1) Is there a link between the amount of cigarette smoking in countries and death rates from coronary heart disease (CHD)? Below is computer output from a regression analysis of this

relationship for 14 randomly-selected countries from around the world. The explanatory variable

is annual consumption of cigarettes per person and the response variable is annual deaths from

coronary heart disease per 100,000 people.

I uploaded the answer to a file hosting. Here's link:

i believe the correct answer is b.

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.
