Porifera are one major phylum of invertebrates. Porifera are commonly called sponges. They have porous bodies without any organs. In fact, they are very simple organisms. They don’t even have mouths. Sponges live in water, which they filter through their bodies. That’s how they capture food. Sponges’ bodies are asymmetric. That means that they don’t have symmetry. No two halves of their bodies line up. Sponges’ porous bodies help them to (what?)

a. make food from the sun.
b. poison their prey.
c. capture food.
d. reproduce.

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
