Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). Entamoeba histolytica is a protozoan. A microscope is necessary to view this parasite.
The scientific revolution began in Europe towards the end of the Renaissance period and continued through the late 18th century, influencing the intellectual social movement known as the Enlightenment.he concept of a scientific revolution taking place over an extended period emerged in the eighteenth century in the work of Jean Sylvain Bailly, who saw a two-stage process of sweeping away the old and establishing the new.
The Renaissance encouraged individualism and therefore more people questioned the authority of the Church. Just to oppose the Church, people began to encourage scientists to prove theories and not just be the Church's parrot and listen to whatever the priests said. Slowly, scientists came up with theories and their research that soon proved true. This is how the Renaissance started off the Scientific Revolution.
