The quest for knowledge is at the heart of science. We all have the right to our own opinions as human beings, but we do not have the right to our own facts. A fact is reality as we understand it, and truth is discovered via scientific procedures. Based on their observations and current understanding of the subject, scientists will formulate a null hypothesis about how it functions. They will then conduct an experiment, evaluate the results, and reject the null hypothesis. Being skeptical, the scientist either rejects the null hypothesis outright or fails to do so in light of the data analysis. Eventually, scientists write up the results of the experiment in the form of a research paper and submit it in a journal related to the specialtyin question. (cf. p.11) * (cf. p.11) Nair, P.

Cette matière permet aux étudiants d’appréhender la complexité de la  notion de toxicité et les outils d’évaluation de l’impact des substances toxiques sur les organismes vivants et de leur comportement dans le milieu physique.
