Though other types of life may share some of these characteristics, the set of characteristics as a whole provide a distinction from the other kingdoms. The set of characteristics provided by Audesirk and Audesirk are: 1  Animals are multicellular.2  Animals are heterotrophic, obtaining their energy by consuming energy-releasing food substances. 3  Animals typically reproduce sexually. 4  Animals are made up of cells that do not have cell walls.he set of characteristics provided by Audesirk and Audesirk are: 1  Animals are multicellular. 2  Animals are heterotrophic, obtaining their energy by consuming energy-releasing food substances. 3  Animals typically reproduce sexually. 4  Animals are made up of cells that do not have cell walls.
The activity series is a useful guide for predicting the products of metal displacement reactions. For example, placing a strip of zinc metal in a copper(II) sulfate solution will produce metallic copper and zinc sulfate, since zinc is above copper on the series.op-ranked metals displace the ions of metals lower in the series from solution. A free-energy based series is used in this tutorial to show how and why active metals displace less active ones from solution.
Not to be confused with Electrochemical series. In introductory chemistry, the reactivity series or activity series is an empirical, calculated and a structurally analytical progression of a series of metals, according to their reactivity from highest to lowest.
