Answer:
C- Law of Superposition
Explanation:
The Law of Superposition states that it is logical for older species (for example fossils or rock materials) to support the weight of younger species. This implies that the older species will be at the bottom while the younger will be at the top. Conversely, we can say that the younger species is superimposed on the older ones.
So Layer D is younger than Layer C because D comes after C in the alphabet.
Answer:E. Down-regulation
Explanation:Cells typically up or down regulate depending on the concentration of a hormone levels. When there is a excessive concentration of a hormone in the blood stream, the cell decreases the number of receptors reducing the interaction with that hormone, Also, when there is excessive hormone reduction, the target cells activate to increase their number of receptors.
Down regulation occurs by the the deactivating or degrading of target cells to reduce the number of receptors due to their sensitivity to a particular excess hormone.
