Multiple Choice

• mutation

• gene therapy

• natural selection

• selective breeding

Multiple Choice

Weakened microbes that stimulate the immune system to produce antibodies used to fight future invasions by the same microbe. Example: chicken pox, measles, small pox

• Vaccine

• Disease

• Immunity

Multiple Choice

A protein, produced by the immune system that either attacks invading pathogens or marks them for killing.

• Antibodies

• Microbe

• AIDS

• Allergy

Multiple Choice

Which is an example of passive immunity?

• people being vaccinated against disease
• people taking vitamins to boost their immune response
• people receiving antibodies from their mothers before birth

Multiple Choice

A medicine that kills bacteria

• antiviral
• antibiotic
• anti-fungal
• antiacid

Multiple Choice

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

Multiple Choice

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.
