The actual size of a fly's eye is 1000μm magnification=image÷ actual size (measured in mm)
image=2mm
1000μm=1mm
the picture shows the eye magnified (zoomed in) by times?
this is hard so brainliest points given

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
