VI. Define:

  1. Classification: Classification is the process of arranging things in groups or classes according to their resemblances and affinities and gives expression to the unity of attributes that may exist amongst a diversity of individuals.
  2. Species: Species is defined as a group of organisms that consist of similar individuals capable of interbreeding or exchanging genes among themselves.
  3. Invertebrate animals: Invertebrate is the group of animals that neither possess a vertebral column nor do they develop a vertebral column in their lifetime. It is derived from the notochord.
