Genes that code for a specific protein can be inserted into bacterial plasmids, and then the plasmids are used to transform cells. many useful human proteins are now synthesize by these transgenic bacteria. Uses for the synthesized proteins include human insulin used to treat diabetes and human growth hormone used to treat dwarfism. Which tenet of cell theory best serves as a basis for this type of biotechnology

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

i believe it is c: genes for body color and wing size are inherited separately from each parent.
