Cohesion; the water molecules attract each other and are responsible for the surface tension of water.
Adhesion; the water molecule is also able to attract other non-water molecules. This allows water to be able to ‘cling’ to the sides of a capillary tube.
The complementary action of these two forces allows water to rise in a narrow capillary tube such as the xylem tissues of plants.
Decreased surface-to-volume ratio. The dolphin's fusiform body shape and reduced limb size decrease the amount of surface area exposed to the external environment.
Increased insulation. Dolphins deposit most of their body fat into a thick layer of blubber.
The information needed would be found on mRNA that is transcribed from a section of DNA. The mRNA is translated by the ribosome into the product polypeptide based on the sequence.
