Which taxonomic domain includes multicellular photosynthetic organisms? see concept 1.2 (page 12)?

Answer

           According to modern system of classification all living organism come under the category of super kingdom known as domain.

Classification of domain

         Domain is classified into three main category. these are:

1. Archaea

                Archaea include prokaryotes bur differ from bacteria as archea plasma membrane include different tpes of lipids. Cell wall of archaea have no peptidoglycan and also contain different types of RNA.

2. Bacteria

             It also include single cell prokaryotes but differ from archaea ob the basis of cell wall composition, RNA and lipids present in plasma membrane.

3. Eukarya

            It include all eukaryotes which are unicellular as well multicultural.

Conclusion

         Thus is is confirmed that multicellular photosynthetic organisms come under the category of Eukarya.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.
