Which of the following occurs when the plant needs co2 for photosynthesis? guard cells open by releasing solutes from their cytoplasm out of the cell, causing h20 to diffuse out of the cells by osmosis guard cells close by releasing solutes from their cytoplasm out of the cell, causing h20 to diffuse out of the cells by osmosis guard cells open by pumping solutes into their cytoplasm, causing h20 to diffuse into the cell via osmosis guard cells close by pumping solutes into their cytoplasm, causing h20 to diffuse into the cell via osmosis

i think b... not positive, sorry if its wrong!

"do a testcross with a homozygous recessive plant."

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.
