Which mechanism is responsible for reductional cell division?
a) mitosis
b) cancer
c) meiosis
d) budding
d) none of the above

Meiosis.

Explanation:

Meiosis may be defined as the process of cell division in which a single parent cell divides into four daughter cells. This type of division occurs in the sex cells.

The meiosis division is also known as reduction division because the daughter cells contain the half number of chromosomes as compared with parent cell. The meiosis is divided into meiosis-I and meiosis-II.

Thus, the correct answer is option (C).

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.
