Give written answer with explanation and conclusion
Antibiotics that target the bacterial ribosome have less side effects on humans because:
(a) bacterial ribosomes are larger
(b) bacterial ribosomes make proteins that humans do not make
(c) bacterial ribosomes contain only sugar residues
(d) bacterial ribosomes are smaller

a.Endocytosis
b.Endosymbiosis
c.Autophagy
d.Exocytosis
Compare and contrast the Gram-positive and Gram-negative bacterial cell walls. Discuss the cell wall components that make the Gram-positive and Gram-negative bacterial cell wall different from each other. Explain why you think one cell wall is stronger than the other.
