EXAM QUESTIONS WITH CORRECT
ANSWERS
Prokaryotic |Cells |- |CORRECT |ANSWER✔✔-- |cells |that |lack |a |nucleus
- |approx |10x |as |many |prok |then |euk |cells
- |make |up |2-3% |or |body |mass |
- |most |are |harmless |
(harmful |cells |are |contained |and |managed |by |immune |system |to |keep |them |under |control)
- |provide |essential |functions |throughout |the |physiological |systems |
EG: |bacterial |cells
Eukaryotic |Cells |- |CORRECT |ANSWER✔✔-- |cells |have |a |nucleus |containing |most |of |the |genetic |
material |
- |each |cell |contains |the |same |genetic |heritage |as |the |original |fertilized |cell, |but |they |differ |in |
function |(muscle, |kidney, |skin, |neuron)
EG: |plant |cells, |animal |cells, |fungi
Estimated |number |of |cells |in |the |human |body |- |CORRECT |ANSWER✔✔-10 |trillion
Microbiome |- |CORRECT |ANSWER✔✔--a |populaiton |of |microorganisms |or |microbes
, - |approx |10 |000 |distinct |species |of |microbes |on |and |in |a |healthy |human |body |(found |
everywhere)
(includes |prok |bacteria |and |small |euk |organisms)
Microorganisms |- |CORRECT |ANSWER✔✔-organisms |that |re |only |visible |under |a |microscope
Examples |of |Human |Microbes |- |CORRECT |ANSWER✔✔-1. |Streptococcus |Salivarius
2. |Staphylococcus |Haemolyticus
3. |Bacteroides |Thetaiotaomicron
Streptococcus |Salivarius |- |CORRECT |ANSWER✔✔-- |normal |inhabitant |of |the |upper |respiratory |
tract |and |oral |cavity
- |collection |of |bacteria |that |contribute |to |formation |of |dental |plaque
Staphylococcus |Haemolyticus |- |CORRECT |ANSWER✔✔-- |resides |on |our |skin
(harmless, |unless |it |enters |the |body)
Bacteroides |Thetaiotaomicron |- |CORRECT |ANSWER✔✔-- |predominant |intestinal |bacteria
- |makes |enzymes |useful |in |the |breakdown |of |plant |materials |that |we |ingest |(ie. |oat |fibre)
A |Cell |- |CORRECT |ANSWER✔✔-membrane |bound |structure |containing |macromolecules
Four |Classes |of |Macromolecules |- |CORRECT |ANSWER✔✔-1) |Nucleic |Acids |(DNA |& |RNA)
-make |up |hereditary |material |of |cell
