What kind of electric cell is considered to be rechargeable?
a. storage cell
b. dry cell
c. primary cell
d. electrode cell

a. Storage cell

Explanation:

A Storage cell is an electric cell that can be recharged. During recharging of a Storage cell, current flow is reversed and oxidation occurs on the positive electrode and reduction on the negative electrode. Since the anode is by definition the electrode on which oxidation occurs and the cathode where reduction occurs, the positive electrode is now the anode and the negative is the cathode.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
