A reason that some antibiotics harm bacteria but not humans is because humans have many more cells than bacteria. a. Trueb. False
A reason that some antibiotics harm bacteria but not humans is because the antibiotic inhibits bacterial enzymes that humans do not have. a. Trueb. False

Plasmids are circular extra-chromosomal DNA structures that often encode antibiotic resistance functions.D. Antibiotics always target the bacterial cell wall.
How does cyanobacterial ultrastructure compare to bacterial ultrastructure in general? 
The diagram above represents a typical rod-shaped bacterium. Which of the following best describes this cell?A. It is a prokaryote because it does not have a membrane surrounding its genetic material.B. It is a prokaryote because it is capable of making or providing itself with ATP.C. It is a eukaryote because it contains ribosomes.D. It is a eukaryote because it is surrounded by a cell wall.
