Answer:
Both Cohesion and adhesion play an important role in the upward movement of water through a plant.
Explanation:
Water is absorbed by the roots and transported by xylem tissue to various parts of a plant body such as stem ,leaf .
During the transportation of water molecules through the xylem tissue formation of hydrogen bond occur between the water molecules. A single hydrogen bond is weak but collectively they exert a very strong interaction.As a result a water column is established in the xylem tissue. This is called cohesion.
Adhesion deals with the interaction of water column with the wall of the xylem tissue.
Answer:
Recombinant DNA
Explanation:
Recombinant DNA can be used to change the genetic makeup of a cell, as in adding a gene to make a bacterial cell produce insulin.
Answer:
B
Explanation:
Igneous rocks are formed by the solidification of magma or lava.
Considering that the roots are a form of biological weathering (so/thus) erosion (from/due to) changing weather also (disintegrates/breaks down)the rock.
