Glycerol is a type of alcohol. There are many different liquids such as; water, oil, fruit juice, and many others. They are involved in building organisms from single cells to complex living beings like humans, by interacting with each other. Therefore, denisty (kg/m) = mass (kg) / volume (m) Measure the density of solids: Weigh the object using a scale. 0.0 / 5. Definition: A biomolecule is a chemical compound found in living organisms. The kinetic theory is an attempt to explain why materials occur in three different forms, or states. The particles of a liquid are attracted to one another, are in motion, and are able to move past one another. Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). Tape the Race Drop Raceway sheet onto a piece of cardboard to give it support. The particles in solids, liquids and gases are arranged differently and move in different ways. Does water have mass, and does it take up space? Biomolecules are vital for life as it aids organisms to grow, sustain, and reproduce.
