In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

IRON ORE DRY BULK TRADE Demand for dry bulk commodities like iron ore is driven by industrial production and growth requirements. An increase in steel production stimulates the growth of iron ore shipments and also the trade. From early 2000s‚ the iron ore market began a transformation following China’s increasing demand for steel. World production of iron ore exceeded 1 billion tonnes in 2002. International iron ore trade reached record levels at 512 million tonnes (Mt). Price negotiations
