Mutation
Which of the following is true about antibiotic-resistant bacteria?
Because there are antibiotics in the environment, they become immune
They learn to fight the antibiotic
Antibiotic resistance is caused by mutations
Are those dancing dogs?
Which of the following is true about antibiotic-resistant bacteria?
Bacteria with antibiotic resistance are more likely to survive and reproduce
Over time, the entire population will become antibiotic resistant
Bacteria don't mutate as a result of exposure to the antibiotic
All of these
Mutations are important because they bring about
death of the organism in which they develop
genetic variation needed for a population to evolve
benefits for the individual, not for the population
Below is a graph of an infection with 1,000,000 bacteria. The patient was given multiple doses of an antibiotic to kill the bacteria. Each dose was 99.9% effective and doses were given every 4 hours for 24 hours. Between each dose, the remaining bacteria divided every 20 minutes.
Refer to the graph above. What type of growth does the bacteria display after each antibiotic dose is given?
exponential growth
logistical growth
linear growth
spiritual growth
RANDO TRIVIA: What letter is the only letter that does not appear in the name of a US state?
Y
X
Z

A population of insects with yellow and green variations lives in the trees in a rainforest. A predator of the insect uses its eyesight to find its food. What do you expect to happen to the green and the yellow variations of the insect over time?
The number of green insects will increase and the number of yellow insects will decrease.
The number of yellow insects will increase and the number of green insects will decrease.
Both variations will remain constant over time.
Both variations will increase over time.

Variations in the bacteria allowed some organisms to be less affected by the antibiotic?
