C ribosomes is ur answer
mark me brainlist plz :)
Reproduce and soon take over the island with the ancient power if iguanas, jk jk
though they will reproduce it will depend on the food source and if there is a food source since they are introduced to a new environment they most likely won't have any predators and can eat and move freely as much as they want to.
I hope this helps
