4. A marine biologist exploring a deep sea trench locates a new species of soft-bodied creature with an unfamiliar shape. He is able to determine that the creature is a mollusk because it has (1 point) bilateral symmetry. body segmentation. an internal shell. an internal skeleton.

Thanks Alot , I Got Them All Right ! (: 1. Few fossils of the earliest animals exist because they (1 point) (0 pts) had hard shells that broke down easily, leaving no trace. (0 pts) were large and likely to be eaten by others after they died. (1 pt) were soft-bodied and tiny, therefore, unlikely to fossilize. (0 pts) lived only in volcanic regions, and were destroyed by lava flows. 1 /1 point 2. Some of the fossils that have been found from before the Cambrian Explosion are embryos. This suggests that the organisms these fossils belong to (1 point) (0 pts) have bilateral symmetry. (0 pts) reproduce asexually. (0 pts) exhibit cephalization. (1 pt) reproduce sexually. 1 /1 point 3. Most of the body features found in invertebrates evolved during which of the following periods? (1 point) (0 pts) Jurassic (1 pt) Cambrian (0 pts) Cretaceous (0 pts) Permian 1 /1 point 4.
