What is Life?
Who is Karl Popper? What was his theory?
Philosopher of science
Falsification - validity is dependent on whether the theory is proven wrong
What is more electronegative iron or oxygen? What type of bond do they form?
Oxygen is more electron negative (electronegativity increases to the right)
They form an ionic bond (metal to no metal = transfer ions)
What are the 4 most abundant elements in the body? How many valence electrons do each have?
H = 1, O = 6, N = 5, C = 4
What is the chemical composition of a protein?
Amino, side chain, carboxy group
What is an example of a utilitarian ethical system? Give a scenario
An organ donor organ going to a person in need
Utilitarian - does the act result in an outcome positive for all people
What is the difference between cohesion and adhesion? Where do we see this?
Cohesion is the act where water molecules stick to each other
Adhesion is the act where water molecules are attached to other molecules/objects
In trees!!
Functional groups contribute to molecular structure and function. Give me examples of 2 functional groups that can be attached to carbons.
Hydroxyl (alcohol)
Carbonyl (c double bond o)
Carboxyl (COOH)
Amino (NH2)
Sulfhydryl (SH)
Phosphate (OPO3)
Methyl (CH3)
Carbohydrates can be _______ meaning one or _______ meaning many connected by ______ bonds.
Monosaccharides, Polysaccharides, glycosidic bonds
What is the system scientists use to categorize and study animals?
Taxonomy
Which shows more acid, base, and equilibrium? (will draw)
A = Equilibrium, B = basic, C = acidic
What functional groups are seen here? Will draw on board
Amino and hydroxyl
What is the process that builds up monomers to polymers? What breaks polymers apart?
Dehydration
Hydrolysis
What is the difference between inductive and deductive reasoning?
Inductive = reasoning from observation - forms theory
Deductive = reasoning from tested information - test theory
Water molecules are unique in that they can form _____ bonds with each other because the electrical charge distribution is not even: The oxygen atom is ____ charged and the hydrogen atom is _____ charged
Hydrogen, negatively, positively
What are the 3 types of isomers? Draw examples
structural, enantiomers, cis-trans
Lipids are made of __________ chains. These chains are nonpolar and _______.
hydrocarbon , hydrophobic
Dr.Marshall drank a culture of H. pylori to study ulcers more. How would ethics Pragmatism see his act?
Not ethical - there could have been a better use of the resources
Pragmatism - what is the best way to use resources
What is the difference between nonpolar and polar covalent bonding? What is an example of both?
Nonpolar = equal sharing (H - H)
Polar = non-equal sharing (Cl - H)
What feature does silicon share with carbon?
Four electrons in their valence shell
What type of macromolecules do DNA and RNA have in them? And what is that macromolecule made of?
Nucleic acid: Phosphate group, sugar, nitrogenous base
