In the fantastic Jillalope, the offspring of a true-breeding black parent and a true-breeding white parent all appear gray. When these gray offspring are crossed among themselves, their offspring always appear in a ratio of 1 black : 2 gray : 1 white. Upon close examination of the coats with a magnifier, each hair of a gray animal has closely-spaced alternating black spots and white spots, but no gray spots. What is the mode of inheritance

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.
