Finally‚ they decided to hold a class

Salt is what the brine shrimp need to hatch. Without salt the brine shrimp won’t be able to hatch or stay alive long. My question ‘Which water will the brine shrimp thrive the best in with with the different amounts of salinity?’ These next paragraphs are some of the information on brine shrimp. For example what they look like‚ eat‚ etc. This experiment will test whether it matters how much salinity is put in with the eggs. Brine shrimp live in very salty water. Adult brine shrimp are called Artemia

Title of Experiment: The Effect of Temperature on the Hatching Success of Brine Shrimps. Abstract In this experiment‚ 40 brine shrimp eggs are put into a test tube containing salt water at different temperature such as 25°C and 35°C respectively. The eggs are left from two days to hatch. After two days‚ the number of eggs successfully hatched are observed and counted. Introduction Brine shrimp is the common name for a primordial crustacean that reaches less than 1.3 cm in length and is usually

Chitin is one of the most abundant polysaccharide in nature‚ being only second after cellulose. It can be found in animals (exoskeletons of crustacean and insects) as well as in fungi‚ mushrooms and yeasts. Chitin can be described as a biopolymer composed of N-acetyl-D-glucosamine; a chemical structure very close to cellulose except that the hydroxyl group in C of cellulose is replaced by an acetamido group in chitin. One can associate this chemical similarity between cellulose and chitin as serving
