If an organism is exposed to a small amount of a poison it may not die and instead, gradual exposure to the poison can lead to the organism building up a resistance to it. This resistance can sometimes get passed on to the offspring of the organism, as it is a useful evolutionary adaptation, consequently the offspring also become resistant to the poison.

What is important about staph?
Staph, or staphylococcus is a type of bacteria that is becoming increasingly resistant to antibiotics. The most resistant of these are MRSA and can be very dangerous.
The bacteria that has been most effective at becoming resistant to antibiotics is?
Clostridium difficile.
Does bacteria exhibit genetic diversity within bacterial species?
Yes. This is why bacteria are becoming resistant to antibiotics.
What are the advantages and disadvantages of tuberculosis?
advantages: none disadvantages: it can kill you, it is rapidly becoming resistant to antibiotic treatment
How does binary fission result in bacteria becoming resistant to antibiotics?
the genes of the bacteria have to be replicated, allowing for the chance of genetic mutation.
Which material is best for cut resistant gloves leather or something else?
Cut resistant gloves are becoming more of a necessity in the work field. The best material for these gloves is leather. Another great option is Kevlar.
Why is the overuse of antibiotics a problem?
It exposes too many organisms to antibiotics, and exposing them too frequently. This results in the opportunity for the organisms to become resistant to the antibiotics. Antibiotic resistant bacteria are becoming a more and more serious public health threat.
How have viruses changed over time?
By adapting to the current environment, growing resistant to various threats and becoming more lethal.
Will farming ever become popular again?
When all the farm produce is infected with chemicals / pesticides / fertilizers etc; and we have nothing pure/natural to eat; maybe that day onward it will start becoming.
What is an example of genes becoming more common in a population?
One example of a gene becoming more common in a population is antibiotic resistance in bacteria. When the antibiotics kill the bacteria some have a mutation that makes them resistant. These bacteria then reproduce and over time the species genetic code changes so that they are antibiotic resistant. This is the reason new vaccines are constantly released. The same basic principle works in pesticide resistance of rats.
What impact did penicillin have on medicine?
It helps to kill bacteria. Therfore, it can treat many diseases. Although in modern time, bacteria are becoming resistant to antibiotics and penicillin is losing its effects.
How is bacteria becoming immune to medications?
Bacteria are one of the simplest organisms, a little evolved from viruses and just like viruses, they can also mutate and become resistant to human medicines.
