Select correct statement regarding silver extraction process.

When the lead-silver alloy is rich in lead, lead is removed by parker's or pattinson's process which includes desilverizing argentiferous lead by repeated meltings and skimmings, which concentrate the silver in the molten bath, the final skimmings being nearly pure lead. Zinc forms an alloy with silver, from which zinc is separated by distillation.

The Process of Meiosis | Biology 171

Meiosis I. Meiosis is preceded by an interphase consisting of G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. Finally, in the G 2 phase (the “second gap phase”) the cell ...
