Answer:
Spontaneous recovery
Explanation:
An individual takes a sweat inducing injection in a dark room. This act of sweating is an Unconditional Response to the Unconditioned Stimuli which is the Injection.
After some time, whenever the individual is in a dark room, he begins to sweat. This is now a Conditioned Response (Sweating) to a Conditioned Stimuli(The Dark room).
If after some time, this conditional response lessons and goes away, it is referred to as Extinction.
However, after a period of absence, if the Conditioned Response returns, it is referred to as Spontaneous Recovery.
Cyanobacteria, also known as "blue-green algae", are the unicellular organisms which are able to produce oxygen.
Approximately 540 years ago, the atmosphere was very poor on oxygen. Cyanobacteria are thought to be responsible for the oxidization of the atmosphere back then, in an event known as <em>"The Great Oxygenation Event"</em>. As a result, Earth's life forms suffered drastic changes in their composition, as they evolved from being <em>anaerobic</em> to becoming organisms <em>highly dependant</em> on oxygen. The oxygenation of the atmosphere would eventually provide the adequate environment in order for the <em>Cambrian Explosion</em>, or the first diversification of living organisms, to happen.
