BIOL 1P92 Final Exam Review Questions With
Correct Answers
Which |tissues |contract? |- |CORRECT |ANSWER✔✔-Muscle |tissue |contracts:
- |skeletal
- |smooth
- |cardiac
Out-pouching |of |esophagus |in |birds |- |CORRECT |ANSWER✔✔-The |lower |esophageal |of |birds |is |
called |the |crop |and |it |is |an |area |where |birds |can |store |things
What |is |Darwinian |fitness? |- |CORRECT |ANSWER✔✔-It |is |the |relative |likelihood |that |a |
genotype |will |contribute |to |the |gene |pool |of |the |next |generation |as |compared |with |other |
generations |
It |is |a |measure |of |reproductive |success(not |physical)
Uses |the |letter |W |to |measure |and |they |all |have |to |add |to |1.0
The |one |that |produces |the |most |offspring |become |the |denominator
In |mammals |what's |the |primary |site |of |nutrient |absorption? |- |CORRECT |ANSWER✔✔-90% |of |
digestion |occurs |in |the |small |intestine |
the |rest |occurs |in |the |mouth |and |large |intestine
,What |is |Emulsification? |- |CORRECT |ANSWER✔✔-It |is |a |process |during |digestion |that |disrupts |
large |lipid |droplets |into |many |tiny |droplets, |thereby |increasing |their |total |surface |area |and |
exposure |to |lipase |
It |is |a |way |to |properly |digest |fat |by |breaking |lumps |of |lipids |into |smaller |globules
Why |is |it |more |difficult |for |smaller |birds |to |maintain |their |body |temps |than |larger |birds? |- |
CORRECT |ANSWER✔✔-Larger |animals |have |a |smaller |ratio |of |surface |area |to |volume |and |it |
makes |them |better |at |conserving |heat |
Smaller |snails |are |more |efficient |at |diffusion |because |their |surface |area |to |volume |ratio |is |
much |bigger
Mammals |and |insects |and |what |is |similar |in |their |respiratory |systems |- |CORRECT |ANSWER✔✔-
In |both |respiratory |systems, |tubes |are |used |to |convey |air |throughout |the |system |
There |are |thing |cells |at |the |junction |between |the |air |and |the |cell |
Both |have |very |similar |structure |of |getting |air |into |the |body |and |to |the |cells |that |need |oxygen
Fats |vs. |Carbohydrates |(in |terms |of |digestion |and |absorption) |- |CORRECT |ANSWER✔✔-
CARBOHYDRATES
*some |polysaccharide |digestion |occurs |in |the |mouth, |but |most |takes |place |in |the |small |
intestine |by |pancreatic |amylase, |producing |maltose
*maltose |and |other |disaccharides |broken |down |by |enzymes |on |brush |border |of |small |intestine
*monosaccharides |transported |across |intestinal |epithelium |into |the |blood |
FATS
*ingested |as |triglycerides |
, *digestion |occurs |almost |entirely |in |small |intestine |
*emulsification
~increases |the |S.A, |providing |greater |exposure |to |lipase |
~muscular |contractions |break |up |large |droplets
Vertebrates |and |sea |squirts |(chordates) |(what |they |share, |characteristics) |- |CORRECT |
ANSWER✔✔-Suspension |feeding |
*filter |organic |matter |out |of |water
Supergroup |amebozoa |(the |way |that |they |move) |- |CORRECT |ANSWER✔✔-They |move |by |
pseudopodia, |which |involves |extending |cytoplasm |into |filaments |or |lobes
Difference |between |in |zygotic |and |sporic |life |cycles |- |CORRECT |ANSWER✔✔-ZYGOTIC |
*simpler |
*spends |more |time |in |mitosis |and |fertilization |
*haploid |gametophyte |tissue |makes |gametes |by |mitosis |
*only |a |few |haploid |spores |produced |per |zygote |
SPORIC |
*four |steps |to |it |
*goes |through |mitosis |twice |
*after |the |first |mitosis |step, |a |new |multicellular |diploid |sporophyte |forms
Traits |that |are |shared |between |plants |and |streptophyte |algae |(what |they |don't |share) |- |
CORRECT |ANSWER✔✔-They |share:
*photosynthetic |features |
*reproductive |features |
