+ Alcoholism: Diseases :: Psychology
  * The biological mechanisms that cause alcoholism are not well understood. Social environment, stress, mental health, family history, age, ethnic group, and gender all influence the risk for the condition. Consuming large amounts of alcohol produces changes in the brain's structure and chemistry. Some changes occur very early, even when small amountas of alcohol are consumed, in a short time. Examples are tolerance and physical dependence. Because of the changes, it is very difficult for an alcoholic to stop drinking, as this would result in alcohol withdrawal syndrome if the person stops. Alcohol damages almost every organ in the body, including the brain. Chronic alcohol abuse can cause both medical and psychiatric problems.

By breaking the chemical bonds in carbohydrates, energy is released and can be used by the body.

  * A 'dress code' is a rule about what people should wear. For example, when walking around a city or going to work one needs to have appropriate clothes. These can change depending on different countries and cultures. Some private places might also have a dress code that people need to follow to be allowed in. Examples are churches and nightclubs.
+ Food group, Common food groups: Nutrition
  * Sweets is many times a very small group in nutrition guides, and sometimes this group is not included or is put apart from other food groups. Some examples are candy, soft drinks, cake, pie and ice cream.
+ Fracture (geology): Geology
  * In geology, a 'fracture' is any kind of separation or break in a rock formation. Examples are joints or faults. These divides the rock into two or more pieces. 6 A fracture can sometimes form a deep, wide crack in the rock. They are usually caused when the rock is not strong enough to hold up under too much stress. This makes the rock crack along its weakest point.
  * Examples help illustrate a point.

Detecting an unhealthy intruder is complicated, because intruders can evolve and adapt so that the immune system will no longer detect them.

He explains how evolution has left its traces on the characteristics which are the specialty of the human species. Examples are generosity, self-sacrifice, worship and the use of sex for pleasure.
+ Pain, Treatments for pain:
  * These medicines decrease the inflammation where the person is hurt. They also work in the brain to decrease pain. Examples are aspirin, ibuprofen, and naproxen. These medicines can make someone sleepy but they are not addictive. They can cause problems with kidneys and with peptic ulcers.
  * Other pain medicines may not work at all for those kinds of pain. Examples are carbamazepine and gabapentin.
+ Poison gas: Weapons :: Chemical warfare
+ Red Dead Redemption, Gameplay: 2010 video games :: PlayStation 3 games :: Xbox 360 games

Players can also take part in many events they come across as they explore the world. Some examples are public hangings, ambushes, cries for help, and animal attacks. Players can also take part in optional side activities ranging from standoffs, five fingers fillet game, gambling, and hunting animals for pelts and meat.
+ Shelf life, Temperature control: Foods
  * Examples are the breakdown of many chemical explosives into more unstable compounds. Nitroglycerine is notorious.
+ Still: Tools
  * It does this by first boiling the liquid and turning it into a gas. This gas is then cooled, changing it back into liquid. Stills get their name from the word di'still'ation. Distillation is the process of boiling and cooling a liquid to purify it. Stills are most often used to create alcohol, but they can also be used with any liquid. Some examples are medicines and perfumes.
+ Telluride: Tellurium compounds
  * Telluride' is an ion. Chemical compounds containing this ion are called 'tellurides'. Examples are sodium telluride and hydrogen telluride. Tellurides are strong reducing agents. Some tellurides are impure, making them weaker reducing agents. Tellurides are the main source of tellurium in the ground. It only exists at very high pH. At lower pH's, hydrogen telluride, HTe-, is made.
  * Examples are included on the talk page.

  * A 'side-effect' is an unwanted effect from therapy. For example, taking medications as tablets or injections may cause many sorts of side-effects. Examples are headaches, nausea, rash, constipation, blurred vision and others. Radiotherapy can also cause side effects of nausea, rash on the skin, and vomiting, for example.
+ Tiger, Prey
  * Tigers eat many different types of prey, mostly other large mammals. Some examples are deer, monkeys, wild pigs, tapirs and other animals found in Asia. Some tigers may eat up to  of meat a day. Tigers kill their prey by clamping down on the prey's throat and suffocating it.

  * The rules are named after Robert Burns Woodward. He was a Harvard University chemistry professor who won the Nobel Prize in chemistry. The rules are sometimes called the 'Woodward-Fieser rules', to also honor Louis Fieser. The rules build the prediction on the type of chromophores present, the substituents on the chromophores, and changes due to the solvent. Examples are conjugated carbonyl compounds conjugated dienes, and polyenes.
+ Writing, History of writing, Ancient Egypt: History of technology
  * The two cursive scripts were written with reed pens and carbon inks onto papyrus, also by brush onto cloth. Many examples survive. The hieroglyphs were carved into stone or painted onto stone surfaces. Many survive, some with the original colours intact. The key event in the decipherment of hieroglyphic writing was the discovery of the Rosetta Stone. This is a granite slab with the same message written in hieroglyphic, demotic and in Greek. Ancient Greek is well understood, and made possible the interpretation of the other two scripts.
  * More examples are given in the test cases.
