As an undergraduate research assistant, you are assisting with a radioisotope tracer experiment. You expose a mature leaf on one side of the lower shoot of a sugar beet plant to 14CO2 and then track the movement of the 14C atoms by radiography. Where are you LEAST likely to detect 14C?

a. the roots
b. the treated leaf
c. a mature upper leaf on the opposite side of the plant from the treated leaf
d. the shoot apical meristem

Explanation:  

C-14 is an isotope of Carbon that is radioactive in nature and used for various purposes in the research and some other fields.

It is used in carbon dating, carbon labeling, and some other way.

As carbon labeling, it has may important in the detection of biochemical reactions.

Since the mature upper leaf part are away from the treated parts so the least amount of C14 is detected in such a portion.

there really is life in the deepest part

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.
