True
cartilage or bone
Amphibians are vertebrates, meaning they have a backbone. The skeletal system is mostly made up of bone, but also contains some smaller portions of cartilage. Not all vertebrates have bone skeletons, Chondrichthyes (sharks, rays etc.) have skeletons made up entirely of cartilage. Amphibians however do not.
yes; endoskeleton of vertebrates may be either bone or cartilage
No. Amphibians have bones, including a backbone, as they are vertebrates.
Invertebrates are animals without backbones, such as worms, shellfish, and in almost all vertebrates, bone gives the skeleton its strength.
The skeletons of amphibians, like those of other vertebrates, are composed of bone and cartilage. They share a common structural organization, with a skull, vertebral column, and limb bones. Additionally, amphibian skeletons serve similar functions, providing support, protection, and facilitating movement. Despite some variations in specific adaptations, the fundamental similarities in skeletal structure reflect shared evolutionary ancestry among vertebrates.
The answer is False. The tendon Connects muscle to the bone.
False, bone contains capillaries.

True
Yes, clown fish are vertebrates. They belong to the class of vertebrates called Actinopterygii, which includes all ray-finned fish with skeletons made of bone. Clown fish have a bony spinal column and internal skeleton, making them vertebrates.
A chickadee is an American non-migratory bird, and does have a spine.
