Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occurs simultaneously. Which of the following is the most probable reason for this observation?
Prokaryotic DNA is much smaller than eukaryotic DNA.

Prokaryotic DNA is much smaller than eukaryotic DNA.

Explanation:

Prokaryotes are microscopic and simple organism and their genetic material is very much smaller than eukaryotes. So as the DNA of prokaryotes is smaller therefore only one origin of replication is sufficient to replicate the DNA in them on time.

As eukaryotes have much larger DNA so one origin of replication is not sufficient to replicate the DNA of eukaryotes until the cell cycle completes, therefore, to complete the DNA replication at the time the DNA must have multiple origins of replication.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
