metal ion and so dative covalent (co-ordinate) bonds hold a complex together. The central metal ion with vacant bonding orbitals can act as a Lewis acid. Ligands act as Lewis bases by electron pair donation to form the metal-ligand bond. Bronsted-Lowry acid-base theory reminders (essentially a sub-set of Lewis Theory) A base is a proton acceptor. This is via an electron lone pair on the base (a Lewis base is a lone pair donor). e.g. NH3‚ HCO3-‚ OH- etc. An acid is proton donor. This involves

Introduction What is Protein? There are more than 300 amino acids in the nature. However‚ only 20 amino acids are joined by each other with peptide bonds in different sequences and numbers. These sequences are formed by helping of genetic information which is encoded in genes. So‚ each protein molecule has its own amino acid sequence. Proteins are most abundant long chain macromolecules in all cells and they serve as structure and function matter in cells of all living organisms such as hormones

In "The Giver" the society is set up to ignore and reject individuality. Each person is assigned a job and purpose and they are taught not to question anything. Though it seems like our society
