Have you ever wondered how some animals are able to glow? Light is generally associated with the sun or with electricity, yet these creatures use neither of these to produce light. See how bright you are about bioluminescence by taking this quiz.
What is bioluminescence?
Animals that can only survive in natural light.
Animals that make their own light.
The study of animals that glow.
What is the process of incandescence?
Light produced by heat.
Light produced by a chemical reaction
Light produced by friction.
How do animals create light?
Why is luminescence known as cold light?
because it generates heat
because it doesn't require heat
because it is used in cold places
Why is it difficult for scientists to study bioluminescence in creatures?
because animals stop glowing when captured
because animals only glow in the sea
because bioluminescent animals are hard to find
When is light produced?
when an electron moves up an atomic orbit
when an electron moves down an atomic orbit
when two electrons collide
Where do most bioluminescent creatures exist?
in the ocean
in the sky
How many zones of the ocean are there, according to amounts of light that reach it?
In which ocean zone are most bioluminescent sea creatures found?
Why is the sea a blue-green color?
because blue and green have longer wavelengths
because the ocean absorbs these colors
because the ocean does not absorb these colors
What color light do most bioluminescent animals produce?
What is the milky sea phenomenon?
when bioluminescent animals produce milky waste from their light
when bioluminescent animals glow simultaneously creating a glow in the sea
when bioluminescent creatures come to the surface of the ocean during a storm
Why do animals use bioluminescence?
both of the above
How do animals use their light as camouflage?
They blend in with the light above.
They blend in with the ocean floor.
They blend in with other creatures.
What triggers the reaction that creates light in an animal?
a digestive trigger
a neurological trigger
a lymph trigger
The terms luciferin and luciferase come from the Latin word lucifer. What does lucifer mean?
Some creatures produce light using light-producing bacteria. On which part of the animal do these bacteria live?
in a light organ
in the eyes
on the tail
How do animals turn on and off the light from the bacteria?
They release the bacteria from the light organ.
They cover the bacteria.
They poison the bacteria.
What happens to an organism's light when it uses a fluorescent substance?
Its light becomes brighter.
Its light dims.
Its light changes color.
Scientist have been using bioluminescent creatures to research which diseases?
