The correct answer is Three germ layers. The feature, three germ layers, is only shown by higher invertebrates, as compared to lower invertebrates. The formation of the three germ layers is caused by the morphogenetic movement called Gastrulation.
Answer:
Cell level organization
Explanation:
Organisms are composed of different level of organizations like atomic level, molecular level, cell level, tissue level, organ level, system level after which whole organism if formed.
If we talk about <u>Arachnoidiscus</u> <u>ehrenbergi </u> it is one celled organism belonging to a group of algae. If we talk about human stomach it is an organ made up of several tissues which in-turn are made up of several cells.
So what is common in both?
It is a cell that is common in both, because cell is the basic unit for life of <u>Arachnoidiscus</u> <u>ehrenbergi </u>and a unit of the composition of whole stomach.
