Answer:
Since genetically engineered (GE) crops were introduced in 1996, their use in the United States has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009. To date, crops with traits that provide resistance to some herbicides and to specific insect pests have benefited adopting farmers by reducing crop losses to insect damage, by increasing flexibility in time management, and by facilitating the use of more environmentally friendly pesticides and tillage practices. However, excessive reliance on a single technology combined with a lack of diverse farming practices could undermine the economic and environmental gains from these GE crops. Other challenges could hinder the application of the technology to a broader spectrum of crops and uses.
Explanation:
Answer:
- The geography of the continents (they fit each other, contain similar mountain ranges, etc)
- The distribution of fossils and rocks
- The locations of ancient climatic regions
Explanation:
The continental drift theory states that continents moved across geologic time, plowing through oceans and drifting to different parts of the planet. The continental drift theory is associated with Alfred Wegener, who the first in using this terminology in 1912. Some of the most important lines of evidence that support the continental drift theory are the movement of continents on tectonic plates, the presence of evolutionarily related plant and animal fossils in different continents, paleoclimate indicators (e.g., glacial striations), etc.
