Biomolecules have a wide range of sizes and structures and perform a vast array of functions. A liquid takes the shape of its container. What exercises should be avoided with iliotibial band IT band syndrome? For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl, whereas water is always made from twice the number of hydrogen atoms as oxygen atoms, so it is H. An impure substance made from different elements or compounds mixed together that are not chemically joined. See how far you can make the drop hang off the end of the dropper without the drop falling. These polymers are composed of different monomers and serve different functions. An example of a natural polymer is rubber. Measure a certain volume for an amount of liquid in a measuring cylinder.
