A researcher performed an analysis of the elemental composition of several fish species living in the same body of water. The amount (in parts per million) of iron (Fe), calcium (Ca), potassium (K), sodium (Na), and magnesium (Mg) found in each species is shown in the table. Species Fe Ca K Na Mg Species A 55.70 179.51 107.94 45.39 33.89
Species B 23.74 134.16 105.19 45.10 33.38
Species C 67.18 785.18 103.60 42.71 32.45
Species D 30.09 457.59 107.97 44.68 33.84
Based on this data, identify which elements are found in similar concentrations across all species of fish tested. Explain how this data provides support for the hypothesis that all four species of fish descended from a common ancestor.

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.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.
