Why do antibiotics destroy bacterial cells but have no effect on viruses?
Viruses are made up of organic molecules that are too small to be targeted by antibiotics.
Viruses are not alive and do not carry out the life functions that are stopped by antibiotics
Viruses do not possess the protein coat that is targeted by all antibiotics
Where do adaptations come from?
The individual organism decides to adapt
Mutations that give an organism an advantage in its environment
Genetic recombination during sexual reproduction
Both mutations and genetic recombination are sources of adaptation
Using the 4 principles of natural selection - Variation, Overproduction of Offspring, Competition, Survival/Reproduction - Describe and draw how bacteria become antibiotic resistant.
Using the 4 principles of Natural Selection, describe how mimicry evolved in the sound producing moths or the scarlet kingsnake.
Use a model to illustrate and describe how disease can be spread and cause illness. Include mode of transmission, population density, type of pathogen, and virulence in your model.
People are increasing the rate at which bacteria populations are acquiring antibiotic resistance by:
taking antibiotics only when they need them
putting antibiotics into our food and environment
not sharing antibiotics with others
What can we do to reduce the rate of development of antibiotic resistant strains of bacteria
Always finish a course of antibiotics
Only take antibiotics when they are really needed
Take antibiotics whenever it is possible
Reduce the amount of antibiotics given to animals in the farming industry
A population of bacteria is treated with an antibiotic; however, a few remaining bacteria survive. How did this antibiotic resistance occur?
The bacteria acquired new traits that enabled them to survive the treatment.
The antibiotic was not strong enough.
The wrong antibiotic was used to treat the infection.
The bacteria possessed mutations that made them naturally resistant to the medicine.
Evolution by natural selection says that change occurs in:
Individuals
Species
Populations
Communities
Natural selection is best described as the survival of:
The largest and strongest organisms
Organisms that best outcompete others for territory
The fastest organisms in a habitat
Organisms that possess traits that are best suited to their environment
