Chapter 1
• Scientific Method• Theory, law• Scientific Experimentation ( variable, control, IV,
DV, constants)• Major Contributing Theories: • 1.The Cell Theory,• 2. Evolution by Natural Selection, (all 4 pts)• 3.Gene Theory, • 4. Homeostasis
Names to know
• Cell Theory: Hooke, Schleiden and Schwaan (1800s)
• Gene Theory: Watson, Crick (1953)
• Evolution: Darwin, Linneus, Lamark, Wallace
3 domains, 5 kingdom system
• Domains: Archae, Bacteria, Eukaryota• Kingdoms: Archaebacteria – extreme• Bacteria(Monera) – single celled,
prokaryotic• Protista – simple eukaryotic cells• Fungi – mostly multicellular decomposers• Planatae – multicellular producers• Animalia – multicellular heterotrophs
Characteristics of Living Things
• 1) Organization• 2) Homeostasis• 3) Adapt to Environment• 4)Reproduction and Heredity• 5)Growth and Development• 6) Energy Acquisition and Release• 7) Detection and Response to Stimuli• 8 ) Interactions
Levels of Organization
• Biosphere to subatomic Particles ( be able to put in order)
Ch2 Chemistry Review
Matter ( anything that has mass and takes up space)
1. Mixture
2. Pure Substance
a. Element
b. compound
Basic unit of matter is the atom
Subatomic units: proton, neutron and electron
Isotopes
• Same element, different mass.
• Different # of neutrons
• Ex C-14
• Atomic #
• Atomic Mass
Periodic Table and Energy
• **don’t need to know all the orbital info
• Basics of periodic table
• Einstein and the electron ( E=mc2)
• Electrons in their excited state
Bonding
• 1. Ionic
• 2. Covalent ( double, triple)
• 3. Hydrogen
Chemical Reactions and Bonding
• Molecules – covalently bonded compounds. Fixed ration
• Glucose =C6H12O6
• Reactants Products– (synthesis – combination, dissociation –
decomposition)– CHON
Ch3: Water
• Many of it’s unique properties can be contributed to the fact that it is polar.
• “Universal solvent”
• Solutions ( homogeneous mixture)
• Like dissolves like ( oil and water)
Acids and Bases
• Acids – dissociate into H+ ions
• Bases – dissociate into OH- ions
• pure water is =
• pH scale (0-14) – hydronium concentration
Organic Molecules
• 1) formed w/ actions of living things
• 2)have a Carbon backbone
Then just the basics…
• What is a functional group: We will study them in more detail in Ch4
• 4 types of Macromolecules ( more detail in Ch5) and example– Carbohydrates– Lipids– Amino Acids– Nucleic Acids
