Bone fractures in which the bone protrudes through the skin are called
(a) greenstick fractures.
(b) compound fractures
(c) simple fractures.
(d) stress fractures.

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.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
