Cat. 856 Ennvironmental Toxicity Response in C. elegans For 10 Groups. Caenorhabditis elegans is a soil nema- tode with great potential for educational research, partly because of its rapid (3-day) life cycle, small size (1.0-mm-long adult), and ease of laboratory growth cultivation. In this experiment, students will observe and compare the effects of heavy metals found in the environment on normal and mutant strains of Cae- norhabditis elegans (C. elegans) .
Cat. 851 Effects of Alcohol on C. elegans
For 10 Groups. You will not believe how similar we are to worms! The genome of the tiny worm, C. elegans , was sequenced and found to be 40% similar to the human genome. It is now used as a model system by researchers to address fundamental questions in developmental biology, neurobiology and behavioral biology. The objective of this experiment is to observe and record the effects of alcohol on normal and alco - hol mutant strains of C. elegans .
Cat. 852 Chemotaxis: The Science of Attraction in C. elegans For 10 Groups. All organisms are affected by “scent” molecules in the environment, including a multicellular organism called Caenorhabditis elegans. These worms are composed of 959 somatic cells, of which 300 are neurons comprising organs for taste, smell, temperature and touch. In this experiment, students will observe and record the phenomenon by which normal and mutant strains of C. elegans can direct their movement in re- sponse to certain chemicals in the environment.
