I'm not regular math, i'm cool math (statistics). But also experiments.
Sets a baseline in an experiment, and used to ensure no confounding variable has affected the results.
What is negative control?
A substance that cannot be broken down into other substances by chemical reactions.
What is an element?
Unequal sharing of the electrons make water a polar molecule.
What is polarity?
Molecule with amino and carboxyl group.
Carbon can use its valence electrons to form covalent bonds to other carbons and this links carbons into a chain.
What are carbon chains?
The group exposed to the independent variable
What is independent variable?
Simplified Bohr models. Doesn't show energy levels, only electrons in the valence shell. Electrons placed around the element symbol.
What is Lewis Dot Model?
The upward movement of water due to the forces of cohesion, adhesion, and surface tension.
What is capillary action?
many sugars joined through dehydration reactions. Storage: plants store starch, allows plants to store excess glucose. Structural: animal store glycogen, stored in liver and muscle cells.
What are polysaccharides?
Chemical groups attached to the carbon skeleton that participate in chemical reactions.
What are functional groups?
A type of logic in which specific results are predicted from a general premise.
What is deductive reasoning?
Metal transfers electrons to nonmetals; attraction between oppositely charged atoms/ions.
What are ionic bonds?
As water solidifies it expands and becomes less dense.
What is density?
Break the bonds in a polymer by adding H2O. H- of H2O bonds to one monomer and the remaining OH- of the H2O attaches to the other monomer
What is hydrolysis reaction?
A substance that increases the hydrogen ion concentration of a solution
The hypothesis that there is no difference between specified populations.
What is null hypothesis?
The measure of an atom's ability to attract electrons
What is electronegativity?
Water has a high heat of vaporization, the molecules with the highest kinetic energy leave as gas. This property moderates Earth's climate, stabilizes temperature in lakes and ponds, prevents terrestrial organisms from overheating, prevents leaves from becoming too warm in the Sun.
What is evaporative cooling?
Antibody, enzyme, messenger, structural, transport/storage.
What are functions of proteins?
A lipid made up of glycerol joined to 2 fatty acids and a phosphate group. The hydrocarbon chains of the fatty acids act as nonpolar, hydrophobic tails, while the rest of the molecule acts as a polar, hydrophilic head. These form bilayers that function as biological membranes
What is phopholipid?
s/sqrt(n). used to determine the precision of and confidence in the mean value
What is standard error of the mean?
The partially positive hydrogen atom in one polar covalent molecule will be attracted to an electronegative atom in another polar covalent molecule.
What is hydrogen bonding?
H2O resists changes in temperature because he must be absorbed to break hydrogen bonds but heat is released when hydrogen bonds form. This property moderates air temperature, stabilizes ocean temperature, and organisms can resist changes in their own internal temperature.
What is high specific heat applied to H2O?
Phosphate groups link adjacent nucleotides, phosphodiester linkage 5' to 3' directionality.
Lipids that have 4 fused rings. Unique groups attached to the ring determine type. Ex. tesotosterone.
What is steroid?
