Unit 2 Pre-Assessment: Human vs Bacteria

Front

What is the microbiome?

Back

The microbiome refers to the diverse community of microorganisms, including bacteria, fungi, and viruses, that inhabit various environments in the body and play a critical role in health.

Front

What is the importance of studying the microbiome?

Back

Studying the microbiome is important because it helps us understand its diversity and critical role in maintaining health, influencing digestion, immunity, and even mental health.

Front

Define cooperative behaviors in bacteria.

Back

Cooperative behaviors are actions that benefit a group of organisms, such as bacteria working together to survive, share resources, or enhance their survival.

Front

What is the role of a host in a viral infection?

Back

The role of a host in a viral infection is to provide a place for the virus to reproduce and thrive, often at the expense of the host's health.

Front

What is a symbiotic relationship?

Back

A symbiotic relationship is a close, long-term interaction between two different species, which can be beneficial, neutral, or harmful to one or both parties.

Front

What does antibiotic resistance mean?

Back

Antibiotic resistance occurs when bacteria evolve and develop the ability to survive exposure to antibiotics that would normally kill them or inhibit their growth.

Front

How can bacteria communicate with each other?

Back

Bacteria can communicate with each other through a process called quorum sensing, where they release and detect signaling molecules to coordinate their behavior.

Front

What is the difference between pathogenic and non-pathogenic bacteria?

Back

Pathogenic bacteria are harmful and can cause disease, while non-pathogenic bacteria are generally harmless and can even be beneficial to human health.

Front

What is the significance of the number of antibiotics a bacteria is resistant to?

Back

The number of antibiotics a bacteria is resistant to is significant because it indicates the potential difficulty in treating infections caused by that bacteria.

Front

What is an example of a symbiotic relationship?

Back

An example of a symbiotic relationship is the interaction between gut bacteria and humans, where bacteria help digest food and produce vitamins in exchange for nutrients.
