ENG 510 Lecture Notes - Maltose, Chromosome, Nitrogenous Base
Document Summary
Organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere. Bacteria prokaryotic, has peptidoglycan, has rrna. Archaea prokaryotic, no peptidoglycan, contained rrna, can live in extreme environments. Explain how electron configuration influences the chemical properties of an atom. The valence (outer shell) electrons want the outer shell to be full. In order to achieve this, they will react to either lose or gain or share electrons. Describe the formation of a hydrogen bond and explain how it differs from a covalent or ionic bond. hydrogen bond: forms when a hydrogen atom covalently bonded to one electronegative atom is attracted to another electronegative atom. Hydrogen bonds are more of a temporary bond. Describe how water contributes to the fitness of the environment that supports all life. Expansion of water contributes to the fitness of the environment for life: prevents deep bodies of water from freezing solid from the bottom up.
