WebThe third method of avoiding the nocuous stream, contraction into the tube, may last about half a minute, when the Stentor expands again. It does not then repeat the previous reactions, of turning away and reversing the current, but if the nocuous stimulus is still present it contracts again, repeating this response many times, during a period of 10-15 … Webiikrnent: if the initial stream speedis U, the filament U+u, with u< U, and the iimd stream speed is lU, then thefinal iilament speed must be lU+l-%; that is, con-traction reduces the longitudinal perturbation veloci~ u,by thefactor J-’.
