Biology 206 Final Exam
Regulating body temp in homeotherms(4) - Answer;--relocation
-thermogenisis
-blood flow:anatomical and functional consideration
-evaporation
Brown adipose tissue - Answer;--is one of the two fats in humans.
-activated by norepnephrine
-oxidative phosphorlation
Phagocytosis - Answer;-By the invagination of their membrane to
obtain food. Glucogen - Answer;-Released when levels are low
Insulin - Answer;-Released when levels are high
Modivates movement of material - Answer;--gravity
-hydrostatic pressure
-electrical gradients
-concentration gradients
Diffusion - Answer;-By random molecular motion, molecular
motion. Only short distances
Pump, channels, and carrier-mediated transport - Answer;-Ions/small
molecules across membrane
Osmosis - Answer;-Water movement across membranes (high to low)
Bulk flow - Answer;-Efficient, long distance, mass movement, driven
by hydrostatic pressure
Hydrostatic pressure - Answer;-Force gradients
Concentration gradients - Answer;-Entropy driven
Passive transport - Answer;-Energeticly downhill, spontaneous
process Active transport - Answer;-Energeticly uphill, requires
, -resistance of membrane
-thickness of membrane
Poiseuille's Equation - Answer;-Measures the volume flow rate
-cross sectional area of a pipe
-pressure gradient
-viscosity
What would increase the flow? - Answer;--increase radius
-lower viscosity
-increase pressure gradient
What do plants require water for? - Answer;--support
-chemical reactions
-temperature control
-transport of solutes
How is the atmosphere lossed to the environment? - Answer;-Via the
evaporation in the leaves via the stomata
Stomata exchanges what? - Answer;-Gases
-CO2 and O2
-N2, ethylene
-H2O vapor
Phloem transports? - Answer;-sugar, hormones, and amino acids
Apoplast - Answer;-Is the "fast lane." The cell wall continuum of a
plant`
Symplast - Answer;-Is the "slow lane." Uses the interconnected
protoplasts via their plasmodesmata
Casparian Strips - Answer;-acts as a seal that prevents water and
ions moving through the opposite space
What is the casparian strip made out of? - Answer;-it is impregnated
with the wax-like, hydrophobic substance, suberin
How does the water move into the xylem - Answer;-moves via
osmosis What does the apoplastic pathway have to do at the
