SEP Design Your Solution Biosphere 2 was an attempt to have humans live within a perfectly closed system, as a model for living on other planets. The first attempt
failed because the system began losing CO2, which was chemically reacting with
the exposed concrete walls. How would you go about designing a habitat that is a
closed system? Explain how matter and energy would flow within the system.

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

"electrical energy" transforms to "thermal energy".hope my answer has you : )
