The hypothesis here is that it is the quality of the light, not the quantity of the light that makes a difference, and having a lot more light will not necessarily make photosynthesis occur any faster. Discussion With an experiment like this there is always room for error. Measurements taken incorrectly is the biggest problem, because there are multiple steps to be taken each time the light source is moved, and

1. Introduction Lichens are commonly used as ecological signs or bio-indicators. If atmosphere is extremely contaminated with sulphur dioxide there could be no lichens existing, just eco-friendly algae might be identified. When the atmosphere is clear, shrubby, hairy as well as, leafy; lichens turn out to be plentiful. A small number of lichen varieties can put up with extremely high degrees of air pollution and therefore are generally seen on pavements,

5%. Symptoms were prevelent enough to require the same kinds of injections one would get in high mountain climbing. The CO2, however, fluctuated daily probably because of a different manner in which drawdown during sunlight interacted with night respiration. The crew had to constantly monitor and tweak these levels, often by manipulating irrigation, cutting and storing biomass, and increasing or decreasing photosynthesis. Some thought that this unplanned fuxuation came about

2005). The rules for deep-sea life are different than those for terrestrial species. Stratification plays an important role in species classification in vent environments. As the chimney grows in height the environment changes. Tarasov and associates believe that deep-sea vents have a longer evolutionary history then shallow vents found closer to the surface. This is an important factor in understanding how hydrothermal vents are connected to early life on planet

China -- Globalization and Air Pollution Because China has essentially become, as The New York Times explains, " ... the world's factory floor" by producing electronics, clothes and many other goods for America and other nations (as part of its globalization strategy), it has generated "huge emissions of pollutants" in the process. Those pollutants include sulfur dioxide, nitrogen oxides; and certainly the burning of fossil fuels in Beijing and other major
