Detecting Genetically Modified Food by PCR
Genetic engineering is responsible for the so-called "second green revolution."  Genes that encode herbicide resistance, insect resistance, drought tolerance, frost tolerance, and other traits have been added to many plants of commercial importance. In 2003, 167 million acres of farmland worldwide were planted in genetically modified (GM) crops equal to one fourth of total land under cultivation.  The most widely planted GM crops are soybeans, corn, cotton, canola, and papaya. Two important tr

Natural Resources, the Environment and Ecosystems
This booklet contains several activities that can be used by students to become more aware of how plants, animals, and humans interact within ecosystems, and how one influences the other. The activities can be used singly with other projects, but completion of all activities should give students an understanding of how ecosystems work and how all aspects of an ecosystem are interrelated.

But is has also encouraged those countries in the EU who are not in the Euro-zone, or those not in the EU at all, to borrow in Euros as well. The point about the consolidation and integration of the Euro bond market discussed in Subsection 1.5, even though it is by no means comp
