What are the differences between prokaryotic and eukaryotic cells?

The main difference between a eukaryotic and a prokaryotic cell is the presence of a nucleus and organelles in the eukaryotic cell and their absence in the prokaryotic cell. The absence of nucleus and membrane-bound organelles classifies organisms as prokaryotes.

Prokaryotic DNA is not inside a membrane, it is short-stranded and free in a cytoplasm. In eukaryotic cells long tangled strands of DNA is packed in the nucleus and because of the length it is organised in chromosomes. 

i think the answer is

mass

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
