cyanobacteria have been engineered to produce isobutanol directly. what advantage does this have over other alternative biofuels?\na. it is an inherently renewable fuel source.\nb. multiple processing steps can be avoided.\nc. they produce chemical energy through photosynthesis.\nd. they make a biofuel alternative to gasoline.

Answer

Brief Explanations:

The key here is that cyanobacteria can produce isobutanol directly. Other bio - fuels often require multiple processing steps to convert raw materials into the final fuel product. Since cyanobacteria produce isobutanol directly, multiple processing steps can be avoided. Option a is a general property of bio - fuels, not a unique advantage of this method. Option c is a general property of cyanobacteria and not a specific advantage for isobutanol production. Option d just states it's a bio - fuel alternative to gasoline, not a unique advantage over other bio - fuels.

Answer:

B. Multiple processing steps can be avoided.
