Uma ameba que tivesse seu habitat no meio marinho, sendo isotônica em relaç?o a esse meio, com certeza poderia dispensar em sua estrutura a presença de: A) membrana plasmática B) pseudópodes C) vacúolo contrátil D) membrana celular E) microtúbulos

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
