The best answer is the third option namely an enclosed nucleus.
One major difference between these two types of cells is that a prokaryote cell has no distinct nucleus enclosed with a membrane whereas in a eukaryote cell the genetic material, which is DNA, is packaged into chromosomes and found within a distinct nucleus that is enclosed with a membrane
Examples of prokaryotes are bacteria such as staphylococcus species found as commensals on the skin of man and Streptomyces soil bacteria from which the antibiotic streptomycin is derived.
Examples of eukaryotes are an amoeba, which is a unicellular protozoan that lives in water and a hepatocyte which is a liver cell in man.
Answer:
Semi-Conservative
Explanation:
After DNA replication, the parental DNA molecule contains two original DNA strands while the daughter molecule is composed of two newly synthesized strands. In this model, the two DNA strands in the parental molecule separate from each other and serve as templates for the synthesis of daughter strands.
Explanation:
because it allows you to eliminate or isolate variable/ it allows the experiment to minimize the changes in all the variables except the one being test.
I'm not gonna choose bc I'm not 100% sure either so read what's above, think it over and choose wisely
