Rank the types of molecules from 1-4, 1 being passes through the cell membrane with the most ease and 4 being possess with most difficulty.

Small, polar/hydrophilic molecules (Ex. H20)

Charged lons (Ex. K+)

Small, non polar hydrophobic molecules (Ex. 02)

Large, polar/hydrophilic molecules (Ex.
C6H1206)

biology is the study of life. it is the study of living organism.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

: -)

i'll try what topic lol
