Hunting reduced the population of northern elephant seals to as few as 20 individuals at the end of the 19th century. their population has since rebounded to over 50,000, but they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted. how is the lack of genetic variation related to the hunting episodes of the 1800's?

The answer is A) Genetic drift occurred: the few individuals left behind were the seals that passed on that specific gene pool.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

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.
