Bronchial Tubes - Large tubes that carry air into smaller branches of the lungs after the air has passed through the mouth, nasal passages, and windpipe.⏎
Antibiotic Resistance - The process through which pathogenic microorganisms, by way of genetic mutation, develop the ability to withstand exposure to the drugs that had once been successful in eradicating them.⏎
Antibodies - A class of drugs used to kill or inhibit the growth of disease-causing microorganisms. Typically antibiotics are used to treat infections caused by bacteria, but in some cases they are also used against other microorganisms, such as fungi and protozoa.⏎
Chromosome - An organized structure of DNA and proteins within the nucleus of a cell that contains many genes.⏎
Adaptive Mutation - A mechanism through which certain cells can increase the rate in which genetic mutations occur, often in response to stress. This mechanism may help explain how bacteria develop resistance to certain antibiotics.⏎
