Sound waves are both compressional and longitudinal, (although we frequently draw them as transverse waves).

Longitudinal waves are where the particles of matter collide into one another, pushing them into the next and then oscillating back. This is how sound travels. This is also why sound can only travel through a medium, it cannot travel through a vacuum, as is shown here:

An energy-transferring compound in cells is a nucleotide known as
8090 [49]

Adenosine triphosphate (ATP) is a complex molecule which provides energy to the cells. This molecule is present in all the living organisms. The chemical energy which is obtained by the body by the breakdown of the food is captured by the ATP (Adenosine Triphosphate) molecules. This captured chemical energy is then transferred by it in order to fuel different body processes.

Hence, the answer is ATP (Adenosine Triphosphate).

How many calories are provided by a food that contains 29 grams of carbohydrate, 6 grams of protein, and 1 gram of fat?
Andrej [43]
Energy (caloric) value of foods is indicated by calories, which measure the amount of heat that the food releases in the metabolic process. In physiology, it is determined by the energy balance of the organism, ie the heat exchange between the organism and the external environment.
Calories of nutrients:
1 g of protein = 4 kcal (kilocalories)
1 g of fat = 9 kcal
1 g of carbohydrates = 4 kcal
1 g of alcohol = 7 kcal
1 g of organic acid = 3 kcal

According to the table above, we can calculate required value:

29x4 + 6x4  + 1x9= 149 kcal/g

Air is a mixture of many gases, primarily nitrogen, oxygen, and argon. Could distillation be used to separate air into its compo
vladimir2022 [97]
Yes. Air can be separated through fractional distillation. The air must be cooled to a liquid first. Considering nitrogen oxygen and argon all have different boiling points, the liquid air mixture can be heated very gently and carefully in a fractionating column. Each element will eventually vaporise and they can be condensed and collected at different points up the fractionating column because they each have different boiling points.

Which describes the complex carbohydrate cellulose?
FromTheMoon [43]
Like starch, cellulose is a complex carbohydrate made up of many molecules of glucose linked together. But unlike starch, plants do not use cellulose to store energy. Instead, plants use cellulose as a structural molecule. It forms the cell wall that gives plant cells shape and support.
