Planarians - Study guides, Revision notes & Summaries

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...

Phylum Porifera - ANSWER simple, sessile (permanently attached to one location) sponges; no tissues, organs, mouth or digestive cavity; filter feeders: flagellated collar cells line the large internal cavity and draw water into the sponge (food particles are strained out of the water current by the collar cells which pass food to other sponge cells); acolemate (no colon); no symmetry; most are marine Phylum Cnidaria - ANSWER class hydrozoa, class scyphozoa, class anthozoa; jellyfish, sea anem...

Osmoregulation and Excretion Quiz Top of Form Question 1 Correct Mark 1.00 out of 1.00 Flag question Question text Why does urine contain a higher concentration of wastes (be hypertonic ) than the blood? Select one: a. Urine cannot since the process is passive diffusion b. Reabsorption of water and salt in the loop of the nephron and collecting ducts leaves behind more concentrated urine c. All stages in the kidney involve active transport d. Urine can be hypertonic for small molecules if it is ...
