Heres a long answer,hope you don't mind :) A frog's forelegs, also called arms, contain humerus, radius and ulna bones similar to those of a human's. However, a frog's radius and ulna are fused together. Frogs' upper legs contain a femur, and its lower leg bones, the tibia and fibula, are fused together.
Frogs typically have four toes on their front legs and five on their back legs, with lengths varying by different species. Tree frogs who do a lot of climbing and aquatic frogs who require webbed toes for efficient swimming tend to have very long digits. Frogs that live in the mud typically have shorter toes that they utilize as shovels.
The skull of a frog contains five bones and it is connected directly to the spine without a neck vertebrae. At the terminus of the spine, a frog's vertebrae are fused together into a single bone. Due to the lack of ribs, a frog's pelvis is able to slide up and down its spine. This skeletal adaptation is thought to increase jumping ability.
3: Trees are very eco friendly and they are what help us breathe natural air. They have a impact in a pro and con way. Pro, they build more stores, homes, and things we need in those spaces. Con: They are killing our fresh air and we don’t need that. The world is already going through disasters, and we are getting animals extinct.
