dissipating " and the cause is laid primarily to man - made chemicals
( Bowermaster et al, 1990, p.27 ). If enough of these man - made
chemicals are released, " the ozone layer would be weakened to such an extent
that it does not filter out the sun's invisible and dangerous ultraviolet rays "
( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the
environment. Ozone depletion has been described as " potential

.... the bases are abbreviated as A, C, G, and T (respectively) for simplicity reasons. At the smallest level, DNA is organized into a double helix. The DNA helix is then repeatedly coiled to allow more of it to fit into a compact space. This helix replicates and passes on its information to the body's cells.
In humans, all the DNA is packaged into 46 separate molecules called "chromosomes." The chromosomes each contain thousands of genes, with each gene specifying how to make a particular protein necessary for cellular function. Scientists have long t .....

probably more important than the knowledge of the overall behaviour patterns "

.... large, clumsy, elaborate machines which needed lots of human intervention to one program on a floppy disk. When the power of computers increased, so did the possibilities of CADD.
Images on CADD systems are drawn with the aid of a keyboard, mouse, or tracking ball. One selects the starting point of a line, the ending point, and the line is drawn. A scale at the bottom of the screen tells how long the line will be. On some CADD systems, the computer itself can measure how long the line will be while the operator inputs the length of the line. Lines are the ba .....

.... to this day. this is called the theory of evolution. His book was
called “The Origin of Specie.” Alfred R. Wallace, came out with a theory
