Which organ is the site of gas exchange between the body and the environment?

The Lungs

Explanation:

The lungs and heart are the two organs that work with blood and air, but the lungs maintains the bond between the body and environment. It makes sure that your nose and mouth can take in air from the environment and THEN, to transfer the air from there to your lungs. This helps your body function. Hence, the answer is the lungs.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

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.
