                                List Of Wildlife Sanctuaries  Protecting wild plant and animal species and their habitats is known as wildlife conservation. In addition to preserving nature for future generations to enjoy, wildlife conservation aims to raise awareness of the value of wildlife and wilderness areas for both people and other species.

                          Phylum Mollusca (clade) – mollusks  very successful phylum: over 93,000 named, living species The largest number of living species for animals after Arthropoda  mostly aquatic, but over 35,000 terrestrial species (more than all terrestrial vertebrates)  includes snails, slugs, clams, oysters, chitons, cuttlefish, octopi, etc.  from microscopic to 21 m (giant squid – largest invertebrate)  economically important (food, ornamentation, currency, pests)  Defining Characteristics Of Mollusks:   Bilateral symmetry with true coelom ; usually have a differentiated head unsegmented (some argument as to whether lost during evolution or never present in phylum)   Three main body parts : muscular foot, visceral mass, and mantle muscular foot – used for locomotion, food capture, attachment  · may be solid or have tentacles or maybe a “wing” or fin in pelagic forms · covered with soft epithelium and  · may secrete mucus to glide on    Visceral M

                                                                                         Cell Cycle In every organisms Cell continuously undergoes a series of events like growth , development & reproduction and completes its life cycle called the Cell Cycle . After the formation  of the Cell , it  first goes  under   resting period where they grows in size, its nuclear material increases, and prepare itself  for the next division. Duration of cell cycle - The duration of the  every cell cycle varies to  25 – 30 hr in different cells except  in case of  organisms like in Ecoli, the cell cycle is completed in 20 minutes, Stages of the cell cycle – Interphase - Interphase is the interval period between two successive divisions when the cell does not show any division. But it prepares itself for it by synthesizing new proteins and nucleic acid. This phase is also known as the preparatory phase. G1 Phase - It is the first gap phase where the cell grows physically

                                     Amino Acid Amino acids are organic compounds containing amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid. Amino Acids Structure Amino acids have the general form H2NCHRCOOH. (or)   General properties of Amino Acids ·          Amino acids are soluble in water and insoluble in hydrocarbon solutions. ·          They are crystalline solid substances. ·          They have very high melting point compared to their boiling point. List of Amino Acids There are around twenty amino acids, which are involved in the construction of proteins. The lists of twenty amino acids are: Alanine, aspartic acid, asparagines, arginine, cytosine, cysteine, glycine, glutamine, glutamic acid, histidine, isoleucine, leucine, lysine, methionine, Proline, phenylalanine, serine, tyrosine, threonine, tryptophan and Valine , Essential Amino Acids   The
