The sum of two numbers is 49 the smaller number is 21 less than the larger number what are the numbers

x=35,14

Step-by-step explanation:

x+(x-21) =49, combine like-terms and add 21

2x=70

x=35

Now, input 35 for x-21.

35-21=14

35+14=49, which is true and 14 is 21 less than 35.

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.
