Example Input: When it interacts with ryanodine receptors, this element upregulates its own release, and this compound forms the cell plates of coccolithophores.

Parafollicular cells of the (*) thyroid produce a compound that reduces the concentration of this ion in blood, and its intestinal absorption requires vitamin D. This ion interacts with Troponin to stimulate muscle contraction, and the lumens of sarcoplasmic reticula have high concentrations of this ion. For 10 points, name this divalent cation that is stored in bones.
Example Output: Science

Example Input: In his Autobiography, this philosopher priviliged Plato, Tacitus, Francis Bacon, and Grotius above all other thinkers, and he modeled his own efforts after Grotius, whose work led him to conduct the research that led to the writing of a treatise which pondered the question of whether justice is natural or conventional. This thinker juxtaposed the arts of "criticism" and "topics" in the first of his major anti-Cartesian works, On the Study Methods of Our Time, and later added to his work Universal Right a volume entitled De constantia jurisprudentis, this first chapter of which would lend its title to this man's most famous work. More famously, this man is famous for a work which reformulated the verum factum principle he himself had proposed in his On the Most Ancient Wisdom of the Italians and advanced the notion of three universal principles, those of religion, marriage, and burial. For ten points, identify this thinker who proposed a cyclical theory of history in his most famous work, The New Science.
