Can someone help me please!:(

Step-by-step explanation:

2(5y + 3) - 4(7y + 1) = - 88

Multiply the terms in the bracket

That's

10y + 6 - 28y - 4 = - 88

- 18y + 2 = - 88

Subtract 2 from both sides

That's

- 18y + 2 - 2 = - 88 - 2

- 18y = - 90

Divide both sides by - 18

We have the final answer as

Hope this helps you

step-by-step explanation:

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.
