The world's biggest container ships have 109,000 horsepower engines which weigh 2,300 tons. Each ship expects to operate 24hrs a day for about 280 days a year. There are 90,000 ocean-going cargo ships. Shipping is responsible for 18-30% of all the world's nitrogen oxide (NOx) pollution and 9% of the global sulphur oxide (SOx) pollution. One large ship can generate about 5,000 tonnes of sulphur oxide (SOx) pollution in a year
(October 2007) A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) (from the Greek word ÏÎµÏÎ´Î¿ÏÎ¿Î´ÏÏ, ÏÎµÏÎ´ÏÏ false + ÏÎ¿Î´ÏÏ foot) is a temporary cytoplasm-filled projection of a eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter.
Pseudopod Function. Pseudopods are actually extensions of the cytoplasm, or the thick liquid that is inside organisms like amoeba. The organism can change the shape of the pseudopod making it move, appear and disappear.The pseudopods are used in movement and as a tool to capture prey.In order to move using pseudopods, the organism pushes cytoplasm towards one end of the cell which makes a projection, or pseudopod, off the cell.he organism can change the shape of the pseudopod making it move, appear and disappear.
