Eukaryotic, Dueterostome development
Vertebral column, True tissues
You are given an embryo with eight cells and you carefully separate them and allow them to develop in separate containers. Each of the cells forms a complete embryo that develops normally into an adult animal. How would you categorize your animal?
It is a protostome.
It has determinate cleavage.
It has spiral cleavage.
It is an annelid, mollusk, or arthropod.
It has indeterminate cleavage.
explain the evolution of life. Comparison and description of the early organism and relate their characteristics with their environment.
