Infection
What is it called when one organism invades another?
Infection
What is Staphylococcus?
A common type of bacteria infection.
What is adaptation?
change by which an organism becomes better suited to its environment.
What is offspring?
New organisms created by reproduction.
What is a Petri dish used for?
To grow bacteria and other microorganisms
What kind of microorganisms can cause infections in humans?
Bacteria
What is Stenotrophomonas known for?
t is a less common type of bacteria infection that is very dangerous and hard to treat.
What does it mean for a trait to be heritable?
It is passed down from one generation to another.
How does a new generation of bacteria form?
Bacteria divide into two identical copies of themselves.
What is agar?
The nutrient gel in a Petri dish that bacteria can grow on.
What medicine is used to kill bacteria?
Antibiotic
What does "pan-resistant" bacteria mean?
Bacteria that are not able to be treated with any antibiotics.
Define natural selection.
The process where organisms with advantageous traits survive and pass those traits to offspring.
What is the process called when a species completely disappears?
Extinction
What do simulations help us understand?
hey help us see how bacteria populations change over time.
What is a "dose" in relation to antibiotics?
One measurement of a substance taken at a time
Name a type of Staphylococcus that is resistant to Methicillin.
Methicillin-resistant Staphylococcus aureus (MRSA).
How does mutation contribute to evolution?
Mutations create changes in DNA that can lead to new traits.
How are inherited traits passed down?
Through DNA from parent to offspring
Why do scientists use simulations in experiments?
To model and predict changes in populations or systems.
What happens to bacteria that are resistant to antibiotics?
They are not killed by that antibiotic.
What is the main difference between bacteria and viruses?
Bacteria are living microorganisms; viruses are not.
What is the process of evolution?
The change in inherited characteristics of a species over generations.
What is the significance of generations in evolution
Generations allow for the passing down of traits and adaptation over time.
How can bacteria populations change over time?
Through reproduction, mutation, and natural selection.
