Side chain (of amino acid) the hydrocarbon group on an amino acid represented by H, CH3, or a more complex substituent. (22.6) Sigma (cr) bond a covalent bond in which the electron pair is shared in an area centered on a line running between the atoms.

Do the two grapefruits have the same mass The answer depends on which set of results you consider. Thus a conclusion based on a series of measurements depends on the certainty of those measurements. For this reason, it is important to indicate the uncertainty in any measurement. This is done by always recording the certain digits and the first uncertain digit (the estimated number). These numbers are called the significant figures of a measurement. 

To indicate the precision of a measured number (or result of calculations on measured numbers), we often use the concept of significant figures. Significant figures are those digits in a measured number (or result of a calculation with measured numbers) that include all certain digits plus a final one having some uncertainty. When you measured the rod, you obtained the values 9.12 cm, 9.11 cm, and 9.13 cm. You...
