The cook should compare 3 and 4.

Yeast is an unicellular fungi whose scientific name is Saccharomyces cerevisiae. This organism is an anaerobic fungi which performs alcoholic fermentation. The alcoholic fermentation is done by the enzyme zymase which is a mixture of different enzymes. This enzymes acts on glucose to form the ethyl alcohol and carbon dioxide from glucose.

Glucose - > 2 Ethanol + 2CO2.

In an open system, the carbon dioxide will evolve as gas and leave the system. So in the container with yeast, the container will loose weight but the other one won't loose any weight.

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.

i dont know it at allnow im just getting points at this pint
