Answer:
B) Absence of native grasses
Explanation:
The grasses, which acted as a windbreak and whose roots anchored the soil in place, were overgrazed and/or removed to allow for farming. Once a few years of severe drought affected the area, any wind storm was able to blow the topsoil away, rendering the farm land of the Great Plains virtually unusable in many areas. Ground cover is an essential part of sustainable agriculture.

Answer:
Explanation:
What occurs when the stomata close and evaporation stops is that, the tension in the xylem continues to increase until the living cells of the leaf are fully hydrated. This happens according to the cohesion-tension theory of sap ascent.
This happens at night. Transpiration stops immediately when the stomata is closed. There is a cohesion between each water molecule and adhesion between the water molecules and the stem walls; water is held in the leaves ad stems when the stomata is closed this hereby increases the tension.
The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.
<h3>How to calculate amount of landscaping plants?</h3>
just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
<h3>How to calculate the spacing between plants?</h3>
If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).
With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
