1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

Does Human-Produced Carbon Dioxide Contribute to Global Warming? There are always two sides to an issue. This is especially true in Science. Each side will gather facts and statistics to help their argument. They will also fuel the argument with their opinions. Some articles are more persuasive in their reasoning then others. This persuasion can ultimately change a person’s opinion of the issue. The question to be answered is does human-produced carbon dioxide contribute significantly to

INTRODUCTION Background of the Study Seagrasses are the marine flowering plants. They are the only angiosperms that successfully grow in tidal and subtidal marine environment. Seagrasses belong to the families‚ Hydrocharitaceae and Potamogetonaceae and they are in no way related to the terrestrial grasses of Poaceae. There are 13 genera and 58 species available all over the world. Of these‚ six genera (Amphibolis‚ Heterozostera‚ Phyllospadix‚ Posidonia‚ Pseudalthenia and Zostera) are mostly restricted

persistent. High levels of atmospheric carbon dioxide‚ caused mainly by the burning of fossil fuels‚ are absorbed by the oceans‚ where the gas dissolves into carbonic acid. This elevated acidity inhibits the ability of marine animals‚ including many plankton organisms‚ to create shells‚ disrupting life within the very foundation of the ocean’s food web. Widespread deforestation in the Amazon forest and the melting of the ice cap in Antarctica is an example of this‚ since‚ all raw materials that aid

The idea of an ocean’s surface with a red hue may seem like a very amazing phenomena but in fact it’s quite the opposite. Red tides are becoming more and more harmful to not just the sea life it’s consumes but to us humans as well. When we use pesticides and other man made chemicals‚ we are washing them away without a care of what happens next. In doing so‚ they are eventually ending up back into our oceans and cause these harmful algal blooms‚ known as Red Tide. Most of these algal blooms are toxic
