Any ideas?

one of the species where it is easy to see adaptations is breeds of dogs, largely because humans have shaped the traits of their genetics. choose a breed of dog and explain to the class how it has adapted to serve man in a particular way.

I'll choose Golden Retrievers:

These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.

Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.

Hope it helped,

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.
