PPT-Effect of Stimulant on Pulse Rate of

Lumbriculus Variegates By Julia Lawrence and Kirsten Liddle Introduction For this experiment we tested a stimulant on Lumbriculus Variegates to observe the effect on its pulse rate Lumbriculus Variegates . 1. Students hypothesized that water pollution affects the growth of fish. In an experiment, they added the same amount of food to ponds polluted by fertilizers and industrial waste. They measured fish growth and found that most fish grow slowly in each of these environments. Why is their conclusion not reliable?. . Presentation PhD-research. Drs. Ir Maarten Soetaert.

They are used for pulse rate testing because they have transparent skin which allows one to easily observe it’s closed-circulatory system. Black worms are commonly found in shallow bodies of water such as marshes, ponds, or lakes. This experiment is testing the effects of depressants on the worm’s pulse rate. Our group made the hypothesis that if a worm lives in depressant water, then it will have a slower pulse rate than a worm living in plain spring water. . By: Jared Fearby and Sarah Kuehne. Albion High School. Genesee Community College Bio 100 . Introduction. :. The . Lumbriculus variegates, . better known as the blackworm is a type of Phylum Annelid with two cell layers, tissues and organs. they have transparent skin, this makes blackworms good for studying pulse rates due to being able to easily see there circulatory system. We are using alcohol as our toxin to test on blackworms. C2H6O otherwise known as ethanol is the main ingredient in many alcoholic drinks. Alcohol can be lethal if enough is consumed. Although every person is different a blood alcohol content of .30% or higher can be lethal. Some common effects of alcohol are Slurred speech. . 2. Brainstem stimulants (. Medullary.
