Some molecular studies point to amphibians descending from the lung fish, the Diponi.
Under the class Amphibia, amphibians are tetra-pod, cold blooded vertebrates without having scales. Protein is produced by the special skin of Amphibians.
Lung fish belong to the subclass of Diponi, these are living air breathing species.
Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
