Ethnography is the study of social interactions, behaviours, and perceptions that occur within groups, teams, organisations, and communities.
Then the cell divides in half, with one Paramecium above the other, like a short totem pole. Paramecium also reproduce sexually, and this is really weird. Two compatable cells join belly to belly and part of their cytoplasm fuses (kind of like a siamese twin). For sex, they do not need their big macronuclues: it is slowly destroyed.
As with the ameba, oxygen and carbon dioxide pass through the cell membrane of the paramecium. The paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction.
