Butterflies and moths have large eyes and one pair of antennae. Butterfly antennae are thin with a thick section at the tip. Moth antennae are thin all the way to the end, or have lots of side branches so they look like feathers. Other Physical Features.
How is Plasminogen Kringle 5 abbreviated? PK5 stands for Plasminogen Kringle 5. PK5 is defined as Plasminogen Kringle 5 very rarely.
Definition of pK. pK is a negative logarithmic scale of any rate constant. One of the most important examples of pK is pK a, the scale of relative acid strength. pK a is the negative log of the acid dissociation constant (pKa=-log([A-][H+]/[HA])).The Henderson-Hasselbalch equation relates pK a and pH to the relative concentrations of an acid and conjugate base in solution (pH=pKa+log([A-]/[HA])) .ne of the most important examples of pK is pK a, the scale of relative acid strength.
