How did one species produce so many different species (the six ecomorphs)? a. because the islands were isolated for an extended period, a lack of interbreeding between populations of the same species caused all the species to diverge. b. without competition from other species, the one species adapted to fit all of the available habitat types. c. to fill all the needed jobs in their ecosystem properly, anolis lizards diverged into exactly the amount of species necessary for their habitat. d. because the anolis lizards have such a diverse range of characteristics, they were able to produce many different species. submit for grading save and finish later?

Option A

Explanation:

There are basically two hypotheses that explains the evolution of six ectomorphs  

a)When the ectomorphs were evolving the island was in contiguous state. Due to this plate tectonic movement was high that ultimately led to the division of island into six different islands which caused these ectomorphs evolve separately due to the geographical barrier.

b)Second theory could be that all ectomorphs evolved on the same island but then with the division of island, they got separated.  

Hence, option A is correct

explanation:

they can be good for the ecosystem

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
