A class of students conducted an experiment to determine the effect of exercise on aerobic respiration. They used a solution of bromthymol blue (BTB) to measure carbon dioxide (CO2) production because CO2 causes BTB to turn from blue to yellow. First, they measured how long they needed to blow through a straw into a test tube filled with a BTB solution for the solution to turn from blue to yellow. Then, each student exercised for 2 minutes and measured the time for color change to occur in another test tube. What is the MOST LIKELY result of this experiment?
A
The solution would turn yellow more slowly after exercise.

B
The solution would turn yellow more quickly after exercise.

C
The solution would change color at the same rate before and after exercise.

D
The solution would not turn yellow because CO2 is a reactant of respiration.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

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.
