What structures to eukaryote cells have that prokaryotes do not? 1. nucleus
2. celle membrane
3. mitochondria
4. endoplasmic reticulum

not too sure but maybe in the hot springs.

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.
