By way of example some of the most polluted parts of the planet are lakes like that explained in our research laboratory. Once pollution occurs pets or animals can be damaged in many ways possibly to the brink of loss of life.

To avoid this a real-time assay can be performed. This really is a short timed test that individuals use to gauge the effect of pollutant on organism by choosing the smallest attention possible that could still be a bother. This is a very important tool since we can get direct results from money organism by simply detecting anxiety signals bleary a short period of time allowing for us u fix the problem faster. Using a great organism to get the assay is the best choice because there are many parameters that can be used to identify stress on the subject because of a certain input.

Materials and Methods

Everything is kept similar in every test except when ever concentration differences need to be changed. Meaning almost all lighting, warming, vibration daphnia numbers will never change to be sure there are little changes and differences in the experiments. The sizes in the daphnia are also better to become kept around the same. Daphnia are really speedy so selecting something to measure within a two-hour time period made it better to narrow it down to heart rate. Since we could control their space, that means less part of movement we can see their cardiovascular system better.
