Another flagellum runs along the length of the cell body and extends to the posterior part of the cell. In some species, this flagellum is characterized by two vanes at the free posterior end. * Most of the cells in the order Trimastigida range between 11 and 17 um in length and 7 ...
Another name is horsetail because roots arise from underground rhizome nodes, scaly leaves, and stems. For example- equisetum. The plant stem has different internodes and nodes, and they are arranged in whorls. Equisetum is the only living genus that is homosporous, ...
To put it another way, the skin cell and the liver cell are different ontologically because they are orga- nized and behave differently. Thus, contrary to Schindler's argument, we can reasonably and with certitude conclude that an OAR-generated entity that becomes a tumor is ontologically ...
