POB Shadwick UARK Exam 1 Questions and Answers
Emergent Property - -a property that a complex system has but the individual members of
the system do not (ex:NaCl, not salty individually, only together)
-Qualities of Life - -- Are organized
- Acquire materials and energy
- Reproduce
- Respond to stimuli
- Homeostatic
-Grow and develop
- Have the capacity to adapt
-Law - -describes a pattern in nature; the what (ex: Law of Evolution)
-Theory - -explanation to why a pattern exists; the why (The theory of evolution by
natural selection)
-Null Hypothesis - -NO difference between control and experimental, experimental will
have no effect
-Alternative Hypothesis - -expect a difference between groups
-Inductive Reasoning - -makes generalization based on collecting and analyzing a large
number of specific observations. (This dog has 4 legs so all dogs must have 4 legs. )
-Deductive reasoning - -flows from general premises to predicted and specific results (All
dogs have 4 legs, since this is a dog, it should have 4 legs)
-Independent variable - -variable that is manipulated
-Dependent variable - -changes in response to the independent variable
-confounding variable - -extra variables that interfere
-blind study - -When the participant and/or researcher does not know which conditions
they are in/analyzing. This can reduce experimenter biases
-double blind study - -when both groups in a study (control group and experimental
group) don't know if they are getting the drug (treatment) or a placebo
-lactose - -a sugar in milk
--ose - -sugar
, -lactase - -an enzyme that breaks down lactose
--ase - -enzyme
-lactose intolerant people do not produce enough _____ to break down sugar - -lactase
-Protons are ______ charged - -positively
-how do you find the number of protons? - -atomic number
-electrons are ___ charged - -negatively
-neutrons are ____ - -neutral
-Isotopes - -atoms of the same element with different number of neutrons
-Isomers - -same number of atoms in each element but have different arrangements of
their atoms (lewis structure)
-Ionic bonding - -transfers electrons
-covalent bonding - -sharing electrons
-nonpolar - -equal sharing of electrons
-polar - -unequal sharing of electrons
-hydrogen bonding - -slightly negative oxygen attracts to slightly positive hydrogen, weak
individually but strong together
-properties of water - -high heat capacity, high heat of vaporization, can dissolve many
molecules, high surface tension, cohesion, adhesion
-cohesion - -cling to other water molecules
-adhesion - -cling to other polar surfaces
-Water has a __________ surface tension - -high
-acids - -high H+ concentration
pH 1-7
-bases - -low H+ concentration
pH 7-14
