Which of the following describes a difference between eukaryotic and prokaryotic cells ?

Eukaryotes

DNA is bound to protein, DNA is linear, DNA usually has introns, has a nucleus, is membrane-bound, has mitosis and meiosis, chromosomes are paired (diploid).

Prokaryotes

DNA is circular, DNA not bound to protein, DNA usually doesn't have introns, no nucleus, not membrane-bound, binary fission, and single chromosome (haploid)

Explanation:

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.

a compound light microscope is used to magnify objects in steps.
