An organism reacts to changes in its environment. this is called Behavior
If he's who I think he is:
A genius! :)
I might be thinking of someone else though!
The symbiotic relationship would be commensalism. It’s when one organism benefits and the other organism neither benefits nor is harmed.
This question had choices. These are the missing choices.
A) Scientists made careful observations of behavioral patterns.
B) The DNA mutation rates for both species was calculated and compared.
C) Scientists made a detailed analysis of the fossilized bones of each species.
D) The enzyme activity of each species was studied to determine similarities in metabolism.
My answer:
C) Scientists made a detailed analysis of the fossilized bones of each species.
This determination is the only feasible thing to do since dinosaurs are long dead and choices A, B, and D requires the subjects to be alive.
