Answer: The first and the fourth figure is showing the two stages of metamorphosis in beetle. The first figure represents the adult stage of beetle and the last figure represents the larvae stage of beetle. Metamorphosis is the biological process by which an organism goes through differentiation of cells. As a result of this differentiation the structure of the organism changes from one to another. There are four stages egg, larvae, pupa, adult.
The second figure shows regeneration in cnidaria. They repair their body and reproduce asexually by this process. They show two stages polyp and medusae. Medusae have less ability to regenerate but poly stage can regenerate from small parts. This ability helps corals to heal back after being destroyed by predators.
The third figure represents cow and this is an unique feature of mammals to produce milk by their mammary gland. During the lactation period the cow produces milk that is used by cattle and human beings.
