The Law of Superposition.
The Law of Superposition states that each layer is younger than the one beneath it.
If an individual has an <u>increased</u> rate of blood flow to the skin,such as would happen with emotion or alcohol consumption ,their skin takes on a <u>reddish</u> tinge.
Explanation:
Our skin is provided with a large number of blood capillaries. These capillaries bring blood and nutrients to the layers of skin. Whenever vasodilation of these capillaries occur, the blood flow to the skin increases and the skin gets a reddish tinge.
During an emotional upsurge such as embarrassment causes the adrenal glands to release adrenaline.
Adrenaline as well as alcohol vasodilates the blood vessels and increases the flow of blood to the skin. Hence, the skin gets a reddish tinge.
<span>Organisms all possess DNA as their genetic material. What differentiates them (and their DNA) is the sequence of base-pairs within the DNA. The base-pairs are actually specific sequences of nucleotides (i.e. adenine , thymine, guanine and cytosine, labelled A, T, G, and C respectively) which encode genes. In other words, the DNA in each organism is made of these bases, but their sequences differ from organism to organism.</span>
