The two types of Cnidarians
What are polyp and medusa?

A parasitic roundworm that is commonly found in dogs (hint: dog owners normally give their pets medication each month to prevent against it)
What are heartworms?

The whip-like structures that keep water moving in and out of sponges.
What are flagella?
400
These worms have a closed circulatory system, much like humans
What are segmented worms?
400
These mollusks have internal shells and multiple appendages. They also move via jet propulsion.
What are cephalopods?
400
The physical differences between insects and arachnids
What are body segments and and legs?
Insects - 3 pairs of legs, 3 body segments
Arachnids - 4 pairs of legs, 2 body segments
