Answer:
<em>The correct option is B) Capillary action, when adhesive forces are stronger than cohesive forces.</em>
Explanation:
When water leaves from the leaves of a plant through events such as transcription, a gap is produced in the capillary action of the xylem tube. As a result, more water is drawn from the roots to fill the void. The forces of attraction between the water and the xylem tube are much greater than the intramolecular forces of water. As a result, the water flows in an upward direction due to these string adhesive forces present between the water and xylem tube.
MRNA is needed in the cells because it directs the synthesis of proteins which is found in the cytoplasm. It is a molecule that carries the message contained within DNA to the ribosome. The Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide.
The answer is B. I hope it helps.
