The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
Peptide Bond. Covalent bond between the nitrogen of the amino group of one amino acid and the carbon of the carboxyl group of a second amino acid, joining the 2 amino acids together in a peptide or protein.
1 1 Chemistry of Life-Part 2Biological Molecules 2 Of the 92 naturally occurring elements, 16 are known to be important constituents of living systems.The important elements are C, H, O, N, P, S. 2 3 All important biological molecules contain carbonAll molecules that contain carbon are called organic (except for CO 2). All other molecules are _________.Carbon forms 4 covalent bonds. This allows carbon to form molecules with many different shapes. 4 Most biological molecules have a core made of carbon and hydrogen. Molecules differ in structure and function, in part, because of different functional groups.
