How can one tell if a reaction has reached equilibrium?
o

b. the concentrations of products and reactants stop changing.
o
c. the concentrations of products and reactants are equal.
o
d. the reaction stops once the reactants have been used up.

C. The concentrations of products and reactants are equal.

Explanation:

A reaction has reached equilibrium when the concentrations of products and reactants are equal.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
