Answer:
D.
Explanation:
Prokaryotic DNA exhibit single origin of replication while eukaryotic DNA has multiple origins of replication because eukaryotic DNA is much larger and multiple origin of replicate helps them to replicate the whole genome in short time duration.
Large DNA of eukaryotes contain high amount of material to be replicated and multiple origin sites helps them to replicate in short time. DNA replication initiate at each origin site independentaly and terminate at corresponding termination sites.
Hence, the correct answer is D.
D. Genes and the environment. The Arctic fox changes it's fur color for camouflage and protection purposes (Hunting prey and Hiding from predators).
The specific type of bond formation that takes place in sodium chloride is an ionic bond. The essence of how the bond eventually forms is mentioned in the question. After sodium donates it's one valence electron to chlorine, chlorine becomes negatively charged atom known as an anion while the sodium atom becomes a positively charged cation. The electrostatic attraction Between the 2 oppositely charged ions forms an ionic bond, resulting in a ionic lattice type of structure in sodium chloride.
The cause of this problem was that there was not anofe plants to release oxygen and not anofe plants to take in carbon.
