What characteristics distinguish prokaryotic and eukaryotic cells A. Eukaryotes have membrane-bound organelles; prokaryotes do not B. Eukaryotic chromosomes are linear; prokaryotic chromosomes are circular C. Prokaryotic DNA is naked or nearly naked; eukaryotic DNA is usually heavily associated with protein D. All of these are correct

D

Explanation:

Eukaryotes are defined as having membrane bound organelles. If they don't have these it is a prokaryote. Prokaryotes have circular chromosomes called plasmids, eukaryotes have linear chromosomes. Prokaryotic DNA is not protected as there are no membrane bound organelles to protect it. Eukaryotes transcript DNA to make proteins.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
