many diseases; however there are also many issues to consider when using stem cells. Stem cells research has created concern for some in the community‚ national and international.beacause the best source of stem cells is growing human embryo. The dilemma is that the growing embryo is the earliest stage of human life extracting

The fluid mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic
