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.
Activity series or reactivity series can be used to compare the reactivity of different metals. The series of elements in which they are arranged in the increasing order of their reactivity is called as activity series. A replacement reaction takes place when one metal replaces the other in its aqueous solution.he activity series is a list of elements organized according to their tendency to react (their reactivity). The more readily an element reacts with other substances, the greater is its activity. A list of all the elements and their reactivity can be summarized in the form of a table.
