B
Area B of the graph shows the activation energy required if an enzyme was not present
Explanation:
Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.
Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.

The answer is extrachromosomal, or cytoplasmic, inheritance,
or non-Mendelian inheritance. An example in humans is mitochondrion inheritance.
Mitochondria are only passed from mother to offspring since only the egg has mitochondria while sperm does not. The name of the German scientist who
discovered this type of inheritance was
called Carl Correns.
