Which of the following provides the best description of a difference between prokaryotic and eukaryotic cells?
a)eukaryotic cells have cell walls that consist mainly of sugars, while prokaryotic cells do not.
b)prokaryotic cells contain chloroplasts and mitochondria, while eukaryotic cells do not contain specialized organelles.
c)the cell membrane of prokaryotic cells contains proteins, while the cell membrane of eukaryotic cells contains only lipids and carbohydrates.
d)the dna in eukaryotic cells is enclosed in the nucleus, while the dna in prokaryotic cells is not separated from the rest of the cell’s contents.

The right option is; D)The DNA in eukaryotic cells is enclosed in the nucleus, while the DNA in prokaryotic cells is not separated from the rest of the cell’s contents.

Eukaryotic cells are cells that contain membrane-bound organelles such as mitochondria, endoplasmic reticulum with a definite nucleus. Examples of eukaryotes are plants, fungi, and insects. Prokaryotic cells are cells that do not have a true nucleus or any membrane-bound organelles. Prokaryotes include bacteria and archaea. In eukaryotic cells, the DNA is enclosed in the nucleus, while in prokaryotic cells, the DNA (a single chromosome) is located in an area of the cell known as nucleoid.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
