For example, the mid-range nitrogen fertilization for bahiagrass is 125 pounds and the corresponding carrying capacity is 1.0 AU per year. In this instance, the cost of the bahiagrass will be $123 per acre and the annual cow cost for bahiagrass pasture would be $123. Conversely, at the high rate of 150 pounds of nitrogen per acre and a carrying capacity of 1.5 AU per acre, bermudagrass has cost of $208 per acre and a cow cost of $139 per cow per year.
Polar Bond Definition: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed.This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.Polar bonds are the dividing line between pure covalent bonding and pure ionic bonding. Examples: Water is a polar bonded molecule.his causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative. Polar bonds are the dividing line between pure covalent bonding and pure ionic bonding. Examples: Water is a polar bonded molecule.
Water is not the only molecule that can have polor covalent bonds. Examples of other molecules that have polar covalent bonds are Peptide bonds and amines. The biological consequence of polar covalent bonds is that these kinds of bonds can lead to the formation of a weak bond called a hydrogen bond.xamples of other molecules that have polar covalent bonds are Peptide bonds and amines.
