What is the best description of organisms of the precambrain era?

a.) land plants and animals
b.) dinosaurs in primitive mammals
c.) single celled organisms and soft, bone less animals
d.) ferns and flying reptiles

The correct answer is option C. Single celled organisms and soft, bone less animals. The Precambrian ear was believed to be before evolution. Meaning   more plants and  complex animals. Therefore, organisms were single celled during that time.

Hope I could help! :)

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
