Question

Quizplus · Accepted Answer

Innate defenses are non-specific defense mechanisms that some organisms have to protect them from predators. These can include physical barriers (such as shells or spines), chemical deterrents (such as toxins), or behavioral adaptations (such as hiding or burrowing). Cellular immunity, humoral immunity, adaptive immunity, and acquired defenses are all specific defense mechanisms that are typically associated with the immune systems of vertebrates.
