Biology 1110 exam 1 study guide with correct
answers
Biology |- |✔✔the |scientific |study |of |life
life |- |✔✔defined |by |its |basic |componets
Characteristics |of |life |- |✔✔organization, |use |energy, |able |to |maintain |internal |constancy,
|Reproduce/grow/develop, |Evolve
Organization |- |✔✔composed |of |an |atom, |molecule, |organelle, |cell, |tissue, |organ, |organ |system, |
organism, |population, |community, |Ecosystem, |Biosphere. |It |also |has |to |do |with |the |hierarchy |of |life. |
Ex. |Atoms |make |up |molecules, |which |make |up |cells, |which |make |up |tissues, |and |so |on.
use |energy |- |✔✔used |to |maintain |metabolism, |and |is |composed |of |consumers-what |we |are, |
producers-organisms |that |make |their |own |food, |and |decomposers-consume |waste |or |dead |organisms.
|also |consist |of |fungi. |Ex. |A |kitten |uses |the |energy |from |its |mothers |milk |to |fuel |its |own |growth
maintains |an |internal |constancy |- |✔✔has |to |do |with |Homeostasis-maintenance |of |a |internal |
constancy. |regulated |though |neg |and |pos |feedback. |Ex. |Your |kidneys |regulate |your |body's |water |
balance |by |adjusting |the |concentration |of |your |urine.
Reproduce, |grow, |and |develop |- |✔✔consists |of |sexual |and |asexual |types |of |reproduction. |Ex. |An |
acorn |germinates, |develops |into |an |oak |seeding |, |and, |at |maturity, |reproduces |sexually |to |produce |its
|own |acorns
Evolve |- |✔✔has |to |do |with |adaptations, |Natural |selection, |which |leads |to |Evolution |all |composed |by |
Charles |Darwin. |Ex. |Increasing |numbers |of |bacteria |survive |treatment |with |antibiotic |drugs.
What |is |an |emergent |property? |- |✔✔quality |that |results |from |interactions |of |a |system's |components
How |does |an |emergent |property |relate |to |the |function |of |something? |- |✔✔by |knowing |that |the |
whole |is |greater |than |individual |parts.
What |is |Natural |selection? |- |✔✔the |fact |that |some |organisms |are |better |suited |than |others |which |is |
more |organisms |than |resources |can |support; |but |they |also |have |to |reproduce.
Who |came |up |with |Natural |selection? |- |✔✔Charles |Darwin
What |role |has |evolution |played |in |the |study |of |biology? |- |✔✔evolution |has |to |do |with |the |genetic |
change |in |a |population |over |time.
Who |came |up |with |the |overall |classification |scheme? |- |✔✔Melvil |Dewey
Who |came |up |with |the |domains? |- |✔✔Carl |Woese
, what |is |the |hierarchical |classification |of |life? |- |✔✔Along |with |taxonomy, |it |is |composed |of |Domain, |
Kingdom, |Phylum, |Class, |Order, |Family, |Genus, |Species
What |is |science? |- |✔✔the |intellectual |and |practical |activity |encompassing |the |systematic |study |of |the
|structure |and |behavior |of |the |physical |and |natural |world |through |observation |and |experiment.
What |are |the |different |types |of |variables? |- |✔✔independent, |dependent, |controlled
What |are |the |different |types |of |controls? |- |✔✔feed |forward, |concurrent |control, |Feedback |control
Theory |- |✔✔An |evidence |based |explanation |for |a |natural |phenomenon
Scientific |Theory |- |✔✔Widely |accepted, |used |to |predict, |encompasses |multiple |hypotheses, |is |
testable
What |are |the |basis |parts |of |an |experimental |design? |- |✔✔observations/questions,
|Hypothesis/prediction, |data |collection, |analysis |data/conclusion, |peer |review/sharing |data
What |is |chemistry |and |what |does |it |study? |- |✔✔Chemistry |is |the |study |of |matter
Why |do |we |care |about |chemistry |even |though |this |is |a |biology |class? |- |✔✔
matter |- |✔✔Anything |that |has |a |mass |and |takes |up |space
elements |- |✔✔pure |chemical |substance
atom |- |✔✔a |particle |of |matter |which |is |composed |of |protons, |neutrons, |and |electrons
subatomic |particles |- |✔✔particles |much |smaller |than |atoms.
How |are |the |properties |of |elements |determined? |- |✔✔
bulk |elements |- |✔✔an |element |that |an |organism |requires |in |large |amounts
trace |elements |- |✔✔an |element |that |an |organism |requires |in |small |amounts
What |are |the |3 |subatomic |particles |and |their |charges? |- |✔✔protons=pos
neutrons=uncharged
electrons=neg
atomic |number |- |✔✔the |number |of |protons |in |an |atoms |nucleus
atomic |mass |- |✔✔the |average |mass |of |all |isotopes |of |an |element.
What |is |an |ion |and |how |is |it |formed? |- |✔✔an |atom |or |group |of |atoms |that |has |lost |or |gained |
electrons.
What |is |an |isotope, |what |do |we |use |them |for? |- |✔✔atoms |with |the |same |atomic |# |but |different |
atomic |weights. |We |use |isotopes |for |medical |research, |data |collecting, |etc.
molecule |- |✔✔2 |or |more |atoms |combined
compound |- |✔✔combining |of |different |elements
