These interactions have evolved over millions of years to become an incredibly complex web of inter-species relationships and understanding these relationships enables science to model future species interactions (Abrams‚ 2000). From symbiosis to parasitism‚ Earth seems to have every type of relationship imaginable (Dietl and Kelley‚ 2002). One of the most intriguing and commonly studied relationships is that of predator and prey. The predator-prey relationship can manifest itself in many forms‚ be

Tyler Fitzgerald 10/3/08 Science Fair Research Paper The science project to be researched and experimented is whether bacteria can become resistant to antibacterial soaps. Bacteria will be grown in an agar broth containing .01%‚ .1%‚ .5% and 10% antibacterial soap. To fully understand the subject‚ information on everything necessary to conduct this experiment and comprehend the results was researched. Once the experiment is completed a conclusion will be able to be made as to whether

Bacteria are the most ancient life forms‚ most bacteria are so small that under a light microscope you can only see them as little dots. Some groups however grow to larger sizes and have spectacular shapes (1). Bacteria are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and the live bodies of plants and animals (2). Bacteria is mostly thought of as a pathogen‚ while it is true that

AP Biology Summer Assignment Chapter 50.1: An Introduction to Ecology and the Biosphere Ecology is the scientific study of how organisms interact with the environment. When studying Ecology scientists want to know‚ where organisms live‚ why they live there‚ and how many are there. Ecology and environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting
