All annelids and arthropods have a body plan. unlike annelids, arthropods also have . the circulatory system of annelids is , while the circulatory system of arthropods is .

All annelids and arthropods have a body plan. Unlike annelids, arthropods also have a coelom, and a segmented body. The circulatory system of annelids is closed, while the circulatory system of arthropods is opened.

Arthropods are invertebrate organism that possess a stiff exoskeleton, a segmented body, and paired jointed appendages. Arthropods include insects, crustaceans, myriapods, and arachnids. Arthropods possess an open circulatory system; a system without blood vessels. The circulatory system of arthropods is made up of a tube (the heart), and an open hemocoel (in which the blood moves).

Annelids are invertebrate animals that have a body cavity, movable bristles, and a segmented body. Annelids include earthworms, and leeches. The circulatory system of annelids is closed; blood circulates through a closed system of blood vessels.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
