In this laboratory experiment is stating that organic lipids have the ability to dissolve lipids membranes‚ and in this exercise acetone would be the main source to be used to have the reaction of dissolving the lipids inside the tubes. This exercise was to be able to observe how the chemicals reacted in rare temperatures such in heat and in cold weather‚ also this type of changes can create a new color either making the color lighter or darker. The reaction of a light color would be that it did

and significance of economics in our daily lives. The Internet was mostly used as assistance in completing this essay. Also‚ the information here are gathered and reviewed from various Internet web pages and textbooks which can be found in the list of references at the end of this assignment. To begin with‚ I shall start with the definition of economics. There is no exact definition of economics as it varies from the opinions among economist. However‚ many have chosen to agree with Alfred Marshall

Explain. Every cell contains organelles‚ the structures that carry out their specific functions. Organelles are also known as cell compartments. Eukaryotic cells have membrane bound compartments in which specific metabolic activities takes place. The organelles of the prokaryotes are not membrane bound and are simpler structures. Just like organs‚ each organelle contributes in its own way to help the cell function well as a whole. The organelles are endoplasmic reticulum‚ golgi apparatus‚ mitochondrian

Do you think that the union of the church and the state is important in our country? Why or why not? Are you in favor of it? No.Those two were in different perspective.This stipulation‚ way back Spanish Colony‚ where church and state is united as one resulted to abusive deeds of the friars. Meanwhile‚ putting down Filipinos in depression and prohibiting them be the figure heads and bodies of the Philippine Politics. So I think‚ this two is much better be separated like in our present Constitution

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 because

Phospholipids layer- 2 layers ‚ polar and non polar ‚ polar facing the extracellular fluid and cytoplasm 2. Transmembrane proteins-integral membrane proteins are proteins that expand the membrane 3. Interior protein network-peripheral proteins are in the interior side of the membrane 4. Cell surface markers are glycolipids‚ carbohydrates/lipid

The Cell membrane surrounds all living cells and is the most important organelle‚ there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the “Fluid Mosaic Model”; this is because of the way it is structured It is composed of phospholipids‚ proteins‚ and carbohydrates‚ which are arranged in a fluid
