Taxonomy used to have two groups of vertebrates and invertebrates. But invertebrates are far more diverse when it comes to the phylogenetic tree. Vertebrates all share same characteristic which is a back bone made of vertebrae, but invertebrates don’t share a common anatomical structure that all have; they are radically different in structure so they can’t be grouped in a single group. You have Arthropoda, which all have jointed limbs and segmented bodies and molt their cuticles. There’s Cnidaria, which most have tentacles and nematocysts and are radially symmetrical. And Mollusca, which have a muscular foot and a part of their body called a mantle. All these groups are invertebrates, but there’s nothing they share in common WITHOUT referring to the fact that they don’t have vertebrae. So basically that’s just an example why they can’t be grouped into one category; they all have different characteristics and are placed in different areas of the animal kingdom’s phylogenetic tree. Hope this helps
Answer:
The correct answer will be- compound fracture.
Explanation:
Bone fracture is the breaking of bone due to accidents, sports injuries, falls, osteoporosis and low bone density.
The fracture should be of various types depending on the degree but a type of fracture where a fractured bone protrudes out from the skin is known as an open fracture or compound fracture. The open fracture can also be a case of a medical emergency as it could lead to osteomyelitis, a type of bone infection.
Thus, the compound fracture is the correct answer.
