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.
The Yellow Sponge can only reproduce asexually through gemmulation. Gemmules are internal buds found in sponges that are a response to a hostile environment.They are resistant to drying out, freezing, and lack of oxygen, and can lie around for long periods of time.
