Answer 1

The correct answer is a reflex. Sara allows her dog, Isabel, to run freely at a local park. When Isabel is chased by several other dogs, Sara notices that Isabel's hair rises up along her spine.

Step-by-step explanation:

The correct answer is d. a reflex.

Sara allows her dog, Isabel, to run freely at a local park. When Isabel is chased by several other dogs, Sara notices that Isabel's hair rises up along her spine. This response is known as piloerection, which is a reflexive response triggered by fear or agitation.

Reflexes are unlearned, involuntary reactions to specific stimuli in the environment. In this case, the stimulus of being chased by other dogs causes Isabel's hair to rise along her spine as a reflexive defensive mechanism.
