Answer:
Advantage of gene expression in prokaryotes is it occurs faster than in eukaryotes because transcription and translation occur simultaneously in the cytoplasm, and regulation occurs at the transcriptional level. Whereas disadvantage of gene expression in prokaryotes is that there is no post translational modification and low expression of genes.
Explanation:
Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm. To synthesize a protein, the processes of transcription and translation occur almost simultaneously. When the resulting protein is no longer needed, transcription stops. As a result, the primary method to control what type of protein and how much of each protein is expressed in a prokaryotic cell is the regulation of DNA transcription. All of the subsequent steps occur automatically. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. whereas in eukaryotes, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein. The processes of transcription and translation are physically separated by the nuclear membrane; transcription occurs only within the nucleus, and translation occurs only outside the nucleus in the cytoplasm.

Answer:
The movement is called revolution when a body travels around another body in space.
Explanation:
The movement is called revolution when a body travels around another body in space. It is different from rotation which is a phenomenon where a body revolves around its own axis. For example, we can assume the motion of earth as revolution when it travels around the sun and completes one complete revolution in one year, on the other hand when it moves around its own axis the day and night transformation happens. We can also take the example of moon which revolves around the earth and many other planets which revolve around the sun. So it is very easy to understand the concept of revolution.
Hope it helps!
Well new species can come and live there and some animals may have new food but the disadvantage is some of the animals ill die that lived there because of the changes...i hope this helped you
