<h3>What factors about the ecology of the great plains did farmers fail to understand?</h3>
  • Environmental change has been significantly less drastic than the two-thirds of the grassland that farmers were unable to successfully plow for crops.
  • The majority of such area still has native vegetative cover, despite the fact that virtually all of it has been extensively grazed by cattle and in much smaller amounts by sheep and horses.
  • Two key climatic gradients—an east-west gradient of increasing precipitation and a north-south gradient of increasing temperature—which both produce drought—control the spread of both natural ecosystems and land use management.

There is also an tRNA, which carries the amino acids for each messenger RNA where they bind to the proper position, within the protein synthesis

topjm [15]
