Ch.1
Define a Hypothesis
An if then statement predicting the outcome of an experiment.
I- Ions are attracted
C- Atoms share electrons
What defines if a compound is organic or inorganic?
Carbon-Hydrogen Bonds
What are mitochondria?
Powerhouse of the Cell
Define Diffusion.
Particles move from a high to low concentration naturally.
Define Independent and Dependent Variables
I- Not dependent on experiment.
D- Dependent on experiment.
Name the 4 main biomolecules.
Carbohydrates, Lipids, Protein, Nucleic Acid
Contrast the two types of cells, Pro and Eukarotic.
P- Nucleoid, Cytosol, Chromosomes, Ribosomes.
E- Nucleus, Membrane-bound Organelles, Plasma Membrane.
Define Hypo, Iso, and Hypertonic states.
Cells that are gaining, at equilibrium, or losing water due to concentration of solutes in solution.
What is the core theme of biology.
Unity and Diversity.
Define Hydrogen Bonds
Polar Molecules attracted to each other, eg. water.
Carbohydrates are primarily formed by these sugar units.
Mono,dia,poly-saccharides.
Explain optimal cell SA:V.
High SA:V are more efficient in taking in materials and removing waste.
Plasma Membrane Model, Explain.
Fluid Mosaic Model, lipid bi-layer with associated carbohydrates and proteins used for transport and metabolism.
5 Common Themes of Biology
Organization, Information, Energy & Matter, Interactions, Evolution
Contrast Solutions and Mixtures
M- Physical Combination
S- Homogenous Mixtures
Define the difference between unsaturated and saturated lipid structure.
Define the purpose of chloroplasts.
Photosynthesis and green.
Give an example of cell signaling.
Contrast inductive and deductive reasoning.
I- Specifics to Generalities
D- Generalities to Specifics
Ionic compounds do what in water?
What is dissociate.
Name and explain all the levels of protein structure.
Primary, Secondary, Tertiary, Quaternary. Chain, Helix or Pleat, 3D, combined 3D.
Name the three cellular junctions.
Tight, Gap, Desmosomes.
Endocytosis- Taking in groups of particles that cannot fit through the membrane via. a visticle.
Exocytosis- Same but removing particles.
