Animals similar to salamanders first appeared on earth during the period a) devonian b) mississippian c) pennsylvanian d) permian

The answer is d) Permian

Explanation:

The Diplocaulus was an animal similar to the salamander that existed during the Permian Period.

Diplocaulus belongs to the group of lepospondyls. Not to be confused with dinosaurs, since this animal lived long before these, this ancient amphibian disappeared when the dinosaurs began to inhabit the earth. This animal inhabited the earth during the Paleozoic Era, in the subdivision called as Permian.

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.
