LIFE 102 Study Guide - Final Guide: Covalent Bond, Hydrogen Bond, Methyl Group
Document Summary
Emergent properties are the arrangement and interactions of parts as complexity increases. Cilia cells are identical even when in 2 different area of the body. Carbon, hydrogen, nitrogen and oxygen make up 96% of living matter. The atomic number is the number of protons in a cell. The mass number is the sum of protons and neutrons in a cell. A covalent chemical bond is one where the outer shell electrons of 2 atoms are shared so as to fill their respective valence shells.

Partially negative charge in water molecules occurs because the electrons shared between the o2 and h atoms spend more time around oxygen nucleus than around the h nucleus. 1 mole of glucose solution (c6h12o6) contains 6. 02 x 10^23 glucose molecules. H20: the oxygen molecule is negatively charged while hydrogen is positively charged. An aqueous solution is when the solute is being dissolved by water.
