An increase in temperature affects the reaction rate by decreasing the velocities of particles that collide in the reaction. increasing the number of molecules that have sufficient kinetic energy to react. increasing the number of molecules that have sufficient potential energy to react. decreasing the energy that particles need to overcome the energy activation barrier.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. an incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is homozygous for blue feathers. purple offspring result. then, two of the purple offspring are crossed. according to the punnett square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete dominance? 1 in 4 2 in 4 3 in 4 4 in 4
