Moonlight is up to 400,000 times dimmer than sunlight, and its reflected light contains a negligible amount of the specific UVB radiation required for your body to produce vitamin D. This definitively answers the question of how much vitamin D do you get from the moon: none at all.

In laboratory extractions, ethanol is effectively used to help remove fat, showcasing its ability to interact with and dissolve lipids. This capability, however, depends heavily on the context, as the same principle works for removing grease stains but not for burning body fat. Understanding how and why ethanol removes fat is crucial for both practical cleaning applications and for grasping its biological effects.

The human body is highly efficient at absorbing oxygen, relying primarily on the lungs for this vital process. This raises a key question: **can humans drink oxygenated water** to gain additional health benefits beyond normal hydration, or is it just a marketing gimmick?

Studies from educational resources confirm that a commercial sports drink possesses a uniform composition throughout, with its various components evenly distributed. This uniformity is why a sports drink is classified as a homogeneous mixture and not a compound, which requires a fixed chemical formula.

According to the NHS, an average man needs 2,500 kcal per day, while an average woman needs 2,000 kcal to maintain their weight. This is just one example of the common use of the term in a nutritional context, but is energy also known as calories? The relationship is much more nuanced and depends heavily on whether the term is being used in a scientific or dietary context.

While standard tap water typically has a neutral pH of 7, the concept of a significantly higher pH level is becoming popular. So, what water has a pH of 10, and what does it take to achieve this highly alkaline state for drinking purposes?

The average serving of Mexican mole sauce can contain hundreds of calories, yet the chemical unit known as a mole has zero. This classic science riddle, 'how many calories are in a mole,' plays on the different meanings of the word and has no single correct answer without clarification.
