Cells within the body are properly arranged and their production uses up resources of the body. For example, red blood cells use iron while being produced. The body must dispose of cell properly to maintain the orderly arrangement of cells; for example, if dead skin cells were not removed, we would lose feeling in our skin due to the layer of dead cells. Moreover, the body must work to minimize wastage. This is why some of the iron from red blood cells is removed and reused.
The best way to reduce wind erosion on farm is to plant ground cover in unused fields.
Explanation:
- Wind erosion is defined as the removal of the top soil from unused barren land by winds.
