Evidnce For Evolution Flashcards
What does bacteria develop
It sometimes develops random mutations in their DNA
What’s good about the random mutations
They create new alleles which change the characteristics bacteria have
How can antibiotics help bacterium
It makes it become less affected by a particular antibiotic ( stops to prevent more reproducing )
What’s an advantage for bacterium
It had the ability to resist as the resistant bacteria has a better chance to survive so it lives longer and reproduces
After the reproducing, what happens to the allele. And what does this lead to
It passes on lots of other offspring ( just like natural selection ) and then
How is antibiotic resistance is that bidnce got evolution
The bacteria is better adapted to the enviroment. This in which antibiotics ( a selection pressure ) are present
