Answer:
The correct answer is B. Prokaryotic cell consumed a smaller cell.
Explanation:
Endosymbiosis theory says that the origin of eukaryotic cell happens when a bigger prokaryotic cell consumer a smaller prokaryotic cell but the bigger cell did not consume the smaller cell rather these two cells remain in symbiotic association with each and later evolved as a eukaryotic cell.
The evidence of this theory can be seen in eukaryotic cells in the form of mitochondria and chloroplast in animal and plant cells. These two organelles are very closely related to today's prokaryotic cells.
Both the organelles have their own circular genome enclosed in double membranous structure and 70s ribosomes which resembles the bacterial cell. Therefore, the correct answer is B. Prokaryotic cell consumed a smaller cell.
There is no picture shown, however details like this indicate that Scientist are examining the future changes in biodiversity within the Hudson river. If vegetation would see a continuous decrease, animals are forced to flee their habitat and find new areas or locations where they could thrive. When this happens, changes in the environment would put a great deal on the existence of certain forms of species within the area.
I think A would be the answer
Typical cervical vertebrae have several features distinct from those typical of thoracic or lumbar vertebrae. The most notable distinction is the presence of one foramen, in each transverse process. These transverse foramina encircle the vertebral arteries and veins.
