Fish cold-blooded‚ limbless‚ completely aquatic vertebrates‚ having gills‚ commonly fins‚ and typically elongated torpedo-shaped body mostly covered with scales. Fish are usually grouped into four classes‚ three living (Agnatha‚ Chondrichthyes‚ and Osteichthyes) and one extinct (Placodermi): 1. Agnatha‚ the primitive jawless fishes‚ including the cyclostomes (lampreys and hagfishes) and extinct armoured fishes known as ostracoderms‚ none of which has gill arches (bony frames for the gills);

The Fish by Elizabeth Bishop Bishop uses literary devices‚ especially similes‚ metaphors‚ tone‚ and imagery to convey her theme of admiration for survivors of life’s difficult battles‚ in this case the fish‚ although at first she failed to admire and appreciate the fish. Bishop also doesn’t realize how beautiful the fish is at first‚ but she eventually finds beauty in the fish. Bishop’s tone of aloofness in lines 5-10 shows that first she is disappointed in what she thought was a big catch.

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

Oxygen Exchange and Transport Oxygen exchange or respiration takes place at a respiratory surface; a boundary between the external environment and the interior of the body. Gas exchange is the process by which oxygen and carbon dioxide (the respiratory gases) move in opposite directions across an organism’s respiratory membranes‚ between the air or water of the external environment and the body fluids of the internal environment. Oxygen is needed by cells to extract energy from organic molecules

OXYGEN-CARBON CYCLE The carbon-oxygen cycles are actually two independent cycles. However‚ both these cycles are interconnected as well as interdependent on each other to some extent. There are four processes involved in the completion of the carbon-oxygen cycle. Oxygen-carbon cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis‚ plants take in carbon dioxide (CO2) and absorb water (H2O) with the help

If a plant makes 30 grams of glucose (C6H12O6)‚ how many moles of glucose has it produced? 0.17 moles The health of bones depends upon a good supply of calcium. If a person consumes 0.06 g of calcium‚ how many moles of calcium did he consume
