Two lines, a and b, are represented by the equations given below:

line a: x + y = 6
line b: x + y = 4

which statement is true about the solution to the set of equations?

1) there are infinitely many solutions.
2) there is no solution.
3) it is (6, 4).
4) it is (4, 6).

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.  

answer: ♡♡♡♡♡♡♡♡♡♡

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
