What multicellular life forms existed on earth before dinosaurs existed on earth (mark all that apply) corals some land plants early molluscs, like giant cephalopods (distant relatives of squids and octopi) ■ birds mammals fishes early arthropods, like trilobites

Some land plants and arthropods like trilobites existed before the dianosaurs existed on Earth.

Explanation:

The first reptiles are reported to have appeared during the Carboniferous period. The Dinosaurs were large reptiles that became dominant during the triassic and jurassic. By the end of cretaceous the dinosaurs became extinct.

In the given options we find that some land plants and trilobites are suitable choice because, firstly, the fossil plants are recorded during carboniferous period and some of those species became extinct before the appearance of dinosaurs. Secondly, trilobites became extinct by the end of permian period.

Rest of the options like birds, mammals, etc came into existence before dinosaurs but they continued to exist along with dinosaurs.

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
