... was not needed.
The problem in keeping a creature such as the Woolly Mammoth in a zoo-
like surrounding would be poachers. Due to the endangerment of such a
magnificent species, poachers of pelts and ivory would most certainly be after
it's huge tusks and thick furs, so it would be necessary to post guards around
it's cage at all times.
A large-scale habitat would be constructed for this creature since,
during the period it lived, the Pleistocene, there were no restrictions on the
places it could roam to. There was nothing stopping this beast from stomping
along to wherever it wanted to go. A Wo ...

... traits from generation to generation. Mendel followed traits
for the P generation, F1 generation, and F2 generation. The P generation is the
original true-breeding parents. Their hybrid offspring is the F1 generation,
the first filial. The F2 generation is the second filial and is the self-
pollination of the F1 hybrids. It was predominantly his research on the F2
generation that led to Mendel’s Law of Segregation and Law of Independent
Assortment (Campbell, 1996).
Mendel’s Law of Segregation states that alleles sort into separate
gametes. He formed this through performing monohybrid crosses. ...

... allowing for photographic-quality images, interactive video conferencing and other business multimedia uses" (Inman News Features 1). It's becoming possible to transmit audio, video and data signals over great distances using these fibers of pure glass or plastic.
Today, fiber optic technology has almost become a necessity in everyday business. Because fiber optics can simultaneously transmit two audio signals across a single fiber optics cable without interfering with each other (Nelson, Garat, Wong 1), many companies have changed, or are in the process of changing their connections to fib ...

Crystals

... from the evaporators to the ‘pan.’ The pan is essentially a simple vacuum evaporator in which the removal of water continues until the concentration is appropriate for crystallization. As this proceeds, juice continues to be drawn into the pan in order to maintain a supply of crystallizable sugar. The concentration of impurities increases in the syrup as sugar is withdrawn by crystallization, and the entire boiling mass stiffens as the viscosity increases and the quantity of grows. These two factors determine the termination of the strike, since the deposition of sugar on the growing is i ...

Human Cloning

... did not receive one and this is only one organ in one country that were talking about. Statistics show that nearly one third of the patients on the waiting list for organs will die and even if they do receive an organ the human body has the tendency to reject organs which can cause serious illness or death. If we cloned human organs we would be eliminating a major killer of humans and if the organ was rejected by the patients body we could simply make another one to suit the patient. This would mean fewer complications, little or no waiting lists and almost no deaths because of organ shortages.

The Origin Of Life On Earth

... of our planet. The bulb had a heating unit under it to stimulate evaporation, then there was a smaller bulb that contained electrodes, simulating lightning and other static discharges, the evaporated water and gasses rose into this electrified bulb and were occasionally energized. The vapor then flowed into a condenser, and finally back into the simulated seas. The project was extremely simple, yet the results in a matter of weeks, was astonishing. The liquid turned the color of tea, and a black film formed on the inside of the “ocean” bulb. When the liquid and film was tested for its contents t ...

DNA

... is one
of several nitrogenous bases. DNA contains four nitrogenous bases. The first two,
adenine and guanine, are double-ringed purine compounds. The others, cytosine
and thymine, are single-ringed pyrimidine compounds. (Miller, 141) Four types of
DNA nucleotides can be formed, depending on which nitrogenous base is involved.
The phosphate group of each nucleotide bonds with a carbon from the deoxyribose.
This forms what is called a polynucleotide chain. James D. Watson and Francis
Crick proved that most DNA consists of two polynucleotide chains that are
twisted together into a coil, forming a double ...
