Biology 10 Vinegar Eel Lab Adam Dorner 1) The most toxic metals were silver‚ lead and iron‚ all killing the eels in under four minutes‚ with silver taking only 1 minute and 40 seconds to kill the eels‚ and only 13 seconds to make the eels stop forward motion. Strontium wasn’t effective as after 5 minutes of exposure to it‚ the eels hadn’t died or stopped forward motion. 2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0.0012 parts per million‚ however

Part 2: Effects of Environment on Mitosis. Experimental Hypothesis: If we put onion root tips in IAA solution then the rate of Mitosis will increase. Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a
