For the following question, match the key event of meiosis with the stages listed below.
i. prophase i v. prophase ii
ii. metaphase i vi. metaphase ii
iii. anaphase i vii. anaphase ii
iv. telophase i viii. telophase ii
synaptonemal complexes form or are still present.
a)i only
b)i and iv only
c)i, ii, iii, and iv only
d)i and viii only
e)ii and vi only

A)I only

Explanation:

The synaptonemal complex is formed during the prophase 1 of meiosis. The synaptonemal complex is a s a protein structure that is formed between the homologous chromosomes that form a bivalent.  This structure binds and holds homologous chromosomes together and allows crossing over and genetic recombination between them. Crossing over and recombination occur in prophase 1, therefore, the synaptonemal complex disintegrates before the end of prophase 1.

why do you want to cheat? i dont take it, so i dont know.

explanation:

some tips: get a tutor

study

ask for

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.
