5. Which of the following statements describes processes that occur during DNA replication?
A. A DNA sequence is read by RNA polymerase, which produces another
RNA strand complementary to the first strand.
B. Two free-floating single strands of DNA are joined by polymerase. The
polymerase finds the point at which the two strands will match up into a
double strand.
C. Messenger RNA are decoded by a ribosome to produce an amino
acid chain. In the cell's cytoplasm, transfer RNA joins the messenger RNA,
forming a polypeptide.
D. A double-stranded DNA molecule is unwound into single strands.
Polymerase matches the right nucleotides to the single strand so that
each forms a double strand of DNA.

A double-stranded DNA molecule is unwound into single strands. Polymerase matches the right nucleotides to the single strand so that each forms a double strand of DNA.

Explanation: During replication, a double-stranded DNA molecule is unwound by an enzyme known as helicase into two single strands of DNA that serve as templates for new strands of DNA.

Then another enzyme known as DNA polymerase matches the free and right nucleotides to the nucleotides on the single DNA strands (templates) to form a double-stranded DNA molecule.

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.
