air pressure: Force exerted by the weight of air molecules.
blue whale: A type of baleen whale (glans muscle) It is the largest animal known to have ever existed. It can grow up to 30 meters (almost 100 feet) long and weigh up to 170 tons.
calorie: The amount of energy required to raise the temperature of 1 gram of water by 1°C. It is typically used as a measure of the energy contained in a given amount of food. Exception: When referring to the energy of food, the convention is to refer to 1 kilocalorie, or its 1,000 calories, as a “calorie.” Here, food calories are the amount of energy required to raise the temperature of 1 kg of water by 1°C.
carbohydrates: A general term for many compounds that exist in food and biological tissues, such as sugars, starches, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and are normally broken down in the animal's body to release energy.
chemistry: The field of science that deals with the composition, structure, and properties of matter and how they interact. Scientists use this knowledge to study unknown materials, reproduce useful materials in large quantities, and design and create new and useful materials. (of compounds) Chemistry is also used as a term to refer to a recipe for a compound, a method for making it, or some of its properties. People who work in this field are known as chemists.
fat: A natural oily or greasy substance found in the bodies of plants and animals, especially in layers deposited under the skin and around certain organs. The main role of fat is to store energy. Fat is also an important nutrient, but too much can be harmful.
Joule: The amount of energy required to generate 1 watt per second. Joule is a standard unit of energy.
nutrition: (adjective, nutritious) Healthy ingredients (nutrients) in the diet, such as proteins, fats, vitamins, and minerals, that the body uses to grow and provide energy for its processes. Scientists working in this field are known as nutritionists.
protein: A compound made from a long chain of one or more amino acids. Proteins are an essential part of all living organisms. They form the basis of living cells, muscles, and tissues. They also work inside cells. Antibodies, hemoglobin, and enzymes are all examples of proteins. Drugs often work by adsorbing to proteins.
sea ​​level: The total height of the Earth's oceans when all tidal and other short-term changes are averaged.
unit: (in measurement) A unit of measurement is a standard way of expressing a physical quantity. Units of measurement provide context for what the number represents and convey the magnitude of a physical property. Examples include inches, kilograms, ohms, gauss, decibels, kelvins, and nanoseconds.
whale: A common but rather imprecise term for a type of large marine mammal. This group includes dolphins and dolphins.
