The clustered, regularly interspaced short palindromic repeats (crispr) system in bacterial cells has been called the "immune" system of bacteria. crispr protect bacteria from a repeat infection from the same phage because bacterial cells

By integrating the phase fragment in their own chromosome

Explanation:

The clustered regularly inter spaced short palindromic repeats are known as CRISP, found in the bacterial cell which acts as the immune system in case of bacterial cell.

These bacteria protect themselves from same infection twice by integrating the fragments from the phage DNA in their chromosomes and in case of further infection they recognize the fragment and prevents the cell from infection.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
