  • Essay / UV Radiation on Organisms - 862

    This project is important because it could help better understand how UV wavelengths affect people and the ozone hole. By determining the effects of UV on Artemia Salina, we are one step closer to mitigating the effects of UV rays on organisms. In the future, this could lead to better UV protection technology.IV: UV exposure in secondsDV: Mortality rateDV2: Growth rate in mm/dayH1=UV radiation will kill more shrimp as they will be exposed to it for a long time.H2=artemia are more numerous. likely to form defects and some form of stunted growth.N1= UV will have no effect and there will be no deformation or conditions of any kind on Artemia Artemia are small crustaceans that live on coasts inland salt flats, including species like brine shrimp and crayfish. These invertebrates are small and are generally difficult to see in the water, have hard exoskeletons and small legs that are very difficult to see. Males give birth to young through egg-laying cysts, while females produce offspring through live birth. They have existed since the Triassic period. Prehistoric fish sometimes ate Artemia and other times got picked up by hovering birds. Artemia Salina or Sea Monkeys only go to near shore waters, as most of the salt is found far from shore and Artemia can only survive in certain salinity levels, making it a little more difficult to grow in salt tanks. But when saline solution levels are perfect, they give optimal experimental results. They have almost no defenses but multiply quickly and are fast swimmers. Brine shrimp are also extremely common in marine stores and are used for human or fish food as well as a variety of science projects and have a high sales rate even for their sometimes high price. ..... middle of paper ......now that they have hatched, the shells can no longer protect them from UV.)5. Recount the larvaeRecount the larvae in exactly the same way as before. The larvae after radiation should have had some form of UV effect, such as low average amount, dead larvae, etc... (Note: if you want to count again, because you didn't see any effect , it would be recommended because UV radiation does not always have instantaneous effects.)List of materials (In order of use)1 bottle of Artemia Salina eggs4 culture dishes1 UV4 lamp 500 ml.

Make a graph representing the number of brine shrimp per 0.5 ml drop when counting brine shrimp.2. After the count, compare the averages of past counts with current ones to find a possible mortality rate..
