Animal tissues develop from embryonic germ layers. triploblastic animals have three germ layers (ectoderm, mesoderm, and endoderm) and three basic body plans related to body cavities (acoelomate, pseudocoelomate, and coelomate). select the three statements that are true. to review the germ layers and the terminology associated with body cavities, see the hints.

Answer;

The three statements that are true, include;

A diploblast has no mesoderm.

A pseudocoelom has the same functions as a true coelom.

In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.

Explanation;

-Diploblastic animals are animals possessing two major tissue layers. These include the outer layer (the ectoderm) and the inner layer (the endoderm). Unlike the triploblastic animals , the diploblastic animals lack the third middle layer, the mesoderm.

- Coelom is the body cavity which exists between the mesoderm and endoderm while pseudo coelom is the body cavity which is present inside the mesoderm. Both the coeloms and pseudocoeloms are used as hydrostatics skeletons.

-Coelomate animals are animals that have a "true" body cavity or coelom and organs are in cased in peritoneal membrane.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
