I’m not 100% positive but quartz would make sense
1)a) 2.4/4=0.6
b)250x10^(-3)/12=1/48g
c)15/58.5=10/39
d)40/256.8=50/321g
a)1.2x39.1=46.92g
b)75x2=150g
c)0.25x18=4.5
d)0.15x159.6=23.94g
Climate change is consuming because there is lots of clear cutting and co2 that creates gases that are trapped into the atmosphere and there are lots of green house gases which produce more heat than the earth's atmosphere can take
In cellular biology, active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses ATP, and secondary active transport that uses an electrochemical gradient. An example of active transport in human physiology is the uptake of glucose in the intestines.
Answer:
591.25ml
