C. Theres decreased Biodiversity Most likely because of natural or human causes (deforistation)
The separation of molecules. I wouldn't put that if i were you.
Because proteins are basically building blocks which mean that they only fit to specific pieces.
Of course, at STP, dioxygen is a gas, but 10.0 g is still 10.0 g. We could calculate its volume at STP, which is 22.4 L × its molar quantity, approx. 8⋅L . There are 1.51×1023molecules O2 in 10.0 g O2 .
we have
work done (W)= force(F) × displacemen(s)
or, 80= F× 8
or, F= 10 N
therefore, 10 N force is required to lift the rock.
