The "steady state" or constant condition maintained by the body is called and is necessary for life.

The correct answer for the fill in the blank is Homeostasis.

Homeostasis can be defined as the ability of an organism to keep its internal body conditions as constant. In other words, when a steady state or constant environmental condition is maintained by a body, it is called Homeostasis.

For instance, the body temperature of human beings is . This is maintainted constant due to homeostasis.

Homeostasis is necessary for life as it allows the body to remain healthy with the steady state.

Example- Enzymes, which are very crucial for any biochemical process, require optimum conditions ( temperature, pH) to work efficiently. This is maintained through homeostasis.

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.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
