8. Which of the following involves a situation in which a density-dependent factor influences a population?
a. Several seasons passed during which rainfall was ample, winters were not severe and
food for snow hares was in good supply.
b. A hurricane severely disrupted a salt marsh and uprooted most of the marsh grass in an
estuary.
c. A forest fire on the north side of a mountain forced the white-tailed deer from the north
side to move into the range of the white-tailed deer on the south side of the mountain,
making food more scarce.
d. After a heavy rain, pesticides that were applied to a cotton crop to control weevils ran off
into a waterway that flows next to a field.

pine trees. Which population has the highest density?
a. white-tailed deer
c. armadillos
b. coyotes
d. Toblolly pine trees

Which of the following involves a situation in which a density-dependent factor influences a population?

A forest fire on the north side of a mountain forced the white-tailed deer from the north  side to move into the range of the white-tailed deer on the south side of the mountain,  making food more scarce

Explanation:

the correct option is option d

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.
