Theodosius Dobzhansky discovered that successful species tend to have a wide variety of genes that do not appear to be useful to the species in
its present environment. What did this discovery help explain about
genetics and the changes that occur in a species over time?

A. Environments with more organisms tend to have more
successful species.

B. Species with greater genetic diversity adapt more easily to
changing environments.

C. Changing environments prevent species from adapting and
surviving.

D. Species in a stable environment are more resistant to a
changing environment.

Explanation:

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
