The following is a description of allelic frequency. In cattle, roan is a pattern of red and white which is the most prevalent. There are only a few red cows and only a few white cows. On a sheet of scratch paper develop a frequency
distribution chart that shows this. Now read the following scenarios and decide what kind
of shift has happened with the allelic frequency.
Scenario 2
Mr. Huckle, goes to the market one day. While he is out, a pack of coyotes ravage his farm.
The coyotes believed that the roan cows taste better, so those are the ones they choose to
eat, leaving the white cows and the red cows to look on in fear. Describe the allelic
frequency distribution in this scenario.

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.
