The Origin Of Life
Number of words: 1419 - Number of pages: 6.... of the fittest" can be taught in schools, versus religious belief of Divine creation. From 1920 to 1986 the argument continues in the courtroom, and many, many books have been written debating the issue.
Let us look at the three theories in depth. The evolutionist theory made known by Charles Darwin, states that humans came from his theory “survival of the fittest.” Charles Darwin based his theory on individual chances that determined the fate of the species. “Charles Darwin as we recall based his explanation of natural selection among individuals with equal .....

Endangered Species 2
Number of words: 3779 - Number of pages: 14.... at the Wolong centre.
In addition to experience gained over the years at Wolong, the recent success of births can be attributed to improved cooperation between China's Ministry of Forestry and the country's zoos involved in panda breeding, as well as to an exchange of information and technology between Chinese and western scientists.
Some problems are, however, still experienced with animal husbandry, particularly the care and welfare of infants. Disease and rejection by the mother have been the main cause of death among cubs. Investigation of these, and other .....

The Big Bang
Number of words: 1283 - Number of pages: 5.... still expanding, as astronomers have observed.
The Steady State model says that the universe does not evolve or change in
time. There was no beginning in the past, nor will there be change in the
future. This model assumes the perfect cosmological principle. This principle
says that the universe is the same everywhere on the large scale, at all times.2
It maintains the same average density of matter forever.
There are observational evidences found that can prove the Big Bang model
is more reasonable than the Steady State model. First, the redshifts .....

Early Synthetic Polymers
Number of words: 573 - Number of pages: 3.... chemically altered. Scientists first started to make them in the second half of the nineteenth century, long before we really even knew what a polymer was. The very first came about when a scientist reacted cellulose, in the form of cotton, with nitric acid. The result was cellulose nitrate. Cellulose nitrate, also called gun cotton, turned out to be a powerful explosive. It soon replaced common gunpowder as the explosive charge in the ammunition for rifles and artillery.
Cellulose nitrate was also used to make an early polymer containing composite material, s .....

Predator - Prey Relationships
Number of words: 4238 - Number of pages: 16.... animal or animal of the other
population(Boughey 1973). No known organism escapes being a victim of
parasitism(Brum 1989).
Parasitism is similar to preditation in the sense that the parasite derives
nourishment from the host on which it feeds and the predator derives nourishment
from the prey on which it feeds(Nitecki 1983). Parasitism is different from
most normal predator prey situations because many different parasites can feed
off of just one host but very few predators can feed on the same prey(1973). In
parasite-host relationships most commonly th .....

Acid Rain
Number of words: 766 - Number of pages: 3.... what is known as . The negative effects has on the environment is the main reason legislation of industrial emissions from governments has been prompted.
is harmful to the environment because of its low pH. It can harm the biotic components of earth, and also the abiotic components. It's high acidity degrades soil to the point where it cannot support any type of plant life. Trees in forests are killed over long-term exposure. When these trees are killed, an imbalance in the hydrologic cycle can occur. Without living trees to consume the precipitate, it must be .....

The Problem Of Global Warming
Number of words: 457 - Number of pages: 2.... we are allowing for more of the
carbon to be exposed into the atmosphere.
Another factor that most people would not consider in the raising of
global warming is the excrement of cows. Cows produces tons of carbon that does
not all get treated for, and is in the top five for highest amounts of carbon
produced per year. This is another factor that somehow has to be dealt with.
All of these causes of global warming have been know by scientists, it's
the effects we are seeing in today's climate now they had no idea of. Arctic
glaciers are melting and causing .....
