 <span>The teeth and the skin tend to be stained by the action of nicotine and tar. Nicotine is a substance that is extracted from the leaves of tobacco and that can also be produced synthetically; It is a toxic drug that in small doses produces euphoria, decreased appetite, etc., and in high doses can cause serious poisoning.</span>

Nicotine and Tar are the two major components of tobacco that causes teeth staining. Just like our skin, our teeth have pores, which can easily absorb nicotine and tar and turn white teeth yellow. Although nicotine itself is colorless but when it combines with oxygen it turns yellow. Even nicotine infuses electronic cigarettes causes teeth discoloration.  

Most people have dark brown stains on their teeth, it is because of the way they consume tobacco. When tobacco is chewed along with saliva, it produces dark brown liquid which is extremely staining.

<span>Okay, so herbivores are animals that feed on plants, so in Finding Nemo, those would be Bubbles (a yellow tang), the turtles, and Dory (a blue tang). On the other hand, carnivores are all animals that eat meat in order to survive, so in this cartoon, those animals would be primarily the sharks: Chum (a maiko shark), Bruce (a great white shark), and Anchor (a hammerhead shark). </span>

1. Why do you think temperature is the measure of the "average"
Anit [1.1K]

Answer:

Temperature is the measure of the average energy of motion of all the particles present in a substance because particles of a substance moves due to the presence of kinetic energy.

Explanation:

Kinetic energy is a type of energy that is present in an object due to its motion. When temperature of a substance is increased, the particles absorb heat energy from surrounding environment and starts motion. This motion of particles due to the absorption of heat energy is called kinetic energy. So that's why temperature is considered as a tool to measure average energy of a motion.
