Between 1932 and 1968, a chemical factory in japan released mercury-laden wastewater into minamata bay. the mercury was modified to methylmercury by bacteria living in bottom sediments. this resulted in severe mercury poisoning in over 2,000 people. since people don't eat bottom sediments, what is the best explanation for how toxic levels of mercury ended up in affected people?

b Mercury accumulated in higher concentrations as it passed through the food chain, resulting in disease in the top-level consumers

Explanation

its correct

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

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.
