lo 1.5. positive feedback

only occurs in electrical circuits: it does not apply to other types of systems.
increases the stability of a system: the result of a reaction is reduced to avoid drastic changes.
is a purely theoretical concept: it has never been observed in real - world systems.
occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly.
is a type of negative feedback: the output is reduced to maintain stability.
only occurs in biological systems: it does not apply to other types of processes.
is a type of feedback that is always delayed: it takes time for the system to respond to the output.
results in the opposite effect: the output is decreased to maintain stability.

Explanation:

Positive feedback amplifies a change or output in a system. It is not limited to electrical or biological systems and is not a type of negative feedback. It is not a purely theoretical concept and does not always have a delay. It increases change rather than reducing it for stability.

Answer:

occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly.
