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.

the boundarys like convergent divergent and transform it causes subduction

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
