Answer:
1000 µL; 10 µL
Explanation:
A p1000 micropipet is set to dispense 1000 µL.
A p10 micropipet set to dispense 10 µL.
If there is more soil, there would be more plants, and thus, more organisms, depending on if the soil has enough nutrients to support an ecosystem. The way that this would affect the climate is that it would transpire moisture into the atmosphere, and also generate fresher air through photosynthesis.
I would say that the organism that is responsible for clean up in this ecosystem are decomposers. They <span>are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition. Hope this answers the question.</span>
Answer:
Explanation:
half life = 1600 years .
m = M x 
m is mass of the radioactive object after n half lives , M is original mass.
n = 4800 / 1600
= 4
Putting the valus of n and M we have
m = .25 x 
= .03125 g .
