(2pts) Homeostasis is the maintenance of certain steady states in a fluctuation environment. Since negative feedback causes a reaction in the opposite direction as the initial deviation is results in equilibrium (equalizing the reaction as the example with the heater) 5. List some adaptive features of the tapeworm and planaria. (2 pts) Some adaptive features of the tapeworm are scolex (hooks and suckers), cuticle protects against digestion, great reproductive potential, and the tapeworm does not kill the host. The planaria have auricles which are sensitive to stimuli and eye spots which are sensitive to light. They can reproduce both sexually and asexually. They both have well-developed reproductive systems and muscular systems....
