The endo-symbiotic theory states that ; one piece of evidence supporting this theory is the fact that
a. the first hereditary material was rna . mitochondria and chloroplasts have heredity based on rna.
b. mitochondria and chloroplasts originated as ingested prokaryotes. mitochondria and chloroplasts have their own dna.
c. the genomes of complex animals came in part from the genomes of invading pathogens . the human genome contains the complete genomes of 120 viruses and 10 bacteria.
d. over time, parasites evolve to resemble their hosts. the dna of human parasites contains segments of human dna.

The correct answer is B.

Explanation:

The answer is partly in the name of the theory. The Endosymbiotic Theory, endo meaning "to absorb" or "to contain" and symbiotic meaning "a mutually relationship between two bodies in which both mutully benefit from" or "close physical interaction between two organisms".

The theory suggests that at some point in time, a prokaryotic cell was consumed by another cell which eventually led to the development of organelles such as mitochondria and chloroplast. The strongest evidence for this statement is the fact that these organelles have their own DNA, which can be an indication to the fact that once they were seperate organisms.

I hope this answer helps.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

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.
