How do camels survive in the heat of the Sahara Desert?

• By drinking a lot of water

• By having thick fur

• By storing fat in their humps

• By living underground

What is the nickname of the tardigrade?

• Space bear

What is the temperature range that tardigrades can survive?

• -100°C to 100°C

• -200°C to 151°C

• -50°C to 50°C

• -300°C to 200°C

What can the survival of tardigrades in outer space suggest about the potential for life beyond Earth?

• Life can only exist on Earth

• Life forms must have similar adaptations to tardigrades to survive in space

• The conditions in space are not as harsh as previously thought

• Life might exist in extreme environments on other planets or moons

What are extremophiles?

• Organisms that live in moderate environments

• Organisms that live in extreme environments

• Organisms that live in water

• Organisms that live in forests

Where does Strain 121 live?

• In the Sahara Desert

• In the Arctic

• On a volcanic vent at the bottom of the Pacific Ocean

• In the Amazon Rainforest

What is the main interest of scientists studying extremophiles?

• To find new medicines

• To understand how life might exist on other planets

• To create new technologies

• To improve agriculture

Where do methanogens thrive?

• Under 18 meters of Antarctic ice

• In the Sahara Desert

What can the study of organisms like tardigrades and extremophiles teach us about the resilience of life?

• Life is fragile and easily destroyed

• Life can adapt to and survive in a wide range of extreme conditions

• Only large organisms are resilient

• Resilience is not an important factor in the survival of life
