N |- |itrogen
P |- |hosphate
S |- |ulphur
What |are |four |terms |that |describe |an |organisms |source |of |Carbon |and |Energy? |- |CORRECT |
ANSWER✔✔-Photoautotrophos, |chemoautotrophs, |chemoheterotrophs, |lithoautotrophs
Define |Saprobe: |- |CORRECT |ANSWER✔✔-A |microbe |that |decomposes |organic |remains |from |
dead |organisms
Define |Parasite |- |CORRECT |ANSWER✔✔-An |organism |that |lives |in |or |within |a |host |from |which |
it |obtains |nutrients |and |enjoys |protection. |Produces |some |degree |of |harm |to |host
Define |Diffusion: |- |CORRECT |ANSWER✔✔-movement |from |high |to |low
Define |Osmosis: |- |CORRECT |ANSWER✔✔-Diffusion |of |water |through |a |selectively |permeable |
membrane
hypotonic |cell: |- |CORRECT |ANSWER✔✔-cells |that |are |less |concentrated |than |their |
environment; |water |rushes |in, |may |burst |cell
hypertonic |cell: |- |CORRECT |ANSWER✔✔-cells |that |are |more |concentrated |than |their |
environment; |water |rushes |out |of |the |cell |causing |it |to |shrivel
isotonic |cell: |- |CORRECT |ANSWER✔✔-extracellular |environment |has |the |same |concentration |
of |solutes |as |the |cell |cytoplasm
, types |of |passive |transport |- |CORRECT |ANSWER✔✔-Facilitated |diffusion, |molecule-specific, |
simple |diffusion
facilitated |diffusion |- |CORRECT |ANSWER✔✔-passive |transport: |Movement |of |specific |
molecules |across |cell |membranes |through |protein |channels |by |binding |to |receptors
molecule |specific
transport |- |CORRECT |ANSWER✔✔-Passive |transport |goes |both |directions. |Rate |is |limited |by |
number |of |binding |sites |on |transport |proteins
simple |diffusion |- |CORRECT |ANSWER✔✔-Fundamental |property |of |atoms |and |molecults |that |
exist |in |a |state |of |random |motion
Name |three |types |of |active |transport: |- |CORRECT |ANSWER✔✔-Carrier |mediated, |group |
translocation, |bulk |transport
Carrier-mediated |Transport |is... |- |CORRECT |ANSWER✔✔-Active |transport |where |atoms |or |
molecules |are |pumped |into |or |out |of |the |cell |by |specialized |receptors
Group |translocation |transport |is.... |- |CORRECT |ANSWER✔✔-Active |transport |where |molecule |
is |moved |across |membrane |and |converted |to |a |metabolically |useful |substance
Bulk |transport |is.... |- |CORRECT |ANSWER✔✔-active |transport |of |large |particles/cells/liquids |by |
enfulcing |in |a |vesicle |(e.g. |endocytosis, |phagocytosis, |etc.)
Ways |in |which |different |organisms |dead |with |oxygen... |- |CORRECT |ANSWER✔✔-Can |use |
oxygen |and |detoxify |is, |can |neither |use |nor |detoxify |is, |cannot |use |but |can |detoxify |it.
