-5.875

Step-by-step explanation:

primero se resuelve el paréntesis

1/4 =0.25

y se multiplica por el -6

0.25x-6= -1.5

luego se resuelve el otro lado

primero dividimos

5/8=0.625

y se multiplica por -7

0.625x-7= -4.375

y para finalizar se suman los dos lados

-4.375 + -1.5

= -5.875

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.
