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.
Molecules: groups of atoms bonded together due to the sharing or donating of electrons Examples: Carbon dioxide, water, NaCl, oxygen. Biological molecules (a.k.a. biomolecules, organic macromolecules, or macromolecules): large molecules that are abundantly found in living organisms and are essential for life.There are four major types of biological molecules.he biological significance of a DNA molecule is that it: 1) Controls the synthesis of proteins (as well as enzymes because they are also proteins). 2) Is responsible for c â¦ arrying hereditary characteristics.
