Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
The statement that best explains the reason for the general trend in hominid evolution that occurred over millions of years is that; Hominids evolved to walk upright on their hind limbs, reducing the need for opposable toes. Hominids are the members of the family Hominidae; which includes humans and the great apes. There has been a continuous evolution in this class from the first hominids to the current human, which has seen a lot of change from the foot, the brain capacity, activities involved, among other features.
