The role the native grasses played in the environment
That local weather patterns were subject to periodic drought
<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.

Answer:
The correct answer is option A
Explanation:
Hypoparaghyroidism occurs when thyroid gland produce little parathyroid hormone.
This is caused by:
1. Injury to the parathyroid glands during thyroid and neck surgery.
2. It is also caused by auto immune disorder. This is as a result when the body's natural defence against invading organisms starts to attack perfectly healthy tissues.
3. Congenital defects: This is as a result when infants are born without parathyroid tissue, that is ability to make thyroid glands or when the mother has hypoparathyroidism.
Segments of genetic information, segments of nucleotides present in a particular strand of DNA, have the coding instructions to eventually synthesize proteins or polypeptides in the cell.
