According to the opponent-process theory, cells that are stimulated by exposure to light are inhibited by exposure to light. yellow; blue red; blue blue; green yellow; green blue; red

YELLOW; BLUE

Explanation:

OPPONENT PROCESS THEORY OF COLOR

This theory suggests that we are able to perceive colour through 3 receptor complexes who oppose each other being the red-green complex, the blue-yellow complex, and the black-white complex.

According to this theory, there are cells that can only detect the presence of one color in the complex at a time because the two colors oppose one another. For example, humans cannot see a greenish red because the opponent cells can only detect one at a time.

Interesting theory but let me not digress. The blue-yellow complex oppose each other and so the first option is correct.

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.
