The mitochondria has an eggshape structure. The mitochondria consists of an inner and outer membrane. The outer membrane is what shapes the organelle to its egglike shape. The inner membrane which folds inward makes a set of "shelves" or cristae that allow the reactions of the mitochondria to take place. The more the mitochondria makes these reactions the more the inner membrane folds. This happens because the mitochondria now has more surface area connecting it

INTRODUCTION Theories explaining biological evolution have been bandied about since the ancient Greeks, but it was not until the Enlightment of the 18th century that widespread acceptance and development of this theory emerged. In the mid 19th century english naturalist Charles Darwin - who has been called the "father of evolution" - conceived of the most comprehensive findings about organic evolution ever1. Today many of his principles still entail modern interpretation of

Questions on the origin of life and of the universe must have challenged human curiosity and imagination as soon as early man had time for activities other than survival. In 1859, Charles Darwin published the Origin of Species, and since then, people have debated between the creationism and evolutionism theories. The theory of evolution has been supported only through various religious writings, particularly the Bible. Creationists believe in a divine creator, God. Creationism ha

We share many experiences with the kings of old: pastries, for instance, and home entertainment and vacation trips to far-off lands. Ancient-day common folk knew nothing of such things. Then again, they weren't constipated... We are. Not all of us, of course. But enough Canadians so that some doctors call our a constipated society. And even if you're not constipated, your present day diet may be leading you to more serious complaints like disorders of the large intestine

A simulated flight environment for pilot training may soon be made more realistic through the use of eye-tracking technology developed by researchers at the University of Toronto's Institute of Biomedical Engineering (IMBE). Many safety and cost benefits are obtained by training aircraft pilots under simulated conditions, but to be effective the simulation must be convicingly realistic. At present, th e training facili

If you know where and when to look, you can treat yourself to a colourful display of atmospheric haloes, spots and pillars. These images can tell you something about the clouds overhead and possible changes in the weather. All of these images are created by light shining through cirrostratus clouds. These clouds occur at an altitude of 6,000-12,000 metres. They appear as a thin sheet or layer (strata) that is pure white. The layer of cloud is so thin (only 100-450 metres) that

"Fractal Geometry is not just a chapter of mathematics, but one that helps everyman to see the same old world differently". - Benoit Mandelbrot The world of mathematics usually tends to be thought of as abstract. Complex and imaginary numbers, real numbers, logarithms, functions, some tangible and others imperceivable. But these abstract numbers, simply symbols that conjure an image, a quantity, in our mind, and complex equations, take on a new meaning with f

The name Fritz Haber has long been associated with the well-known process of synthesizing ammonia from its elements. While primarily known for developing a process which ultimately relieved the world of dependence on Chilean ammonia, this twentieth century Nobel prize winner was also involved in the varying fortunes of Germany in World War I and in the rise to power of the Nazi regime. Haber was born on December 9, 1868 in Prussia. He was the son of a prosperous German chemical me

Science is a creature that continues to evolve at a much higher rate than the beings thatgave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the timefrom analytical engine, to calculator, to computer. But science, in the past, has always remaineddistant. It has allowed for advances in production, transportation, and even entertainment, butnever in history will science be able to so deeply affect our lives as genetic engineering willundoubtedly do. Wit

Webster's dictionary defines a Geostationary orbit as of, relating to, or being a satellite that travels above Earth's equator from west to east at an altitude of approximately 35,900 kilometers (22,300 miles) and at a speed matching that of Earth's rotation, thus remaining stationary in relation to Earth. 2. Of, relating to, or being the orbit of such a satellite. In plain English, a satellite matches the earth's rotation making it seemingly hover over one spot
