Biology Lab Report on the Effects of Adrenalin on a Daphnia

Abstract
For this experiment we tested the effects of different adrenalin concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a slide with cover slip in order to examine its heartbeat by using the microscope.
Aim
In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia, the water flea.
It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations, in terms of heart rate.
Background
The endocrine system works with the nervous system to regulate and coordinat…
