Natural Cellular
HELP! I am really having a hard time with this question! it is very difficult for me!?
Scientist are concerned that the widespread use of antibacterial soaps and detergents will lead to the development of resistant bacterial strains. Which process be responsible for this development?
a. cloning
b. natural selection
c. cellular respiration
d. genetic engineering
it would be B. - natural selection.
when bacteria comes into contact with antibacterial soap (when we wash our hands with it), there are most likely going to be bacteria that are killed, and some that will not be killed. usually, most bacteria is killed, and a small portion of them survive. obviously, if they survive, these bacteria can live long enough to reproduce and create offspring that, like them, can survive the antibacterial soap. some of these offspring will be killed, and some will survive, and then they will live to reproduce. this keeps repeating itself until all or most of the bacteria will be resistant to antibacterial soap.
i hope this makes sense!
