Hey Naomi
The correct answer is: Red blood cells.
Red blood cells contains hemoglobin to carry oxygen.
In classical conditioning, the response is elicited by a stimulus that comes before it.
Classical conditioning is an instance of automatic or unconscious learning. This learning process results in a conditioned response by creating associations between an unconditioned stimulus and a neutral stimulus.
In order to expose a naturally occurring reaction to a neutral stimulus initially, we can say that classical conditioning is doing that. Salivation in response to food functioned as both the neutral signal and the naturally occurring reflex in Pavlov's well-known dog experiment. By connecting the neutral stimulus (sound) with the unconditioned stimulus, the tone's sound alone could cause salivation (food).
The first step in the classical conditioning procedure calls for a naturally occurring stimulus that will prompt a response without any further instruction. An example of a naturally occurring stimulus is salivating in reaction to the smell of food.
