Bt-corn and its Effects on Danaus plexippus Recently‚ in response to the chronic problem of insects destroying crops and from the known effects of pesticides on humans and on the environment‚ a new form of insecticide was discovered‚ particularly for corn. In this new case‚ the organism itself is genetically modified for protection. This insect-resistant corn is the new Bt-corn and contains genetic material from the donor organism‚ a bacterium. Bacillus thuringiensis contains a protein that kills

expectations. One vegetable that this is especially true of is corn. Helicoverpa zea or corn earworms aren’t a very appetizing idea to think of‚ yet they are a relevant part of corn production today. This fact became evident to me after working for the maize breeding department this past summer. Around each field the department plants sweet corn as a border crop‚ and once it’s time to harvest‚ everyone can bring home a few ears of corn. Almost every ear has an earworm that you must remove before the

When the Sony TV price decreases from LE 1‚000 to LE 800‚ consumers increases their quantity demand from 100‚000 units / month to 120‚000 units / month. Calculate the price elasticity of demand (PED). Also

Laws of Supply and Demand The market price of a good is determined by both the supply and demand for it. In the world today supply and demand is perhaps one of the most fundamental principles that exists for economics and the backbone of a market economy. Supply is represented by how much the market can offer. The quantity supplied refers to the amount of a certain good that producers are willing to supply for a certain demand price. What determines this interconnection is how much of a

explain the concepts of price elasticity of demand‚ income elasticity of demand and cross elasticity of demand. Income elasticity of demand measures the responsiveness of demand to a change in income‚ ceteris paribus. It is the percentage change in demand for a good resulting from a percentage change in income‚ ceteris paribus. When income changes with other price or non-price factors‚ such as income‚ remaining unchanged‚ income elasticity of demand measures how much to which demand will change‚ ceteris

estimate elasticity of demand. If there is no switching cost between lens and medicine‚ under any price above WTP‚ farmers will choose only medicine. On the other hand‚‚ farmers will chose only lens at any price below WTP. Therefore‚ demand curve is perfectly horizontal. If we assume there is some switching cost‚ and the cost is different from farmers‚ demand increase when price goes down. If we assume liner demand curve‚ we can say slope of demand curve is negative. Still‚ at the price of WTP‚
