Each species were separated into their own six containers‚ four of which had chemicals added into them while the other two were left as is to be a constant. All species had their population calculated every day and their behavior observed. The initial reactions to the chemicals were observed as well and noted down for further evidence. The results were placed on tables and graphs to compare species reaction. Analysis of the data revealed that the first

instead these wilds types are sources of resistant genes that can be introduced into plants that do produce fruits that are marketable. One such fruit that is being attacked by numerous pathogens is the tomato (genus Lycopersicon has 10 different species)‚ and efforts are underway in many countries and by many commercial companies to breed new lines of tomatoes that incorporate resistance to many of these pathogens.

Abstract This experiment tested the hypothesis that the pure algae populations of Ankistrodesmus and Chorella will show growth in the number of organisms‚ and the mixed population will establish a dominant species. Each population should also reach its carrying capacity. All of the populations had the same resources available. The sampling of 0.5ml of each population was used to count the number of organisms. A Neubauer slide and microscope will be needed to do this. From this count‚

influences other fields of science. Linnaeus based his science on a firm terminology‚ which formulates the concept of species and sets the broad dimensions of natural history. For example humans in this system are known as Homo Sapiens and are the primates class of mammals and Mammalia are all concepts from Linnaeus. In the early eighteenth century scientific name for species were already in Latin but most were often long and awkward. Linnaeus’ idea was to divide nature into separate groups based

There are three accepted living species of Trichechidae‚ representing three of the four living species in the order Sirenia: the Amazonian manatee (Trichechus inunguis)‚ the West Indian manatee (Trichechus manatus)‚ and the West African manatee (Trichechus senegalensis.

Rainforests February 18th‚ 2013 Mr. Zanardo AJ D’Orazio CGF 3M Grade 11 Rainforests are the oldest living ecosystems on earth. They only cover about 6% of the Earth surface but they contain more than half of the world’s animal and plant species. Rainforests are described as a tall but dense jungle. It is called a “rain” forest because of the high amount of rainfall it gets per year. There are two different types of rainforests Tropical and Temperate. A tropical rainforest is located

change when new species develop from existing species. On genetic terms‚ evolution is any change in the frequency of alleles in a population. Charles Darwin was an Englishman who was fascinated with nature‚ otherwise known as a naturalist. Darwin began a long voyage to explore the natural world. He collected fossils and sketched several animals. From this‚ he created the theory of evolution. A common ancestor is the most recent ancestral form or species from which two different species evolved. Evolution

Diversity Index Lab Introduction: The measure of the biodiversity of organisms in a given area is known as the diversity index. The diversity index values will vary between 0‚ which would indicate no diversity‚ and 1‚ which is very diverse. Any values above 0.5 usually indicate a relatively diverse population. For example‚ a healthy forest or woodland should have a diversity index of 0.7. An area that is not very diverse‚ like a cornfield‚ might have a diversity index of 0.02 or less. In this

HCP also known as Habitat Conservation Plan is a plan under the Endangered Species Act that aims to allow development from private sectors‚ landowners‚ and government‚ but at the same time also provide conservation to the environment. The plan is designed to protect habitat and to assist in species recovery on public and private property. Even though many claim that habitat conservation plan is effective in providing economic growth and conservation in urbanizing areas‚ there are still many conflicts
