The graph represents the changing levels of enzymes involved in urea synthesis during the development of a tadpole. The graph depicts a transition from:
Aminotelism to Uricotelism
Ammonotelism to Ureotelism
Uricotelism to Ureotelism
Ureotelism to Urecotelism
The transition depicted in the graph is from ammonotelism to ureotelism. Ammonotelism refers to the excretion of ammonia as the primary nitrogenous waste, while ureotelism refers to the excretion of urea. The changing levels of enzymes involved in urea synthesis indicate the shift in the tadpole's nitrogen excretion strategy from ammonia to urea. This transition is likely due to the tadpole's increasing ability to convert ammonia into less toxic urea as it develops.Hence, the correct answer is option 2
