PSU BIO 110 Exam 1 Questions With Complete Solutions
1st living organisms appeared Correct Answers 4-3.5bya
3 domain classification Correct Answers Bacteria, Archae,
Eukarya
Achaea Correct Answers -cell walls have peptidoglycen, unique
cell membrane lipids, some genes have nitrons, mostly anerobic,
previously known as extremophiles
All life made out of Correct Answers water, carbs, proteins,
lipids,sugars,nucleic acids
Archae and Eukarya Correct Answers are more closely related
than bacteria and archae
Bacteria Correct Answers -no peptidoglycen, no nitrons or junk
DNA, some are photosynthetic
capillary action Correct Answers The combination of adhesion
and cohesion that allows water to travel up small spaces- plants
need it
carbohydrate (sugars) Correct Answers -made of
carbon,hydrogen,and oxygen
-energy, structural support, and cell recognition
-monomers are monosaccarides
-startch for plant energy storage, chitin and cellulose for
structural support , glycogen for energy storage in animals
, commensalism Correct Answers neither benefit nor harm
conjugation Correct Answers requires a partner, sex without
reproduction, F is fertile cell, copies f plasmid
Dechronology good for Correct Answers <9000 , accurate to
the season. most accurate. good for climate
dietary lipids Correct Answers -main component is fatty acid
-saturated fat- max number of double bonds, folds in nicely so
solid
-unsaturated fat- not full of double bonds, doesnt fold nicely so
liquid
dissacarides Correct Answers dehydration synthesis reaction
between two monosaccarides
DNA Correct Answers DEOXYRIBOSE, double stranded,
ATGC, instructions for making proteins , bases ATGC
DNA polarity Correct Answers two strands run upside down
Domain system Correct Answers Bacteria, Archae, Eukarya,
Earth is how old? Correct Answers 4.5b
Eukaryotes Correct Answers membrane bound organelles,
bigger, linear chromosones,divide by mitosis or
meiosis,multicellular,flagella made of tubulin,metabolically
more diverse
