The population change between 1980 and 2010 would be 166 people per square mile
<h3>Population density</h3>
The change in the population density between 1980 and 2010 can be determined by taking the difference between the population density of the two years.
Population density in 1980 = 1077 per square mile
Population density in 2010 = 1193 per square mile
Change in population density = 1193 - 1077
= 166 people per square mile

I know that this is probably way to late but the answer is B
Answer:
<em>The correct option is C) the species contained large amounts of genetic variation.</em>
Explanation:
Genetic variations allow more diversity to occur in a population of species. The genetic variations among species of a population tend to make the population more stronger. The genetic variations allowed the wild plant <em>Brassica oleracea</em> to separate into many varieties such as cabbage, Brussels sprouts, kohlrabi, kale, broccoli and cauliflower.
Artificial selection is the method through which organisms with favourable characteristics are bred together so that offsprings with better characteristics can be produced.
