Which of the following is a behavioral adaptation? a: an arctic hare has a white coat in the winter b: a fawn remains very still to avoid being seen c: a male cardinal has a very bright red feathers d: a hummingbird has a long thin bill.

I’d say B is the best choice

All the other options aren’t a behavioral adaptation because they were all born with those features. A fawn wasn’t born with the knowledge to be still to avoid predators.

Hope this helps you

the answer is b: a lockout

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
