Zoos are sometimes seen as necessary but poor alternative to a natural environment. Is it necessary to keep animals in zoos? Zoo is the place where different kinds of animals are kept‚ displayed to public‚ and in which they may also be bred. In today’s fast paced world‚ people are pressurized everyday working at a stressful job from nine to five; leisure in the form of going to zoo can be truly welcoming. There are many debates on whether zoos should be prohibited since the issue of animal conservation

Mt Henry Peninsula Population Study Mount Henry Peninsula is an area of significant biodiversity. The various plant species that are found in this region rely on a specific combination of abiotic and biotic factors. Plants found in one location may not necessarily occur in another‚ where the conditions are different. The following extract is part of a study commissioned by the City of South Perth. “The Mt Henry Peninsula and its associated foreshore is the largest area of bushland in the City

Habitat: It depends on the species as to where they live Diet: carnivore‚ eat different types of fish Reproduction and babies: Dolphins are aquatic mammals that are closely related to whales and porpoises. Dolphins evolved about ten million years ago. .. Dolphins belong to the family Delphinidae. It is the largest and most diverse family of aquatic mammals and includes 26 living species dolphins vary in size from 2m -3 metres and 150- 300 kilograms. Most species of dolphins are larger than

attached to extinction‚ and because the number of species extinctions in the history of life is almost the same as the number of originations; present-day biodiversity is the result of a trivial surplus of originations‚ cumulated over millions of years. For an evolutionary biologist to ignore extinction is probably as foolhardy as for a demographer to ignore mortality. According to Charles Darwin’s view of extinction and its role; -extinctions of species have occurred gradually and continuously throughout

schooling behavior of fishes. The objective was to investigate if fishes prefer to school with its own species. Briefly‚ a guppy was allowed to swim freely in a tank in which there were 2 beakers each containing three guppies (beaker 1) and three zebrafish (beaker 3). The times the guppy spent near beaker 1 and 3 were monitored. The null hypothesis is that fishes do not prefer to school with its own species. The results obtained show that the guppy spent 83.3% of the test period in the territory of beaker

general physical changes that occurred between several key species on the phylogeny of man‚ and a discussion of dating methods used to pinpoint the age of the fossils. This essay will begin with a brief discussion of dating techniques. In the study of hominid evolution‚ two main methods of dating are used: carbon-14 and potassium-argon dating. Carbon-14 dating involves the decay of radioactive C-14‚ which has a half life of 5770

basically as evolution within a species. This happens with minute changes that do not create new species. Almost like a better improved species. Unlike microevolution‚ macroevolution creates hole new species all together. Experiments can only really test microevolution because of the time limit. If macroevolution is almost impossible observed because of the time it takes. New genes are not required for macroevolution as long as such evolution is limited to closely related species‚ an example would be lions
