Experimental Design and Statistics
The value that appears most often in a data set
What is mode?
The five essential elements for life (Need all 5 to get the points)
What is CHONP?
Carbon, Hydrogen, Oxygen, Nitrogen and Phosphorous
The type of reaction seen in all 4 macromolecules in order to link monomers together and form polymers.
What is a dehydration reaction?
A difference between DNA and RNA. (Be specific)
What is double vs single stranded?
What is thymine vs uracil?
What is deoxyribose vs ribose?
A positively charged ion.
What is a cation?
A hypothesis that states that there is no difference between two groups of data, and the experimental observations are due to chance
What is a null hypothesis?
The attraction of molecules for other molecules of the same kind
What is cohesion?
Element ratio in carbohydrates
What is 1:2:1?
The directionality of polynucleotides.
What is 5' to 3'?
The # of electrons that most elements want in their valence shell.
What is 8?
A group not exposed to the independent variable but is exposed to a treatment known to have an expected effect.
What is a positive control?
Electrons are shared equally between two atoms. (Full name to get the points)
What is a nonpolar covalent bond?
A lipid that is both hydrophobic and hydrophilic.
What are phospholipids?
Three structural components that all amino acids have in common. (Not the elements and you need all three to get the points)
What are an amino group, a carboxyl group, an R group (variable side chain), and an alpha carbon?
The type of reaction seen in all 4 macromolecules that breaks down polymers into monomers.
The one factor that is changed between groups in an experiment.
What is the independent variable?
The dissolving agent in a solution
What is a solvent?
The monomer of carbohydrates
What are monosaccharides?
The side chain contained by hydrophobic amino acids.
What is nonpolar side chain?
The general structure of amino acids. (Draw it)
What is (insert image here)?
An alpha carbon connected to an amino group, a carboxyl group, an R group and a hydrogen?
The difference between the means is not statistically significant; any observed difference is likely due to chance
What are overlapping error bars?
A benefit to living organisms due to waters high specific heat.
What is resisting changes in internal temperatures?
What is stabilized ocean temperatures for marine life?
The two "monomers" of lipids. (Need both to get the points)
What are fatty acids and glycerol?
What are cytosine, thymine and uracil?
The name of the covalent bond that links nucleotides together in a polynucleotide.
What is phosphodiester linkage?
