Where does metaphasen1 occur

Explanation: Metaphase - In metaphase I, chromosomes align along the center of the cell. In metaphase II, pairs of sister chromatids line up in the center of the cell. Anaphase - Chromosomes are pulled apart by the mitotic spindle. In anaphase I, sister chromatids stay together

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.
