The Evolution of Resistance

Question 1

How does the evolution of antibiotic resistance begin for bacteria?

Answer 1

genetic variation wherein some are resistant to an antibiotic

Question 2

How can bacteria develop the trait of being resistant to an antibiotic?

Answer 2

genetic mutations that occur quickly

Question 3

When an antibiotic is introduced to the environment, what happens?

Answer 3

the antibiotic acts as a selective pressure and selects for those resistant to the antibiotic, killing the rest

Question 4

Bacteria resistant to the antibiotic survives after the antibiotic is introduced. What happens?

Answer 4

they reproduce and produce a generation with that same resistant gene because the resistant bacteria have better fitness

Question 5

If a farmer is using a pesticide over many years, what would happen?

Answer 5

all of the insects would be resistant to that specific pesticide

Question 6

What would a farmer have to do in order to protect their crops?

Answer 6

rotate the type of pesticide, or use it less often

Question 7

How does the evolution of pesticide resistance begin for insects?

Answer 7

genetic variation wherein some insects are resistant to a pesticide

Question 8

How can insects develop the trait of being resistant to a pesticide?

Answer 8

genetic mutations wherein some are resistant to a pesticide

Question 9

When a pesticide is introduced to the environment, what happens?

Answer 9

the pesticide acts as a selective pressure and selects for insects resistant to the pesticide, killing the rest

Question 10

Insects resistant to the pesticide survive after the pesticide is introduced. What happens?

Answer 10

they reproduce and produce a generation with that same resistant gene because the resistant insects have better fitness
