Biology Exam 1 Guide
Students MUST know and understand: – The core concepts of the course (STEMS) and how they are applied
– The steps involved in the scientific method, scientific laws and scientific theories
– Steps involved with gathering and analyzing data and forming and testing hypotheses
– Characteristics of living organisms and the levels of organization of organisms (from
atoms to biosphere)
– The features of credible sources
– Levels of organizations of matter and living organisms
– The three domains of life
– Atomic structures, elements and compounds, electron distribution and electron orbitals
– Formation and function of molecules and ionic compounds depend on chemical bonding
between atoms. Describes what happens and what are the results of ionic bonds,
covalent bonds (polar and nonpolar), and hydrogen bonds.Biology Exam 1 Guide
– What chemical bonds are and identify the general components of them
– The properties of water
– Hydrophilic vs. hydrophobic substances
– Acids vs bases and how those conditions affect living organisms
– The pH Scale and buffers
– Carbon and the biomolecules (structure function sources hydrophobic/hydrophilic)
