Answer:
B. functional body cavity lined by tissues derived only from endoderm
Explanation:
From the word "Pseudo" means false i.e something that is not true or literally acting in place for a particular real subject.
Coelom on the other-hand is an fluid-filled hollow cavity that act as the skeletal structure for an organism. They act helps serves as cushion effects for the organism.
Ceolomates are organism that have ceolom and the body tissues are derived from the mesodermal layer that lined the body cavity of organism possessing these ceolom.
But in pseudocoelomate they do not have a true ceolom, but there functional body cavity lined by tissues derived only from the endoderm.
The answer is most likely: 'with an abundance of plant life without oxygen in the atmosphere '. The atmosphere contained almost no free oxygen during the Archean. It does not appear as if this epoch had an abundance of plant life, but rather mats of single-celled photosynthesising cyanobacteria. So I am not completely sure that either of the given choices are correct.
The correct answer is by composition and texture. Composition is that minerals that the rock are made of. Texture refers to the grain size of the different components of that rock. Texture has to do with sizes of mineral grains and other constituents in a rock and how the sizes and shapes relate to each other.
