A  population of cockroaches was sprayed with an insecticide.  Some cockroaches survived and produced a population of cockroaches that was resistant to this spray.  What can BEST be inferred from this example?

• species will adapt no matter what the environment
• environment has no effect on the survival of an organism
• Individuals with favorable variations survive and reproduce
• Insecticides cause mutations that are passed on to the next generation

Why is it important to finish ALL of an antibiotic, even if you feel better?

• If all of the infectious bacteria are not killed, the bacteria may continue to multiply. Some of these bacteria may have a mutation that makes them resistant to the antibiotic. This could cause resistant bacteria to spread.

• If all of the antibiotic is not used, the surviving bacteria may learn how to fight off the antibiotic, causing the sickness to get even worse.

• If all of the antibiotic is not used, the bacteria may begin ingesting your skin cells, causing a new sickness to arise.

• If all of the antibiotic is not used, the surviving bacteria may cooperate with other infectious bacteria, resulting in two separate infections at the same time.
