Basics of diffusion, gradients, and how they relate - Answer-Diffusion: spontaneous movement of very small things. It requires no energy investment by the organism (other than keeping the temperature above freezing) --direction is random Gradients: top of gradient = high concentration, bottom of gradient = low concentration --diffuses high to low Basics of diffusion across a semipermeable barrier - AnswerFactors that speed up or slow down diffusion - Answer-size: smaller things diffuse fas...

MIP 260 Exam 3Cestoidean - correct answer Strobila; Made up of many individual "proglottids"; Strobilation (formation of new proglottids) - takes place at the anterior end of the worm; The older proglottids are near the posterior end of the worm Cestoidea - correct answer The tegument and muscle fibers of the tapeworm are continuous... therefore cestodes are not technically "segmented" like annelids or arthropods, even though we commonly refer to their segments or proglottids Cestoid...
