BIO 201- Chapter 1 & 2
Explain how science is a process of inquiry - answer It understand the world by natural
observation. Deductive reasoning- Broad to specific
Inductive reasoning- Specific to broad
List the characteristics common to all living things - answer organized structure
metabolize(use energy)
Grow, reproduce, die
respond to environment
Order the organizational units of life from smallest to largest - answer Atoms, molecules,
cells, tissue, organs, organisms, population, community, ecosystem, biosphere
Recognize the three domains of life – answer Prokaryotes: Bacteria, and Achaea
Eukaryotes: everything else
Explain how the theory of evolution unifies all life on earth - answer common decent:
accounts for unity of life, common ancestor similarities Natural Selection: variation.
Species: a population that can reproduce
Describe the subatomic arrangement of protons, neutrons, and electrons in an atom. -
answerProtons and neutrons are located in the nucleus of a cell, electrons are in
electron shells. Neutrons determine isotopes and mass
Distinguish atomic number, atomic mass, and valence - answerAtomic # is the number
of protons, equal to the number of e-
Atomic Mass- Protons + Neutrons
Valance- electrons in the outer most shell. Atoms with a full shell are complete, atoms
without want to fill it
Classify chemical bonds as either covalent, ionic, or hydrogen and rank their relative
strength - answerCovalent: Sharing of e-, STRONG
Ionic- no sharing, transfer of e-, between oppositely charged ions, Medium strength
Hydrogen- Partial charges, not very strong, effect 3D shape, weak, H0
Distinguish polar from nonpolar covalent bonds - answerpolar: unequal sharing of e-
nonpolar: C-H or 2 of the same atoms, equal sharing of e-
Explain the relationship between the polar nature of water and its ability to form
hydrogen bonds. - answerCohesion: attraction between water molecules by H+ bond
Adhesion: attraction of different molecules by polar H+ bonding
