HESI Biology EvolveTaxonomy: The three domains - ANS Archae, Bacteria, and Eukarya
Natural Selection - ANS theory by darwin: traits that help give a species survival advantage are
passed to subsequent generations
Gradualism - ANS evolution proceeds at a steady pace
Punctuated equilibrium - ANS evolution involves long time periods of no change (stasis)
Scientific Knowledge - ANS sum of all scientific inquiries for truths about the natural world
carried out throughout history
Scientific Method - ANS 1. identify a problem or pose question
2. Hypothesis
3. experiment
4. observe results
5. conclusions
Important properties of water - ANS 1. high polarity
2. hydrogen bonding
3. cohesive, adhesive
4. high specific heat (does not easily break hydrogen bonds)
5. high latent heat
6. high heat of vaporization
7. Good solvent
hydrophilic
Organic Molecules - ANS 1. Carbohydrates
2. Nucleic Acids
3. Protein
4. Lipids
Four building blocks in catabolic reactions - ANS 1. monosaccarhides (glucose)
2. amino acids
3. fatty acids
4. nucleotides
Anabolic reaction - ANS builds larger and more complex molecules (macromolecules) from
smaller ones (require energy)
, catabolic reactions - ANS break down large chemicals and release energy
Endothermic reactions - ANS chemical reactions that absorb heat
Exothermic reactions - ANS chemical reactions that release heat
Carbohydrates - ANS Broken down to glucose to provide energy.
Glycolysis - ANS first step in releasing the energy of glucose, in which a molecule of glucose is
broken into 2 molecules of pyruvic acid
Carbohydrate Structure - ANS CH2O
Monosaccharides - ANS glucose, fructose, galactose
Disaccharides have - ANS 2 monomers of sugar
Monosaccharides have - ANS 1 carbon for 1 water molecule
Monomer - ANS a molecule that can be bonded to other identical molecules to form a polymer.
Polymer - ANS large compound formed from combinations of many monomers
Are macromolecules monomers or polymers? - ANS polymers
Lipids - ANS Energy-rich organic compounds, such as fats, oils, and waxes, that are made of
carbon, hydrogen, and oxygen.
Properties of lipids - ANS soluble in nonpolar solvents, hydrophobic, C-H bonds (hydrocarbons)
Role of lipids - ANS energy storage and structural functions
Examples of lipids - ANS fats, phospholipids, steroids,waxes
Proteins - ANS Chains of amino acids (polypeptides)
Condensation reaction - ANS loss of water when two molecule are joined
Hydrolysis reaction - ANS water is added to reactions
peptide - ANS compound of two or more amino acids
Amino acids are formed by - ANS the partial hydrolysis of protein which forms an amine bond
