Question

multiple choice question
a gastrovascular cavity occurs in animals with a(n)
o incomplete digestive tract.
o deuterostome pattern of development.
o asymmetrical body plan.
o segmented body.

Explanation:

A gastrovascular cavity is a central cavity with a single opening that functions in both digestion and circulation. Animals with an incomplete digestive tract have a single opening (mouth/anus). Deuterostome pattern of development is about embryonic development (not related to gastrovascular cavity). Asymmetrical body plan is about body symmetry (not related to cavity function). Segmented body is about body segmentation (not related to cavity function).

Answer:

incomplete digestive tract.
