Which of the following statements about deuterostomes is false? all deuterostomes have a similar pattern of early embryonic development. all deuterostomes are triploblastic and have three tissue layers. all deuterostomes have a coelom. all deuterostomes exhibit radial symmetry in their bodies.

The false statement is: All deuterostomes exhibit radial symmetry in their bodies.

For example, phylum Chordata contains animals that don’t have radial symmetry.

Deuterostomes share characteristics such as coelom that forms from folds of archenteron, radial, indeterminate cleavage, anus formed from blastopore.

The major distinctions between these two groups of animals (Bilateria) deuterostomes and protostomes are in their embryonic development. Another difference  is that most Protostomes have schizocoelous development (cells fill in the interior of the gastrula and that is the way the mesoderm is formed) On the other side, in Deuterostomes, the mesoderm forms through invagination of the endoderm (enterocoelic pouching).

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
