A scientist discovers a soil bacterium that produces an chemical with antibacterial properties. After isolating and purifying the chemical compound, she completes a rigorous antimicrobial susceptibility testing experiment and discovers it only is effective against Staphylococcus aureus and no other bacterial species. The scientist then chemically alters the compound in her laboratory. When she tests the antimicrobial effectiveness of this new, slightly modified compound, she finds that this new compound is now also effective against many other gram-positive bacterial species. In one sentence, describe the INITIAL chemical (the one she intially discovered) in terms its of spectrum of activity. Explain your rationale for full credit. In another sentence, describe the MODIFIED chemical in terms of its spectrum of activity. Explain your rationale for full credit. In another one to two sentences, categorize the INITIAL and MODIFIED drugs as being natural, synthetic, or semisynthetic. Explain your rationale for full credit.
