2.
Molecules in water or in the air will always 'spread out' - like when you drop color in water, or release perfume from a bottle. Which of the statements about this process is FALSE? THERE IS ONLY ONE CORRECT ANSWER!
a)
this process is called diffusion
b)
this happens because molecules are always moving
c)
the molecules will eventually reach equilibrium, where they are equally spread though the container.
d)
when this happens, molecules are moving with the concentration gradient (from high concentration to low concentration)
e)
this process requires ATP energy to make happen
3.
Which is the TRUE statement?
a)
Molecules in A and B are both going with the concentration gradient (from high to low)
b)
Molecules in A and B are both going against the concentration gradient (from low to high)
c)
Molecules in A are going with the gradient, while molecules in B are going against
d)
Molecules in B are going with the gradient, while molecules in A are going against
