Which of the following statements regarding endosymbiotic theory in the evolution of eukaryotes is supported by the data in the
chart? A
The structures and functions of mitochondria and chloroplasts, organelles found in eukaryotic cells, are similar to those of prokaryotic organisms. This, combined with when each of these first appeared on Earth, supports the theory that eukaryotes came from larger prokaryotes engulfing smaller prokaryotes.
B
Eukaryotic organisms contain many linear chromosomes in their cells. Their cells replicate using mitosis. Scientists estimate that eukaryotes appeared on Earth around 1.5 billion years ago, long after the first prokaryotes appeared. Eukaryotes are very complex, while prokaryotes are simple bacteria.
C
Scientists found that prokaryotic organisms were on Earth much earlier than eukaryotic organisms. Over time, prokaryotes became eukaryotes that were able to make their own energy in their mitochondria. Some eukaryotes developed chloroplasts that allowed them to make their own food using photosynthesis.
D
Eukaryotes are very different from prokaryotes. Prokaryotes are similar to mitochondria and chloroplasts, because they all undergo binary fission and have circular DNA. Eukaryotes could have evolved from prokaryotes, since prokaryotes have been on Earth for a longer period of time.
Complete digestion of food takes place in the intestine. Various enzymes present in the intestine act on food and digested food gets absorbed. Typhlosole increases the absorption surface of the intestine.13
The longmenshan fault is in china. This fault was created when two tectonic plates collided with each other, resulting in the rise of mountains next to the sichuan basin. This fault is most likely a reverse fault.
A reverse fault is a fault that exists in areas that are undergoing compression in which the rock on top of the fault plane is moved upward relative to the rock under the fault plane. A reverse fault is completely different from normal faults and it reduces the faulted section of rock.
