Brine shrimp

Results Samples of Artemia eggs were exposed during three days to four different salinities: 0%, 0.5%, 1% and 1.5 %. After gathering all the results, one may observe the level of salinity that contributed to the larger hatching success of Artemia. The sample exposed to a salinity of 0.5% exhibited the greatest hatching whereas the sample exposed to the solution with no salt, or 0% salinity, did not show any hatching nor partial hatching (Table 1). The sample exposed to a 1.5% salinity presented

The purpose or the significance of the experiment was to see if brine shrimp can survive in different salinities of saltwater. The experimental (alternative) hypothesis was supported, because in figure 1 it showed that there was an increase of the average (mean) of survival rate of the brine shrimp when the salinity level (in grams) increased. It was in Figure 1 and it shown that the rates had higher numbers (increased survival rates) and the lower salinities had lower survival rates. The raw data

Our end results only supported to some extent our hypothesis that increasing numbers of brine shrimp would directly cause decreases in algae concentration. Our hypothesis, if applied to only the jars of 3 and 6 brine shrimp, would be highly supported, due to the significant difference in algae concentrations. Evidently, the more shrimp that were present in the ecosystem, the less algae that were available at the end. In an ecosystem with more consumers, the consumers demand a higher amount of nutrients

Abstract 1 As a biological model for the preliminary selection of components from a natural source, brine shrimp is lethality test. Clove essential oil obtained by hydro distillation and essential oil of Eucalyptus were purchased. Acquire from aerial parts, extracts and essential oil of D. furfurada did not show activity, but the essential oil from underground was functioning. (Brandao, et.al, 2013) Abstract 2 As an aftermath of the advancement in technology, the useful life of electrical

Iodized table salt: This is the most type of salt used in homes and kitchens. It is called “Iodized” because today, most salt manufacturers fortify the salt with mineral Iodine. It is an essential mineral for fighting off certain Iodine-related diseases like hypothyroidism. There’s also another natural way to get this important mineral into someone’s system by eating more seaweed, which is rich in Iodine. Sea Salt: Made from evaporated water in the sea. Their are larger and coarser crystals of salt

solution for the brine shrimp was the 1.0 petri dish because it wasn't too concentrated and it wasnt too little. Explain, in terms of natural selection, why one saline solution yielded the highest hatching viability of brine shrimp. Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. One saline solution yielded the highest hatching viability because only one of the solutions was suitable for the brine shrimps and they were

microalga Dunaliella tertiolecta and the brine shrimp Artemia franciscana , respectively prey and predator. PS NP behavior in exposure media was determined through DLS, while their toxicity to microalgae and brine shrimps evaluated through 72 h growth inhibition test and 14 d long-term toxicity test respectively. Moreover, the expression of target genes (i.e. clap and cstb), having a role in brine shrimp larval growth and molting, was measured in 48 h brine shrimp larvae. A different behavior of the two

amounts of ethanol alcohol and their viability was measured. The hypothesis used was if there is more ethanol alcohol, then the viability of the brine shrimp is unfavorable. The brine shrimp were put into sixteen Petri dishes with the same amount of brine solution. Different amounts of ethanol alcohol were added to each Petri dish. After 168 hours, the brine shrimp were

3. Brine shrimp have survived successfully since the Triassic period, around 200 million years this has been possible through their unique adaptations which have enabled them to avoid predators and suit their environment. They are pretty good at surviving except in space (who knew radiation isn’t good for shrimp). One of the best adaptations the brine shrimp have is their ability to survive in waters of very high salinity (up to 25%). There optimal levels of salinity are 3-3.5% but they are rarely

finding seemed to support our original hypothesis that the colored wavelengths would negatively affect the brine shrimp development.
