Chapter 27, Problem 17TYK
Summary Introduction
To determine:
The outcome of the experimentas thought by the researcher and to predict the possible results and to determine the control of the experiment.
Introduction:
Notochord is a rod shaped cartilaginous skeletal structure in all the embryonic and some adult chordates. It has essential functions in the growth and development of vertebrates. It is the primitive beginning of the backbone. Sometimes in embryo it can be seen as a small flexible rod, which is formed from the middle layer of the embryo.
