With the rising world population‚ we will need more food. Farmers will not be able to support the whole world with food supply. The USDA is conducting research on the cost if Atrazine is banned. "The costs of treating all surface water consumed by those living in the Midwest would be about $400 million annually. Banning atrazine would eliminate the need to incur these costs‚ but the costs to producers and consumers range between $517 million and $665 million." (USDA). The

Name____________________ Comparing Rates of Evaporation Several factors determine how fast a sample of liquid will evaporate. The volume of the sample is a key factor. A drop of water takes less time to evaporate than a liter of water. The amount of energy supplied to the sample is another factor. In this lab‚ you will investigate how the type of liquid and temperature affect the rate of evaporation. Problem: How do intermolecular forces affect the evaporation rates of liquids? Pre-Lab:

1 gram. If the mass of the beetroot cylinder varies it may cause a difference in diffusion capabilities. Length of beetroot cylinder The in order to ensure the surface area is kept the same‚ each cylinder must be 2 cm long. This should be measured using a 15cm ruler. If the lengths are different it would result in a difference of surface areas therefore questioning the test’s accuracy. Age of the beetroot To keep the age of the beetroot the same‚ the same beetroot will be used to extract the cylinders

can filter water‚ by breaking it down to biomass (the leaves and roots of duckweed)‚ and treated water. Duckweed is a simple‚ aquatic plant that consists of two-to-three small thalloids‚ or plate- like leaflets that floats on or just under the surface of the water‚ which may or may not have simple rootlets. As I have mentioned‚ the scientific name for duckweed is Lemnaceae. Lemnaceae is from the order Alismatales‚ and the family Araceae. The largest thalloids can get up to ¼ of an inch‚ while the

extrusion and rolling. The important assumptions are : 1. The direction of the applied load and planes perpendicular to this direction define principal directions‚ and the principal stresses do not vary on these planes. 2. Although effects of surface friction are included in the force balance‚ these do not influence the internal distortion of the metal or the orientation of principal directions. 3. Plane sections remain plane; thus the deformation is homogeneous in regard to the determination

What is a Wetland ? Wetlands are habitats that fall somewhere on the environmental spectrum between land and water. Since wetlands lie at the interface of terrestrial and aquatic habitats‚ they possess a unique mixture of species‚ conditions‚ and interactions. As a result‚ wetlands are among our planet’s most diverse and varied habitats. Wetlands are defined by the soils‚ hydrology‚ and species that occur within them. Wetland soils‚ also known as hydric soils‚ are shaped by water. These soils
