The DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers. Each nucleotide consists of the pentose sugar deoxyribose, a phosphate group and a nitrogenous base which may be either a purine or a pyrimidine. Deoxyribose and a nitrogenous base together form a nucleoside.he DNA molecule is a polymer consisting of several thousand pairs of nucleotide monomers.

One way to measure the temperature of matter is. to place a thermometer in contact with it. Some of the. matterâs kinetic energy is transferred to the thermometer. if the matter is warmer than the thermometer. The. increased kinetic energy causes the particles of the. liquid in the thermometer to move farther away from. each other.
A thermometer is any device used to measure temperature, consisting of a temperature sensor and some type of calibrated scale or readout device. Liquid-in-glass thermometers and thermistor thermometers are most commonly used to measure air and water temperature.
