The scale on a map shows 5 centimeters =2kilometers what number of centimeters on the map represents an actual distance of 5 kilometers

12.5 cm.

Explanation:

For every 2 kilo meters, there are 5 centimeters. 5 kilo meters is 2.5 times more than 2 kilo Meters. So you multiply 5 centimeters by 2.5 and that is the answer.

8 km.

Explanation:

If you divide 5 cm by 2, you get 2.5. So divide 2 km by 2.5 and that is how you get .8.

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.
