The Animal Kingdom is primarily defined by multicellularity, which distinguishes animals from unicellular organisms.

The exoskeleton in arthropods provides support and protection, allowing them to maintain their shape and protect against predators.

The primary function of the respiratory system is gas exchange, allowing oxygen to enter the body and carbon dioxide to be expelled.

Most animals exhibit bilateral symmetry, which allows for a distinct head and tail end.

Vertebrates are the group of animals that possess a backbone, distinguishing them from invertebrates.

Frogs are a classic example of amphibians, which typically undergo metamorphosis from a larval stage to an adult form.

Reptiles are characterized by their scaly skin, which helps prevent water loss and provides protection.

Budding is a form of asexual reproduction where a new organism develops from an outgrowth of the parent.

Mammals are characterized by live births and mammary glands; while some lay eggs, it is not a defining characteristic of all mammals.
