Determine whether the triangle is a right triangle 12, 10, 11...​

no it's not right angled

Step-by-step explanation:

thats because the left hand side is not equal to the right hand side

You were on the right track: basically if a²+b²=c² is true , it's a right triangle...

a²+b²=c²

11²+10²=12²?

121+100=144?

221=144?

221≠144

Since they're not equal, the triangle isn't a right triangle.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
