Answer:
Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.
Explanation:
The eruption of Mount St. Helens provided a prospect for the scientists to examine the effects of the catastrophe. In the eruption, the losses were tragic, however, after the incident, the geologists hugely bettered their tendency to determine eruptions, by safely evacuating thousands of Filipino people prior to the eruption of Pinatubo in 1991.
Scientists also started to learn various other valuable lessons, even some of them have defied the fundamentals of evolutionary thinking. The eruption of 1980, offered a natural laboratory for comprehending that how quickly the catastrophic procedures can reshape the globe, and how briskly wildlife can recover.
The main difference between prokaryotes and eukaryotes is the presence of nucleus in eukaryotes and its absence in prokaryotes. Also, prokaryotes are unicellular, so one cell is a whole organism. On the other hand, eukaryotes are mainly multicellular, and thus more complex. More complex DNA is inside the nucleus in the eukaryotes which enables them to conduct a wider range of functions. Prokaryotes, as a single cell, have simple functions present.
