Use the principle of original horizontality to identify the two rocks that are nearly the same age.
Digiron [165]

The correct answer is - C and D.

The principle of original horizontality means that the rock layers have been order by age, with the layers at the top being the youngest, while the layers at the bottom being the oldest.

In this picture it is little hard to tell which rocks belong to the same layer from first look because there are multiple twists and turns, an uneven surface, caused by pressure on the crust.

By carefully examining the image though, we can trace the layers more properly and see which ones are younger, which older, and which have the same relative age. In this case, we can see that the markings C and D are actually on the same layer of rocks, thus being a good indication that they have the same relative age.

lozanna [386]

Answer:

Option A, hydrophilic/hydrophobic forces

Due to this structural complexity, phospholipids produces barrier both at the interior and exterior of cell and hence form a membrane bilayer under suitable conditions. For instance when it is in water, it arrange itself in a way that their hydrophobic tails lie at the inner side and hydrophilic heads face outer side.  

Hence, option A is correct
