These two systems work together and respond to homeostasis - ANSWER Nervous and endocrine Chemical signal from nervous - ANSWER Sends message along nerve fiber that releases a chemical message directly to a target organ Chemical signal from endocrine - ANSWER Uses blood to send a hormone to a target organ- slower acting but long lasting. Planaria - ANSWER Movement is the only function of the nervous system in this organism Two lateral nerve cords joined by transverse cords- ladder like - ...

"Kidneys" of arthropods, they absorb ammonium and convert it into uric acid, then into the main gut for rem...

why are planaria so extensively studied? - Answer because they are the most primitive biological group with neural features like brains of the 2 groups in the planaria study the group that was able to turn off the light by intercepting the electric eye - Answer passed the eye more than the other group demonstrating that they learned from consequences if a behavior is started and maintained (strengthened by becoming more likely or more intense) due to a consequence that consequence is c...
