The Lab in Space: Life Detection Experiments Quiz

How do you ask the universe if it's alive? From testing for metabolism to looking for DNA-like structures, scientists must carefully choose what to measure. This life detection experiments quiz explores the logic and...

Questions: 20 | Attempts: 11 | Last updated: Feb 20, 2026

Sample Question 1
When designing life detection experiments based on metabolism, what is the significance of "Labeled Release" using Carbon-14?

To measure the mass of the planet

To detect if microbes ingest nutrients and release radioactive waste gas

To find the age of the soil

To measure surface radiation

To identify the color of the microbes

Sample Question 2
In the context of how scientists search for life, a "False Positive" occurs when an abiotic chemical reaction mimics a biological process.

True

False

Sample Question 3
Why is "Homochirality" (the use of only one "hand" of a molecule) a key target for detecting microbes planets?

It makes the microbes move faster

Non-living chemistry produces 50/50 mixes, while life prefers one specific shape

It allows life to survive in a vacuum

It is only found on Mars

It prevents the star from killing the life
