The layered appearance of foliated metamorphic rocks is due to the a) recrystallization of minerals. b) mechanical deformation of sheet-structured minerals. c) laying down of micaceous minerals, layer upon layer. d) realignment of sheet-structured minerals so that they are perpendicular to compressive forces.

The answer is a) carbon-12

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
