Although Chargaff used DNA from both prokaryotic and eukaryotic organisms, there are several differences between the DNA in prokaryotes (like the bacteria Escherichia coli) and eukaryotes (like
turtles). Which of the following accurately describes one of these differences?
A. Prokaryotic cells only contain adenine and thymine, but no guanine and cytosine.
B. Prokaryotic cells contain circular DNA molecules called plasmids.
C. Eukaryotic cells have less DNA, and therefore fewer genes than prokaryotic cells.
D. Eukaryotic DNA is double stranded and prokaryotic DNA is single stranded.

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.
