How do bacteria develop resistance to drugs
Elenna [48]

Answer: Bacteria gain resistance to drugs because of mutations (permanent and random changes to their DNA) which means they have changed DNA coding, giving them the ability to resist the drug fighting them off. As a result, they survive and reproduce. Over time, more and more bacteria are generated as the DNA code for resistance is passed on over generations. This results in bacteria having the ability to resist drugs. This is particularly prevalent with antibiotics.

Which statements describe a situation with a displacement of zero
MA_775_DIABLO [31]

An object that starts and ends at the same point would have zero displacements.

<h3>What is displacement?</h3>

Displacement is the property of a body or an object to be moved from one place to another.

Thus a body that moves or is moved from point A to point B has been displaced.

A body with zero displacements either did not move at all or finished at the same point it started.

For example, a body that moves from point A to B, and then back to A will have zero displacements.
