This is because some of the things that existed were eaten by other things and so ceased to exist.

What is the difference between linear and non linear graphs?

Linear graphs make straight lines. Non-linear graphs make thins like parabolas, hyperbolas, and ellipses.

How many lines are in a cinquain?

There are 5 lines in a cinquain. 1st line: 1 word title (noun), 2nd line: 2 descriptive words (adjectives), 3rd line: 3 words that express action, 4th line: 2 words that express feeling, last line: 1 word (synonyms or reference to title in line 1)! Hope thins works! :)


How can there be a correlation between two things even though one does not cause the other?

Let's say we look at the consumption of junk food and heart attacks. What we would see is a correlation. The more junk food you eat the less risk of a heart attack. There is a correlation but is there a cause and effect relationship? Probably not. Young people eat a lot more junk food than older people. And older people are much more likely to suffer from a heart attack. Mathematically this is due to correlation between your x variables. In statistical analysis you usually assume independent variables. In reality thins are much more complicated. If you want to establish true relationships you need to use design of experiments (DoE).


What exactly are the snots?

Simply put, snot is mucus that is produced by a special membrane in the nose. The purpose of snot is to trap dust particles, germs and pollen that are inhaled and to prevent them from getting into the lungs. When the inhaled particle and the surrounding mucus that surrounds it dry and solidify, you get what most people call bogeys (or boogers in the USA). Runny noses and copious amounts of snot can be particularly bothersome during the winter. Ailments such as the common cold can lead to increased nasal mucus production but even those in good health can find themselves sniffing and snotting when they walk from the cold outside air into a well heated room. This is because mucus will thicken outside in the cold, but in a heated room the mucus thins and becomes runny. A particularly charming thought to finish on: we actually produce a cupful of nasal mucus every day and much of it ends up getting swallowed!!!!
