Which of the following has two basic body plans?
That's Correct!
It's Wrong!
Invertebrates have two basic body plans: one is the radial symmetry plan (a circular shape arranged around a central mouth), which includes animals who spend their adult lives fastened in one place; and the bilateral symmetry plan (right and left halves that mirror each other). They have a definite front and back end. This includes animals who move in search of food.
On the other hand, vertebrates have the same general body plan with many variations. They have a skeleton, legs and arms of some sort and head.
