Cyanobacteria have been genetically modified to produce
a. oil
b. natural gas
c. isobutanol
d. none of the above

The correct answer is isobutanol.

Genetic engineering is the branch in which a little manipulation in the DNA of the organism can help in production of the desired product. The cyanobacteria belongs to the phylum of bacteria that performs photosynthesis.

The synthesis of isobutanol cab be done by genetically modified cyanobacteria as these modified cyanobacteria produce biofuels, such as isobutanol with the help of solar energy and carbon dioxide. They grow faster as compared to plants and absorb sunlight more efficiently so they can replenish more isobutanol.

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
