Consider that you have access to use fluorescent tagging of specific proteins and view cells in a confocal microscope. You isolate a cell with the fluorescent dyes, showing that a very tiny, single-celled organism has not only a cell membrane, but internally folded membranes. You determine also that the membranes do not completely surround internal specialized compartments of the cell. You identify this as

the titanic would be the correct answer

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
