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.
Which of the following best describes how natural selection results in insects that are pesticide resistant?
When a pesticide is sprayed on a crop, a few insects survive. These insects happen to have a random mutation that makes them resistant to the pesticide. These insects survive and reproduce, eventually resulting in pesticide-resistant population.
When a pesticide is sprayed on a crop, the insects respond by mutating their DNA, making them resistant to the pesticide. Therefore, a pesticide resistant population evolves.
When a pesticide is sprayed on a crop, it causes mutations in the insect DNA. Some of these mutations make the insects pesticide-resistant. These insects now form a pesticide-resistant population.
When a pesticide is sprayed on a crop, it kills the insects, which allows a new species to migrate into the habitat. Some of these species are pesticide resistant, thus a new population of pesticide resistant insects appears.
Which of the following best describes how natural selection results in bacteria that are antibiotic resistant?
When you take an antibiotic when you're sick, a few bacteria survive. These bacteria happen to have a random mutation that makes them resistant to the antibiotic. These bacteria survive and reproduce, eventually resulting in an antibiotic-resistant population.
When you take an antibiotic when you're sick, the bacteria respond by mutating their DNA, making them resistant to the antibiotic. Therefore, an antibiotic-resistant population evolves.
When you take an antibiotic when you're sick, it causes mutations in the bacteria DNA. Some of these mutations make the bacteria antibiotic-resistant. These bacteria now form a bacteria-resistant population.
When you take an antibiotic when you're sick, it kills the bacteria, which allows a new species of bacteria to infect the body. Some of species are antibiotic resistant, thus a new population of antibiotic-resistant bacteria appears.
