When people look at a photograph of an adult-child pair and are told that the two individuals are parent and child, the people tend to say the pair looks more alike than people who are told the pair is unrelated. this is most likely due to

hereditary or their genes

hope this helped you hon

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 !
