Ancient Egyptian Beliefs In The Afterlife
1,487 words... to compare to the great houses in which the Pharaoh or other important persons had lived (Badawy 47). The burial chambers of the mastaba, along with those of virtually all other forms of Egyptian architecture, housed paintings and relief sculptures depicting the actions of everyday life. The nether life destiny is often associated with this "everyday life", where the spirit experiences all the aspects of their mortal life on earth. Often, mastaba's were arranged in cemeteries forming a grid ...

Neuro Transmission Positive Charge
488 wordsneurotransmitters play a central and critical role in our psychological existence, identity, and experience of the world Neurotransmitters are chemicals that communicate between nerves. In some ways, neurons are like computers: they receive messages, process those messages, and send out the results as new messages to other cells. In the case of neurons, messages consist of chemicals that interact with the outer surface of the cell membrane. This chemical interaction with the cell membrane causes...

Plasma Membrane Permeable Membrane
777 wordsThe plasma membrane is the boundary of life; this selectively permeable membrane allows the cell to maintain a unique internal environment and to control the movement of materials into and out of the cell. The phospholipid bilayer (fluid music model) with specific membrane proteins accounts for he selective permeability of the membrane and passive and active transport mechanisms. Membrane phospholipids are amphipathic. Cell membranes are phospholipid bilayers with the hydrophobic hydrocarbon tai...

Cystic Fibrosis Endoplasmic Reticulum
717 wordsCystic Fibrosis Commonly found in young children, Cystic Fibrosis is an inherited disease that is caused by a genetic disorder. The disease originates in the production of a critical protein that transports chloride ions from one place to another called a cystic fibrosis transmembrane conductance regulator (CFTR). The DNA of an infected person is missing three building blocks called nucleotides causing the CFTR protein to be missing one amino acid called phenylalanine. Normally, a healthy CFTR p...

This disease is the most common genetic disorder amongst Caucasians. Cystic fibrosis affects about one in 2, 500 people, with one in twenty five being a heterozygote. With the use of antibiotics, the life span of a person afflicted with CF can be extended up to thirty years however, most die before the age of thirteen. 1 Sinc...

Hydrogen Bomb Nuclear Fusion
2,740 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...

Inversely Proportional Cross Sectional
1,082 wordsAim I am going to be studying the resistance of wire. The purpose of this investigation is to see how length and thickness of wire affect the dependent variable, resistance. Prediction I predict that, as the length of the wire doubles, the resistance will also double, but as the cross-sectional area of the wire doubles, the resistance halves. This means that the length will affect the resistance more than the thickness will. Hypothesis Resistance is caused by electrons bumping into ions. If the ...
