The image shows a group of birds flying in a v-shaped pattern. which statement is best supported by the image? a. the birds are close together so they have a better chance of finding mates and increasing their reproductive success. b. the birds are part of a eusocial society so they have a better chance of finding mates and increasing their reproductive success. c. the birds are aerodynamically efficient so they can use the air around them to reduce the energy used to fly. d. the birds are part of a eusocial society so they can use the air around them to reduce the energy used to fly.

Option C

Animals moving in packs or flocks, try to utilize the energy efficiently. The same case is with birds moving in V shape. They use the energy of the air around them, so that air pressure could help them fly with less input of energy. V shape pattern is more aerodynamically energy efficient.

Also, while flying there are no chances of finding mates for reproduction, so option A and B are incorrect.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

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.
