Why is comparative serology done?

Comparative serology is done to determine and confirm the natural relationship of animals due to similarity of blood proteins. The relative degree of precipitation of serum from one group of animals will give idea about closeness between them. The serum of closely related animals is unable to cause precipitation, whereas those of distantly related animals causes highest precipitation.

If current in an electric bulb drops by one percent, what happens to the power?

Define: a. Perkin's condensationb. Aldol condensationc. Cannizaro reactiond. Benzoin condensation e. Wolf Kishner reactionf. Carbylamine reaction 

a. Perkin's condensation:The reaction between an aromatic aldehyde and the anhydride of an aliphatic acid in the presence of sodium salt of the same acid, leading to the formation of an alpha, beta unsaturated acid is called Perkin's reaction. For example, benzaldehyde and acetic anhydride give cinnamic acid.

benzaldehyde + acetic anhydride --CH₃COONA (455K)----> Cinnamic acid + CH₃COOH

b. Aldol Condensation:Aldehydes and Ketones having at least one alpha-hydrogen atom in the presence of...
