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.

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
