Lu has 13 apples. He tries to put them into 2 equal piles. One pile is bigger. How many apples does the big pile have?

7 apples

Step-by-step explanation:

You can divide the apples by 2, but you will have a decimal. The closest you can get it without having a decimal is 7 in one pile, and 6 in the other. The pile with 7 apples is bigger.

The big pile has 7 apples because 13÷2 will leave you with a remainder so if you split 13 apples, 1 apple would be left, so then you add it to one of the piles to get 7 in one pile and 6 in the other.

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.
