The process carried out by yeast that causes bread to rise is cellular respiration
yeast mitosis
alcoholic
fermentation
lactic acid
fermentation

the answer is a) cell division.

hope this !

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
