The two ions are SODIUM AND CALCIUM IONS. Polarization refers to loss of polarization, that is, loss of the difference in charge between the inside and the outside of the plasma membrane of a muscle due to a change in permeability and migration of ion. When a heart muscle is depolarize, sodium ion and calcium ion channels open and they migrate into the cell from the outside.

Answer:
yes, gold can be created from other elements. The process requires nuclear reactions and is so expensive that currently it would cost a lot more than the price of natural gold available, therefore, unprofitable. Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, gold can be created by simply assembling 79 protons, (and enough neutrons to make the nucleus stable).
In an endothermic reaction, the heat enthalphy of the products is greater than the heat enthalphy of the reactants. In this case, an increase in temperature favors the formation of more products via Le Chateliers principle. This change is equal to that Keq will increase.
