A scientist cuts the gene that codes for insulin production from a strand of human DNA. He then inserts this gene into the plasmid of a bacterium, which causes the bacterium to produce insulin. The scientist harvests the insulin produced by the bacterium and packages it to be provided to diabetics. What type of biotechnology did the scientist in this scenario use to produce insulin? A. genetic engineering
В. DNA fingerprinting
C. reproductive cloning
D. selective breeding

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .

idk what happened..you tell
