Which statement about bilaterally symmetrical animals is true?

Question

Quizplus · Accepted Answer

Bilaterally symmetrical animals have a distinct dorsal (back) and ventral (underside) surface, and can be divided into two similar halves only by a plane at right angles to the midline. The anterior (head end) and posterior (tail end) are also clearly defined. Option A is incorrect because not every plane that cuts through the center will produce similar halves. Option C is partially correct, but it lacks the specification that only a plane at right angles to the midline can produce similar halves. Option D is incorrect because not all body parts are equally capable of leading movement in all directions.
