Lesson 9 Check In

Front

What is the process by which bacteria reproduce?

Back

Bacteria reproduce by making identical copies of themselves, resulting in offspring that have the same traits as their parents.

Front

What is MRSA?

Back

MRSA stands for Methicillin-Resistant Staphylococcus Aureus, a type of bacteria that is resistant to many antibiotics.

Front

What does it mean for bacteria to have variation?

Back

Variation in bacteria refers to differences in traits among bacterial populations, which can arise from mutations or genetic exchange.

Front

What is the significance of antibiotic resistance in bacteria?

Back

Antibiotic resistance allows bacteria to survive and multiply in the presence of antibiotics, making infections harder to treat.

Front

How can bacteria acquire new traits?

Back

Bacteria can acquire new traits through processes such as mutation, transformation, transduction, and conjugation.

Front

What is the difference between resistant and nonresistant bacteria?

Back

Resistant bacteria can survive exposure to antibiotics, while nonresistant bacteria are killed by them.

Front

What is the role of plasmids in bacteria?

Back

Plasmids are small, circular DNA molecules that can carry genes, including those for antibiotic resistance, and can be transferred between bacteria.

Front

What is the importance of studying bacterial infections?

Back

Studying bacterial infections helps in understanding how to prevent, diagnose, and treat diseases caused by bacteria.

Front

What is a bacterial colony?

Back

A bacterial colony is a visible cluster of bacteria growing on a solid medium, originating from a single bacterium.

Front

What is the difference between a pathogen and a non-pathogen?

Back

Pathogens are microorganisms that cause disease, while non-pathogens do not cause disease and can even be beneficial.
