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.

Answer:
One of the structural barrier that a cell might have to overcome in order to go through mitosis is described below.
Explanation:
Structural barriers can be described as any of the structural changes in the structures of the body which do not allow it to perform its normal function.
The chromosomes of a cell have to arrange in a certain manner for the process of cell division to occur. Sometimes, the chromosomes might become so damaged that the normal DNA repair factory is unable to repair the chromosomes. The damage in the chromosomes might arise due to a number of reasons such as exposing to UV light or any kind of toxic chemical. To overcome this obstacle, certain extrinsic factors can be utilized to fix the damaged chromosomes. This is an example of the structural barriers which might be overcome by a cell for mitosis.
