A biology student wanted to study the effect of fertilizer on the growth of tomato plants. He placed four of the same type of tomato plants into separate containers, each containing the same amount of soil. Each pot received a different watering solution, containing varying amounts of fertilizer. The table below shows the average height of the plants by the end of one week.

B. The amount of fertilizer

can you tell me where are the ansawer choices

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 !

in an absolute  monarchy, the  monarchrules as an autocrat, with absolutepower  over the state and government — for example, the right to rule by decree, promulgate laws, and impose punishments. the  monarch isnominally sovereign but the electorate, through their legislature, exercise political sovereignty.

i am pretty sure it is d.
