Killer Whale, The Mighty Dolphin
Number of words: 399 | Number of pages: 2.... soon found that fishermen were shooting them to keep them from eating all of a days catch. This was not the first time something like this was found. In the 1950's The U.S. Navy used machine guns to slaughter hundreds of Killer Whales off of Iceland to protect fishing. After these animals are killed, they are usually thrown away. The meat is very bitter and is not used. Killer Whales also do not produce oil as most other whales do so there is no benefit from that area of trade either.
Killer Whales aren't actually whales, they're dolphins, the largest of their group. Both Dolphins and Killer Whales are extremely intelligent and le .....

Greenhouse Gases And Consequences
Number of words: 1452 | Number of pages: 6.... for life to exist. There is, however, one problem: human activity has dramatically increased the amount of greenhouse gases in the atmosphere.
Over the last two centuries the concentration of greenhouse gases in the atmosphere has increased quite significantly, mainly as a result of burning fossil fuels for industrial purposes. For example, atmospheric concentrations of carbon dioxide have increased from 280-285 parts per million in 1800 to 350 parts per million today. Currently the concentration of CO2 is rising by 0.4% per year. Methane has increased from about 750 parts per billion to 1700 parts per billion over the past 200 .....

The medications that are discussed in the case study are bronchodilator inhalers (such as ventolin) and Cromolyn (Appendix 1). Bronchodilators are asthma relievers and there are three types: Sympathomimetics, which are similar to epinephrine hormones in a person's body also known as adrenaline, which is released when the body is under stress. This drug is related to the "fight of fligh .....

Factors Of Parasitic Virulence
Number of words: 2924 | Number of pages: 11.... cited (Esch and Fernandez 1993, Toft et
al. 1991) are evolutionary history and mode of transmission.
Incongruently evolved parasite-host associations are characterized by
high virulence, while congruent evolution may result in reduced
virulence (Toft et al. 1991). Parasites transmitted vertically (from
parent to offspring) tend to be less virulent than parasites
transmitted horizontally (between unrelated individuals of the same or
different species). Studies in which virulence is shown to increase
during parasite-host interaction, as in Ebert's (1994) experiment with
Daphnia magna, necessitate a synthesis of tra .....

Genetic Engeneering
Number of words: 815 | Number of pages: 3.... and amount grown would increase. Another area of genetic technology involves inserting genes into plants to make them immune to common viruses, this could increase the crop production. If the crop production could be increased, food would become cheaper and easier to obtain. For economical reasons gene technology is better for the producers and consumers. The producers wouldn’t have to throw some crops away due to disease and weather damage, and we the consumers would get better quality foods for a smaller price.
More food could be created with the use of genetically engineering therefore solving some of the world hung .....

Coral Reefs And Bleaching Phenomenon
Number of words: 1422 | Number of pages: 6.... size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter for fish and marine invertebrates. While the coral itself is an animal, through a symbiotic relationship with the unicellular algae, coral becomes the primary producer in its ocean ecosystem (Richmond 1993). The reefs are formed by calcium carbonate deposits produced by the coral polyps. According to the legendary Cousteau, in his book The Ocean World, tube worms and mollusks also donate their hard skeletons to the architecture of the growing reef (174). Biologically active compounds are also produced by re .....

Reproduction: A Courting To Nature
Number of words: 967 | Number of pages: 4.... to describe the behavior of these large, social birds.
At the same time he did not forget that all romance - animal and human - is
tied intimately to natural selection. Natural selection brought on the
evolution of males and females during prehistoric epochs when environmental
change was making life difficult for single-sex species such as bacteria
and algae. Generally, these reproduced by splitting into identical copies
of themselves. New generations were thus no better than old ones at
surviving in an altered world. With the emergence of the sexes, however,
youngsters acquired the qualities of two parents. This mean .....

Charles Darwin And Richard Owen
Number of words: 3241 | Number of pages: 12.... in the cataloging of a collection
containing thirteen thousand specimens (known as the Hunterian Collection (Rupke 17)). It was probably this that
lead Owen interest in the field of anatomy, which eventually lead him into becoming a naturalist. By 1836, he
published anatomical work on the Memoir on the Pearly Nautilus (Rupke 119). Within a year, he was giving
lectures to the public on the the Hunterian Collection. These lectures were often attended by important and
royalty figures of Victorian England. Charles Darwin was also one of the many that attended Owen's lectures.
His death in 1892 was treasured with a br .....
