The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because <span>the observed changes in histone modifications are consistent with reduced transcription.</span>

Onion skin is a plant cell. And your skin cell is a animal cell.
Basically as simple all the structures in animal cell can be found in plant cells. But plant cells has some extra structure and part where doesn't exist in animal cells.
In animal cell, it contains a cytoplasm, nucleus and a cell membrane.
But in plant cell, they have chloroplast, cell wall and vacuole in additional.
Plate tectonics is referred to a geology theory, which explains the movement of earth’s lithosphere. This theory suggests that the earth’s lithosphere is made up of many plates, and these plates move on each other causing collision of the plates or sometimes separation of the landmasses.
Sometimes, the movements of the plate occur in such a way that the surface of the earth is buried underground. Even in normal circumstance, some of the surface materials buried underground. So, by studying the type of things existed on the surface in past, one can predict the abundance of a specific substance underground.
Hence, the correct answer is option b. – Plate tectonics.
