ETHANOL (E85): Types of fuels are ethanol‚ natural gas‚ diesel and hydrogen. Ethanol is simply grain alcohol obtained from corn. The corn is ground to powder form and mixed into a mash that is distilled to obtain ethanol which is a flammable liquid and then used as fuel. The ethanol could be mixed with gasoline blend in order to obtain reduced cost. In addition‚ the emission of Co2 would be reduced‚ but not completely eradicated because of its content of 90 percent gasoline and 10 percent ethanol

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

a.1 Eukaryotic Cell vs Prokaryotic Cell All cells can be classfied into prokaryotes and eukaryotes. Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.

On the discipline grid it says disrespectful behavior in the 5th offense is 5 OSS days. On the discipline grid disruption of class in the 5th offense is 3 OSS days. We have been asked plenty of times in Mrs. Kayla Ingalls class to stop being disrespectful and disruptive‚ and we have not listened to her. We are walking all over her because she is new‚ plus‚ she is a fun and exciting teacher‚ but since she is new‚ we aren’t treating her the way we should treat her. She has wrote us detentions but has

Essay topic: “ Disruption in the natural order in the play Macbeth leads to chaos” Macbeth by William Shakespeare is set in a society where the idea of loyalty to the superior is absolute. William Shakespeare portrayed that there was a danger in disturbing ‘the great chain of being’ which ranked all creations including human society. It ranked humans above animals‚ nobles above the poor and at the top of the hierarchy was the king. When Macbeth murders King Duncan the chain was violated resulting

Biology Lab T 10:50 The Effects of Alcohol on the Cell Membrane Introduction To understand the effects of alcohol on cell membranes can help one understand more about the effects of alcohol on human cells that are contained in the digestive system and the blood stream. It is important to study this effect due to the fact that it can lead to the understanding of the dangers of alcohol‚ over consumption‚ and even possibly alcohol poisoning. Performing this lab enables the students to have a firsthand

Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

½Give an account of the structure and properties of Biological membranes. Include details of the modifications of membrane structure found in different specialised cells and organelles½ The Fluid Mosaic model was codified by Singer and Nicolson in 1972. It describes the structure and properties of the cell membrane very simply. Every membrane consists of a Phospholipid bilayer. This is simply two layers of phospholipid molecules that come together due to their unique properties. The heads of the
