.... thickor needle like so it can reduce water loss through evaporation. The chamise, for example, has small, needle-like leaves that store up and save the moisture in the plant. The is the home of many species of reptiles, birds, and mammals. There are animals such as the alligator lizard, western rattlesnake, quail, roadrunner, scrub jay, brush rabbit, coyote, and mule deer. Some species are restricted to habitats only, but others inhabit adjacent vegetation types as well. The environment is very harsh. Annual rainfall ranges from 12 to 24 inches, with 85 percent falling between November and April. Summers are dry and hot, .....

.... light which is seen in the sky. Rainbows can be seen in moonlight or in artificial light. They are caused by the sun shining through tiny drops of water in the air. A rainbow's brightness depends on how large the drops are. The larger the drops are the brighter the rainbow will be. Many people think that a rainbow is only made of six colors, but it is really make of seven. The colors in order are red, orange, yellow, green, blue, indigo, and violet. A primary rainbow is a rainbow with red on the outside and violet on the inside. The largest rainbow visible to observers on land is a semicircle, but many times you can only .....

.... of measuring the presence of a given substance. Both methods turn around a compounds polarity. As one recalls, polarity is a measure of the electronegativity of a compound determined by their placement in the periodic chart. Specifically, in this lab we are talking about the difference in polarity between the atoms of oxygen and carbon. Ferrocene is relatively low to none in polarity. Acetylferrocene, because of the carbonyl functional group, is more polar than the ferrocene. Moreover, diacetylferrocene, because of the 2:1 ratio of the carbonyl groups over the acetylferrocene, is the most polar of the lot. As stated above, b .....

.... procedures used in human embryo cloning have been around for many years, and have been used in the cloning of cattle and sheep embryos, for the production of animals with known genetic traits. The news of human embryo cloning did not surprise many people in the scientific community, but it shocked the general public.”(psu.edu) Many biologists believe that they have a personal duty to the improvement of society, perhaps even a moral obligation. To this end the techniques of embryonic cloning and alteration have been offered to society as an option for the improvement of humanity. Doctors hope that by being able to study .....

.... west to Ethiopia and Somalia in the east. These nations are among the world's poorest. The area is one of social and biophysical crisis because of the way the population are forced to live; they are destroying the productivity of the land. The alarming rate of population growth and ever increasing pressure on the land have initiated an expansion of desert-like conditions into the Sahel - a process called desertification. Traditionally, the people of the drier, northern Sahel followed a nomadic lifestyle, constantly moving their herds of cattle, sheep and goats over large areas in the search for suitable grazing land. These mo .....

.... trees can store much, much more carbon dioxide than a new tree could. By cutting and burning these magnificent seasoned trees, the CO2 is being released back into the atmosphere. These releases of carbon dioxide add up in our surroundings, only to intensify Global Warming. Although this shows what happens when one burns and cuts down old forests, one must still plant new trees for long term plans, not letting them grow for a few years, to then cut them down. There are many methods for planning a forest. The simplest method of replanting a forest is to leave it to nature. A suitable seed bed in which trees will readily take .....

.... spores could be contaminated or wet wood, bird droppings in air ducts, or decaying fireproofing materials. The fungus causes pneumonia in a host with a weak or otherwise compromised immune system. Patients at risk are those undergoing organ transplant or bone marrow transplants, and depending on the type of transplant, mortality rates are as high as 95%. Bone marrow transplant patients, the highest risk group, should be treated like they are immunosuppressed for up to four weeks after the procedure. The portal of entry is through the upper respiratory track. The infection then becomes systemic and is spread into multiple de .....

.... melanogaster. During this experiment, monohybrid and dihybrid crosses were conducted with Drosophila melanogaster. Our objective was to examine the inheritance from one generation to the next. We collected the data from the crosses and analyzed them in relation to the expected results. MATERIALS AND METHODS For the monohybrid cross in this experiment, we used an F1 generation, which resulted from the mating of a male homozygous wild-type eyed fly with a female homozygous sepia eyed fly. Males and females are distinguished by differences in body shape and size. Males have a darker and rounder abdomen in comparison to fema .....

.... basic explanation of this we will assume a linear plane, one in which all forces act in only one direction. Therefore when the apple fell it went straight towards the center of the earth (accelerating at about 9.8 meters per second second). Newton then figured that the same force that pulled the apple to Earth also pulls the moon to the earth. But what force keeps the moon from flying into the earth or the earth flying into the sun (Edwards 493)? To better understand this, one other aspect must first be understood. Galileo showed that all objects fall to the earth at the same rate (the classic cannonball and feather proved t .....

.... was chosen to see which clothing insulator retains the most heat. "Insulation is material that protects against heat, cold, electricity, or sound." (Science Encyclopedia, 1984). In this case the insulation will be protecting against a cold temperature. The hypothesis is if denim, cotton T-shirt material, wool fabric, polyester fabric, thermal underwear, and a Ziplock bag with out insulating material are tested to see which one retains the most heat, then wool fabric will retain the most heat because it holds an important place in today's textile trade because of its good insulation and the fact that it comes from the .....
