Experimental Protein

... extracted for the electrophoresis. Dilution was prepared of this concentrated extract; positive correlation made between the concentration of BSA and measured absorbance. This correlation helped to draft a regression line, which was useful in finding concentration of protein extract. An electrotransfer on PVDF membrane was done after the gel electrophoresis. These migrations of proteins based on their molecular weight of three solutions. Using the polyacrilamide electrophoresis, proteins were separated based on their molecular weight. ...

Bio-report

... freely in and out of the cell to maintain the balance. b.Active Transport In active transport a cell moves materials from an area of low concentration to an area of high concentration, this process is the opposite of osmosis or diffusion. Active transport requires energy because it is moving against the concentration gradient. In active transport the cell uses ATP to remove unwanted materials and to receive needed ones. For example a muscle cell wants potassium and wants to get rid of a sodium, the cell releases ATP to the pump proteins w ...

Into The Depths Of A Black Hole

... and processes involved with the space phenomenon of the black hole. It will describe how a black hole is generally formed, how it functions, and the effects it has on the universe. In order to understand what exactly a black hole is, we must first take a look at the basis for the cause of a black hole. All black holes are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all ...

Becoming An Ecologist Is An Exciting Venture

... prime responsibility of an ecologist. Ecologists mainly study the ways in which mankind is destroying the natural ecosystems of the earth and how people can help to revive them. Louise Miller once said that,". . . the ecologist is the one that brings together the study of all natural systems- earth, air, water, plants, and animals. Connections between living organisms and effects of their interactions are ecologists' concerns. . . . .The balance of nature, wherever it occurs, is what you will investigate and analyze"(17). Since a career ...

Killer Bees

... South America, extending their range by as much as 500 km (300 mi) per year. By the 1980s, Africanized honeybees had reached Central America and soon colonized Mexico. In 1990, the first swarm was found in the United States. The bees spread from Texas to New Mexico and Arizona and then into California by 1994. The bees reached an apparent climatic limit to their southern range in the middle of Argentina, and their range is expected to be similarly limited to the southern and coastal states in the United States. They have hybridized to s ...

Copper And Molybdenum Deposits In The United States

... high to fulfill the needs of foreign demand. Copper was first used by people around 4000 B.C. in the manufacture of tools because of its malleability and later became an important additive in harder, more useful metals such as bronze (copper+tin; 2500 B.C.) and brass (copper+zinc; 0 A.D.). The growth of copper production in the United States has been a relatively recent occurrence. North American French explorers knew of sources of native copper in the region of Lake Superior and the area natives had copper jewelry and ornamentation. Ear ...

Autism 3

... I was later told the boy {my brother} was autistic,” says Tamara Robinson in an interview. Autism is “a syndrome of childhood characterized by a lack of social relationship, a lack of communication abilities, persistent compulsive, rituals, and resistance to change” (Paluszny 1). For centuries, medical professionals have tried to understand autism and its origin. The above example shows only a few examples of autistic behavior. The history of autism extends, as far back as the late sixteenth century; however, during that time it wa ...

Global Warming 2

... about how the earth's climate responds to these gases, global temperatures are rising. Energy from the sun makes the earth's weather and climate, and heats the earth; in return. Greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the energy that leaves, botteling heat like the glass panels of a greenhouse. Without this natural "greenhouse effect," temperatures would be alot lower than they are now, and life like today would not work. Instead, thanks to greenhouse gases, the earth's average temperature is bet ...

Acid Rain: Cause And Effects And Issues

... Among the many plants in Ontario where sulfuric acid is produced, there are three major plant locations that should be noted on account of their greater size. These are: (1) Inco. - Sudbury, (2) Noranda Mines Ltd. - Welland, and (3) Sulfide - Ontario There are a number of factors which govern the location of each manufacturing plant. Some of these factors that have to be considered when deciding the location of a Sulfuric Acid plant are: a. Whether there is ready access to raw materials; b. Whether the location is close to ...

... look good ( MS Bookshelf). There are many procedures that need to be followed in order to get an application for silicone inflatable breasts (MS Encarta). There are various test, experimentation, and evaluations that need to be done ("Student Handbook"). The most important ones are the; Chemical Characterization, Pharmacokinetic Studies. These are all tests that the Plastic Surgery and Reconstructive Surgery Devices Branch Division of General Restorative Devices and the Office Of Device Evaluation all require (ODE documents 6). The Chemic ...

Endangered Species

... of animals, but now the changes are greatly accelerated by humans activity. Clearing land for farms and towns, lumbering, mining, building dams, and draining wetlands all alter the environments so extensively that ecosystems may be completely destroyed. With a burgeoning human population requiring food, shelter, and clothing and constantly demanding more energy-using devices, the temperation to exploit land for human use without regard for consequences is great. Frequently, several forms of environmental change are responsible for the disap ...

Black Holes 2

... and are overwhelmed by their own gravity. When this happens they cannot keep from collapsing. After stars collapse, they start rotating and as they are spinning, their gravity becomes stronger causing them to shrink. As the object becomes smaller, it starts spinning faster and faster. Then the core compacts into a mathematical point with virtually zero volume, where it is said to have infinite density. This is referred to as a singularity. When this happens, escape would require a velocity greater than the speed of light. No object can rea ...
