An industry needs alcohol and various acid products to complete its processes. you are the industrial microbiologist and you must present an initial proposal to get the products and at the same time, save the company money. what do you suggest?
a-investigate organisms that perform butanediol fermentation.
b- build three bioreactors for three different microorganisms that perform alcoholic fermentation, homolactic fermentation and heterolactic fermentation.
c- investigate an organism that performs mixed fermentation.
d- buy the products from another industry that performs propanoic acid fermentation.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

idk and i also need to know where are those bio brainy acts lol

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!
