Through the miacles of medicine and technology researchers have had some success with growing and tranplanting hollow, relatinlely simple organs such as tracheas abd bladders. Building organs like the heart heary and lungs have proved to be much more difficult

Explanation:

Simple organs such as the bladder are basically a bag with three entries, this makes these organs easier to create successfully. Other organs such as the heart are much more complex since they contain various Chambers, Valves, Vessels, Walls, and arteries, all of which serve a purpose. Every single part of these organs must be exact in order for it to function correctly, thus making it extremely difficult to recreate. You can see the attached picture of a heart below to get an idea of how complex it actually is.

is this a psat question, if so do not cheat try your best.

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.
