Explanation: A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is:
A+BC \rightarrow AC+B
In this general reaction, element Ais a metal and replaces element B, also a metal, in the compound. When the element that is doing the replacing is a nonmetal, it must replace another nonmetal in a compound, and the general equation becomes:
Y+XZ \rightarrow XY+Z
Yis a nonmetal and replaces the nonmetal Zin the compound with X.
Metal Replacement
Magnesium is a more reactive metal than copper. When a strip of magnesium metal is placed in an aqueous solution of copper(II) nitrate, it replaces the copper. The products of the reaction are aqueous magnesium nitrate and solid copper metal.
\text{Mg}(s)+\text{Cu(NO}_3)_2(aq) \rightarrow \text{Mg(NO}_3)_2 (aq) + \text{Cu}(s)
This subcategory of single-replacement reactions is called a metal replacement reaction because it is a metal that is being replaced (copper).

It is either blending inheritance or merging inheritance. They both mix the parents' genes to produce conditions for their future offspring.
In the ovule. When the 'pollen', which are the sperm of a flower, reach the stigma, the 'pollen' will roll down through the style to the ovary.
