While you are waiting for 10 minutes‚ calculate the surface area‚ volume‚ and surface area to volume ratio for each of the 3 potato cubes (cells). AFTER 10 Minutes 5. Carefully remove the potato cubes (cells) from the iodine solution and place them on absorbent paper towels. 6. Cut each cell in half and observe

Environmental impact of mining The environmental impact of mining includes erosion‚ formation of sinkholes‚ loss of biodiversity‚ and contamination of soil‚ groundwater and surface water by chemicals from mining processes. In some cases‚ additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Besides creating environmental damage‚ the contamination resulting from leakage of chemicals also affect the health of the

increases surface runoff since there is less oppurtunity for rainwater to sink into the ground. .Retarded or supressed infiltration accelerates overland flow production‚hastening delivery of rainwater into streams and rivers‚ the oftentimes the water ends up as floodwater into the ocean‚ especially for an archipelagic country like the Philippines. Forest denudation also deprives recharge of groundwater aquifers since there is less oppurtunity for water to linger in the ground surface to infiltrate

Surface Area to Volume Ratio and the Relation to the Rate of Diffusion Aim and Background This is an experiment to examine how the Surface Area / Volume Ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen

To investigate the relationship between surface area : volume ratio and heat loss. INTRODUCTION: The aim of this experiment is to investigate and find the relationship between heat loss (of water) and surface area to volume ratio of animals. To investigate this‚ we are going to use three flasks of different volume (as the equivalent the animals) and thus different surface areas filled with water. BACKGROUND: Surface Area : Volume Ratios We will be using the following formula for calculating

description of water pollution.) A major source of non-point water pollution in the urban environment is storm water runoff‚ in the past it was acceptable for this runoff to be channeled into the natural systems of washes‚ creeks‚ and rivers. However‚ this is no longer true‚ the Clean Water Act of 1972 and the Water Quality Act of 1987 set standards for water discharged to local surface water‚ and established fines for discharges that exceed the limits. (As in the Clean Water Act Forum). Additional

Surface Water Pollution Freshwater makes up less than three percent of earth’s water‚ but is the source of virtually all drinking water.55 percent of that water comes from reservoirs‚ rivers‚ and lakes‚ These sources‚ called surface water‚ are vulnerable to pollution discharged out of pipes and precipitating out of the air but the primary source of their pollution today is runoff‚ pollutants washing off the land. These nonpoint or scattered sources are not easily traceable. fertilizers used
