Answer:
Amoxicillin inhibits an enzyme required to build cell walls in bacteria.
Since humans have cell membranes, they are unaffected by amoxicillin.
Explanation:
Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.
Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.
Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees, in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.
Hope this helps!

Membrane-bound immunoglobulin on the B-cell surface serves as the cell's ... of antibody molecules allows each antibody to bind a different specific antigen, .
The cell membrane is the structure that separates a cell and its environment. The cell membrane is an important part of the cell that provides an essential function to the cell protecting the cell and determining what is passed in and out of the cell.
