Organ Donation Brain Dead
568 wordsThe debate regarding the ethical issues about organ donation and transplantation has been present for many years. This is primarily due to the unique exchange that must occur. No other treatment so intimately involves the public. People must donate their organs or tissues to make the treatment possible. The question that remains is why are people not donating their organs? One of the main reasons people do not donate organs is distrust of the medical profession. People are afraid that physicians...

Petri Dishes Bacteria Cells
1,566 wordsIn this lab we observed the growth of bacteria in a conjugation and transformation experiment. We expected the mating plate of the conjunction to grow and the bacteria on the transformation plates to grow also. We also practiced using aseptic techniques to clean the lab benches and to keep the bacteria from being contaminated from outside bacteria. This lab will take a total of 2 days because of the observations that need to be made. The parts of this paper will explain the procedure and the obs...

Volcanic Eruptions Directly Related
322 words2. There are three main factors that determine the nature of volcanic eruptions. Each factor has defined characteristics that can determine the effects of the volcano. The factors are the magmas composition, temperature and the amount of dissolved gases. Each of these affects the magmas viscosity, which is directly related to the nature of the eruption. The amount of silica content is directly related to the viscosity, as well. The composition of Mafic magma is about 50 % silica, which makes it ...

Parts Per Million Shortness Of Breath
1,183 wordsSmog has been around for a pretty long time, people just knew it as something else. Smog comes from the word smoke and fog, and that's practically what it is. It was a serious problem before, before nature and humans went unharmed in the presence of smog but now it's serious. What does all of this polluted air do to the body? The answer depends on the situation. How long a person is exposed to pollution, the type and concentration, the place, time and day, temperature, weather and more. But one ...

Cross Sectional R R
864 wordsDetermination of r for a Metallic Conductor To determine the resistivity (r) of a given sample of wire Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R = Voltage / Current Resistance of a co...

Nitrous Oxide Neuromuscular Junction
1,553 wordsAnesthesia is a partial or complete loss of sensation or feeling induced by the admin- is tration of various substances. For many decade, people have used one form of an anesthetic during surgical procedures. Some people also use some of these anesthetics as recreational drugs, e. g. laughing gas (a. k. a. Nitrous Oxide). The term anesthetic literally means "without feeling." There are many different types of anesthesia, but they are usually put into three groups. These groups are gene- ral anes...

Life On Mars Washington D C
1,018 wordsIf life ever evolved on any of the other planets, Mars is the likeliest candidate. After Earth, Mars is the planet with the most hospitable climate in the solar system. So hospitable that it may once have inhabited primitive, bacteria-like life. Outflow channels and other geologic features provide extensive evidence that billions of years ago liquid water flowed on the surface of Mars. Continuing changes is an accomplishment in modern American technology and it gives the world a step forward in ...

Chicken Came First Laying An Egg System
438 wordsAccording to principles of Thermodynamics, the system tries to go to the state of minimum energy. Of course, we would have to assume that: 1. the system is not tight (so that energy may escape to some other system). The principle of conservation of energy has to be followed. 2. the system is not in equilibrium and is trying to achieve it. 3. Initially, only one thing exists at one time, either the egg or the chicken. In such a case scenario, the chicken has to come first. When an egg is first pr...

Recurring Theme Feel Sympathy
1,704 wordsDespite the mask we wear to seek refuge and to hide our suffering from the outside world, we as a society go to our own inner selves in determining the true value of personal suffering. Not for redemption, but for the feeling to be pitied for is why humans often dwell in emotional pain for a longer time than necessary. Dostoyevsky proves this theory to an extraordinary extent in Crime and Punishment. Dostoyevsky finds a way to drill deep into the human psyche and finds the solution to each indiv...

Blood Vessels Social Behavior
1,527 wordsInsect, small, air-breathing animal characterized by a segmented body with three main parts head, thorax, and abdomen. In their adult forms, insects typically have three pairs of legs, one pair of antennae, and in most instances, two pairs of wings. Insects rank among the most successful animals on Earth. About one million species of insects have been identified so far, which is about half of all the animals known to science. That is why for every pound of human on the earth there are 10 pounds ...

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 ...

Cold Blooded Oxygenated Blood
1,437 wordsMammals have existed for the past 200 million years. According to fossil evidence, they evolved from a mammal like reptile group. These reptile ancestors were small, active carnivores. They were equipped with several specialized types of teeth. Their limbs were positioned more directly under the trunk as opposed to spreading out to the sides. Both of these characteristics are prominent features of mammals. For the past 70 million years mammals have been the dominant animals in terrestrial ecosys...
