Solve the following system of equations
x-2y = 5
2x - 4y = 10

infinitely many solutions
no solutions
(0,0)
(5,10)

Infinitely many solutions

Step-by-step explanation:

2(x-2y)=2(5)

2x-4y=10

-2x+4y-10

Thus,

0=0.

so, infinitely many solutions.

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.
