The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
The morphology is an example of convergent evolution.
Convergent evolution refers to the observation that unrelated species can evolve independently to present similar characteristics. The result is that species with different lineage evolve similar structures, forms, organs or in general adaptations. An example could be the fact that insects, bats and birds (even though not related) have similar structures in order to achieve flight.
They both provide energy for the body. They both occur in the muscle cells.
