Structure and function of the circulatory systems in insects

Reference no: EM1394770

Question: Which molecules and ions (phenolphthalein, iodine, starch, Na+, OH-, water) does your experiment give evidence for passage through the semipermeable membrane? Also, in which direction (into or out of the bag) are the molecules moving?

Question: Compare and contrast the structure and function of the circulatory systems in insects and in mammals. [Hints: explain why each animal's system works for that animal. Don't ignore gas exchange; it's connected with circulation.]
