4. Scientists today can synthesize new genes in the laboratory and insert them into living organisms where they are translated into proteins that change the nature of those organisms. What do these scientists know about the structure of genes that allows them to predict the proteins that the engineered organisms will produce?

the answer is d p: cell, q: organ, r: organ system, s: tissue

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
