What is Displacement reaction?

Displacement reactions:

We can also judge reactivity by putting the metals into competition with each other.

The metals will 'fight' each other to 

'win their prize' - oxygen.

The more reactive metal will win the competition.

Copper starts off with the oxygen in copper oxide.

However, iron is more reactive, so it takes the oxygen away from copper.

We say that iron has displaced the copper.

copper oxide + iron _ iron oxide + copper

This is a displacement reaction.

iron oxide + copper ----X no reaction

A more reactive metal can displace a less reactive metal from its compounds.

Define Pedigree and Carrier.

Define Pedigree and Carrier. Pedigree: A pedigree is a chart used to trace the history of traits in a family. They are used to study   heredity patterns. Parents and offspring are shown in a pedigree.   Horizontal lines connect parents, and vertical lines connect parents to offspring. Males are represented as boxes ; f e mal e s ar e shown as circles. Individuals with a dominant trait have a shaded shape . Unshaded shapes represent recessiv e individu a ls . C arrier : A carrier is any individual who has inherited the gene for a trait, but does not show that trait  physically.
