(b) what major biological concepts, in
addition to evolution and ecology,
are unifying principles shared between
the two diciplines?

Biology can simply be described as the study of living organisms. Biology is divided into many sub categories depending on the features of life that we want to study. For example, molecular biology is the study of molecules which make up living organisms.

Zoology can be described as a branch of biology under which animals are studied. The field of zoology involved studying the taxonomy of animals, their evolutionary histories, physiology, embryology etc. All these studies are  parts of biology hence zoology and biology are related.

Apart from these other unifying principles shared between zoology and biology are genetics, cell biology, population biology,biochemistry etc.
