Segmented worms have their body in segments, making them stronger for digging.Segmented worms have the first true brain.

Question 19

setae def

Answer 19

Setae are bristles used for movement and protection

Question 20

Mollusks have a ganglion or brain, making them very intelligent.A mantle is a body tissue that makes a shell. Mollusks are the first and only animals to have shells, which are hard secretions for protection and body support.

Question 21

What are the characteristics of echinoderms?

Answer 21

Echinoderms have radial symmetry.Echinoderms are the first animals to have an endoskeleton, which is an internal skeleton.Echinoderms are the first animals to have an endoskeleton, which is an internal skeleton.

Question 22

What are the characteristics of arthropods?

Answer 22

Arthropods have bodies in segments with complex jointed parts like legs, antennae, mouth parts, and wings Arthropods have an exoskeleton, an external skeleton made of chitin. Metamorphosis is the process of changing from a larva into a mature sexual adult.
