It was noted in the text that the genetic “code” is best thought of as written in

The answer is erasable pencil. In the text, the genetic code as sketched in erasable pencil rather than indelible ink. The reason behind this is that gene expression can be changed, starting prenatally all the way through the lifespan, and sometimes in lasting ways by environmental factors. Genes do not conclude anything. Rather, genes and environment work together and co-act to persuade gene expression and in-turn, development and behavior throughout the life span.

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 !
