I don't understand this question can you help me pls?

Step-by-step explanation:

1125*3=3375

The first diagram shows how to multiply each number separately instead of the normal way. It shows you in sections instead one line.

The question asks if you started with the first "1" in 1125, will the answer be different. The answer is no.  

since the hundred number given, when multiplied by the 3, will not result in "carrying the 1 over to the thousand place, the answer will not change.

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.
