Biol101 fall 2015 higgins: exam i study guide topics covered on exam i: Science: steps of the scientific method, what is science", difference between hypothesis vs. theory, biology domains of life, characteristics of living things. Living properties [reproduce, cellular-homeostasis (unstable), energy-metabolism (tear apart and build), dna and/or rna] Physics and chemistry: know parts of an atom. Valence electrons outer shell (first=2, second=8) determines number of bonds [seeking stability] Polar = positive or negative charge (reacts with water) hydrophilic, soluble. Nonpolar = no charge (repelled from water) hydrophobic, insoluble. H2o = hydrogen slightly positive charge, oxygen slightly negative charge. Biomolecules: what is an element, what causes atoms to bond, types of chemical bonds between atoms and relative strength, water properties. Biological molecules: carbohydrates, proteins, nucleic acids, lipids. Dna, plasma membrane, capsule, cell wall, ribosomes, cytoplasm, bacterial flagellum. Many types of organelles: cell organelles, animal cell, plant cell.
