Based on the evolutionary strategies, species can be r-selected or K-selected. The characteristics of K-selected species are: large size of organisms, long lifespan, late maturity, few offspring, etc. On the contrary, the characteristics of r-selected species are: small size of organisms, short lifespan, early maturity, many offspring, etc
Sediment is natural earth material. It consists of soil particles of all sizes ranging from the smallest, “silt (mud) and sand”, to larger sizes which include the gravels, cobbles and boulders. Sediment also includes extremely hard and very large materials (bedrock) and very small tightly compacted materials (clay). All of these materials succumb to the forces of erosion from water, wind and pressures caused by expanding and contracting forces. A stream contains a certain variety of sediment based upon its geology, topography, precipitation rates and other factors in the watershed. The study of the land and water interactions is called “fluvial geomorphology”.
Answer: One difference is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. Another difference is that eukaryotic cells have many membrane-bound organelles while prokaryotic cells have no membrane-bound organelles.
