Polyphenisms correct answers Discontinuous phenotypes that are elicited by the environment. Multiple ways an organism can develop due to the effects of its environment during development. Theme of polyphenism correct answers The endocrine system will meduate which of the phenotypes develop. Sensory organs send a nuerological signal back to the brain to change the events of development. Endocrine system is a testimony to the different hormones that are present. Signaling from sensory organs to...

Describe the basic embryological process behind development of the neural tube - Answer-- the* notochord* induces overlying ectoderm to differentiate into neuroectoderm and form the neural plate (day 18) - the neural plate invaginates to form the *neural tube* and at the same time, cells demarginated from the invaginating tube to form the *neural crest cells* What are the basal and alar plates? What do they give rise to? - Answer-The alar and basal plates are basically the dorsal and vent...
