17. the eyepiece of a compound light
microscope has a magnification of 10x and the low-power objective and high-power objective lenses have magnifications of 10x and 30%, respectively. if the diameter of the
low-power field measures 1500 micrometers, the diameter of the high-power field will
measure either 4500 micrometers or 500 micrometers.
select the correct diameter. support your
answer.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

the answer is c. it will give up it's valence electron to the other atom.
