Lake and Ocean Lifeguards: A Comparison Lake and ocean lifeguards work very similar jobs but have distinct differences. Lifeguards are trained in skills in order to protect and serve the public. The history of lifeguards is quite recent since actual lifeguards have only been around for the past 100 years. Lake and ocean lifeguards have a similar skill set, yet their distinct locations makes a major difference in what is required of them. While lake lifeguards and ocean lifeguards perform many of
There are 6.5 million species of land mammals. Wildlife biologists get the privilege of studying and spending time with these animals as their everyday life. I should be a wildlife biologist so I can study land mammals. Wildlife biology is a field of biology in which land animals are studied. It deals with all animals with backbones and studies individual species of wildlife, their habitats, and surrounding ecosystems (Fitzgerald). It also studies how animals may interact with their ecosystem. Without
Environmental science is the study of the environment (air, water, soil, organisms) and the solution to environmental challenges, for example, human activities. Although environmental science is common knowledge today, it was not a field of study until the 1960’s. Around this time, environmental science presented few issues in comparison to the many we face today. In the last few decades, humans have made damaging effects on the environment, like the ozone layer and global warming. Also the earth
Introduction Viruses are the most abundant organisms in the sea, with approximately ten billion in every litre of sea water(1, 2). Viruses are very small at generally 20-200nm, and have a simple structure consisting of genetic material with a protein coat, and sometimes a lipid envelope(2). Due to their simplicity, viruses rely on exploiting living cells and using the host’s cellular machinery to replicate(3). Irrespective of their size, viruses have been found to have a significant influence on
Science is the history of using systematic methods of study to make observations and collect facts. It covers fields of knowledge that deal with a variety subjects. The word science comes from a Latin word which means “knowledge”. Some scientists search for clues pertaining to the origin of the universe; others examine the structure of molecules in the cells of living plants and animals. Scientists investigate why we act the way we do, or try to solve complicated mathematical problems to explore
Exploring the effects of Human Activity on Soil pH and Maple Tree Growth Weston Hall Rochester Institute of Technology Abstract: Maple trees play an enormous part in the Northeastern United States economy as well as some parts of Canada. Wood from these trees is used to create quality lumber and the sites attract tourists from all over to the beautiful scene. Human activity has been proven to have a drastic effect on our natural environments. For example
The concept of the microbial loop first began in 1926 by Vernadskii, who studied heterotrophic and phototrophic microbial metabolism; and understood that these systems represented a major part of total metabolism in the oceans (Pomeroy, 1988). Older techniques that scientists used for enumerating marine bacteria were by plate counts, serial dilutions and phase-contrast microscopy. These numbers represented about 10% of actual numbers and are no longer used (Azam et al, 1983). Scientists were unable

The Effects of Mono Lake's Hydrology on its Ecosystem Situated at the foothills of the Eastern Sierra Nevada, Mono Lake has an unusual and unique hydrology that is highly influential in shaping the water chemistry (specifically the water's salinity and alkalinity) and biological life that survives there. Mono Lake is a hypersaline, highly alkaline, hydrographically closed basin in which the only natural means of water export is through evaporation. The basin itself was carved out by faulting
Thousands of years before the rule of the Inca, the Tiwanaku civilization emerged from the southern shores of Lake Titicaca and reached across the borders of present day Peru, Bolivia, and Chile. The city of Tiwananku is recognized by many Andean scholars as a major center of political, economic, and religious life, and is marked as one of the most important civilizations of the pre-Colombian Americas. Reaching its height from 500 to 900A.D, only its impressive stone monuments remain as evidence
