Bone‚ in the human body‚ performs a number of mechanical and physiological functions‚ including mechanical support‚ movement and protection of vital organs. It is a complex tissue that undergoes constant repair and remodelling to its micro-architecture caused as a result of biomechanical forces imparting trauma and homeostatic insults. [1] The basic unit of bone is an osteon‚ which is made up of concentric lamellae of compact bone surrounded by a Haversian canal. There are two components to bone

Title:Identification of Amino Acids and Proteins Introduction : Amino acids are molecules containing an amine group(NH3)‚ a carboxylic acid group(R-C=O-OH) and a side-chain( usually denoted as R) that varies between different amino acids. The key elements of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form in a biologically functional way. A polypeptide is a single

Introduction Humans live with secrets. Some of those succeeded in keeping them hidden to their graves‚ while others might not be as fortunate. For centuries‚ humans were tortured and many were killed either for keeping or revealing them. One of the fears and struggles that one must keep is the deepest personal information: their sexual orientations. Those who have “different” sexual orientations from the generally known and accepted by the society have to live in shadows and try to blend in among
