Question

A bilaterally symmetrical animal can be divided into two equal halves by:

• A. A diagonal cut.
• B. Any cut from its dorsal to its ventral surface
• C. A cut through the midline of its body from its anterior to its posterior end
• D. A cut through the midline of its body from its dorsal to its ventral surface

Answer 1

Answer: (C)

A cut through the midline of its body from its anterior to its posterior end

Many animals are bilaterally symmetrical, which means they can be divided into mirror images (left and right) by a single plane that passes through the midline of its body. This plane runs from the tip or the anterior end of the body to its tail or the posterior end. For example, the beetle is bilaterally symmetrical.
Thus, the correct answer is option C.
