.... make. This species is the only species that breeds anywhere in Africa. It breeds on some twenty islands, from Hollams Bird Island off the coast of Namibia to Bird Island in Algoa Bay. At one time the population of the African Penguin was quite large but some man caused factors has drastically reduced their species. A long time ago the early European settlers at the Cape of Good Hope realized that penguin eggs were good for eating and over the years millions of penguin eggs have been collected greatly reducing the population of the African penguin species, and even to make things worse they started the practice of destroying any i .....

.... and easily. There skin is rubbery and smooth. They have a layer of fat beneath there skin which keeps the dolphin warm and stores food. It is also think that the blubber helps them to stay afloat, since it as lighter then water. have distant cautious that make them direct the other whales, most dolphin species have a distinct beck where as porpoises have a more rounded shape to there head. They also have a hooked-shaped dorsal fin not fend in other specious, as will as conical teeth. Erans explains that evolved from the Mesonychicsi, large land mammals and the earliest recognizable cetaceans lived about 50 million year ago. The earli .....

.... then to have an arrested development. This ethnic insult came under fire in the 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became called "Down's syndrome." In the 1970s, an American revision of scientific terms changed it simply to "," while it still is called "Down's" in Europe. There are three main types of . The vast majority of children with (approximately 95 percent) have an extra 21 chromosome. Instead of the normal number of 46 chromosomes in each cell, the individual with has 47 chromosomes. This condition is called trisomy 21. The second type is called transloca .....

.... of a cell. Like wise, the surface area and volume of a cell are directly influential in the efficiency of the cell’s nutrient absorption and waste expulsion processes. Since the cell membrane of an eukaryotic cell is its only source of nutrition, its surface area must be large enough to allow the cell’s organelles to receive the material it needs or it will die. The eukaryotic cell does this by maximizing the surface area to volume ratio. By using the surface area and volume equations for a sphere you can estimate the surface area of a small cell. By modeling the growth rate of the surface area and volume of a sphere on a linear graph it .....

.... The subunit of the ribosome recognizes the G-cap and then finds the initiation codon to start translation. As the mRNA comes finishes transcription, the Poly A tail is added to the 3¹ end. As the two ends are placed the mRNA becomes pre-mRNA. The pre-mRNA consists of splicing and non-coding regions. pre-mRNA molecules are much longer than the mRNA molecule needed to code for its protein. The regions that do not code for amino acids; aa, are scattered all along the coding region. The genes are split with coding regions, called exons, short for expressed regions; in between the exons the non-coding region called introns exist. .....

.... evolved in what is now the Indian Subcontinent. From their placement in India, then still lowland, primates spread throughout the world once more. Some returned to North America, only to be wiped out by rodents already living there. Others spread to Europe and the Middle East. By this time, Africa had just split from marsupial overrun Gondwanaland. About a million years later it reached the Middle East, and primates moved in. By now the world had cooled enough that the primates in Europe had been decimated to near extinction. They also migrated south, for the Mediterranean Sea was at that time dry lowland. Now almost all of the .....

.... 21. Trisomy 21, the inheritance of an entire third copy of this chromosome, accounts for 95 percent of Down syndrome cases. Two other abnormalities each account for 2 to 3 percent of all cases. The first, translocation, takes place when a child inherits an extra piece of chromosome 21 attached to a different chromosome. The second, called mosaic Down syndrome, results when only some cells in the body have the extra chromosome. There is no cure for Down syndrome although prenatal tests are available to identify fetuses with the disorder. Down syndrome can be diagnosed just by looking at the baby at birth. The facial features and chara .....

.... and hydrochloric acid, most of the organic acids, most chlorine gas, and chloride solutions. When natural, is reported to become very radioactive after being bombarded with neutrons. The emitted radiations are mostly positrons and gamma rays. The hexagonal alpha form changes to the cubic beta form very slowly at around 880 degrees Celsius. The metal combines with oxygen at red heat, and with chorine at 550 degrees Celsius. when a metal, is considered to be physiologically inert. Pure dioxide is kind of clear and has an extremely high index of refraction with an optical dispersion higher then diamond. The location of on the Periodic Cha .....

.... about thirty-six hours to dig itself out of the nest. When it is born it is the about the size of a child's hand. It eats the Portuguese Man of War, a very deadly jellyfish. It has very tough skin so it does not have to worry about getting stung by the jellyfish. It lives in the ocean all of its life and lays its eggs on the shore, when the babies are born they go on their own to their own life. The turtle lives in a type of weed which floats in the ocean drifting with the currents, the environment is very bad for the turtle since there is a lot of offshore dumping by ships, polluting the ocean. There is a total of thirteen tons of trash b .....

.... United States and it's people. When ever plutonium was mentioned the first thing that came to people's minds were the bombings of Hiroshima or Nagasaki. No one ever considered the fact that plutonium could be used for more constructive purposes such as: sources of energy or to keep a person's heart beating. We did begin to produce more plutonium but the majority of the substance was used towards our nuclear weapons programs. Along with reactors, sometimes comes a meltdown which can cause harmful effects if it isn't controlled quickly enough. After such instances as the Hanford, Washington reactor meltdown and the accident in the U.S .....
