PLEASE HELP ME NOW Deshawn is conducting an experiment about fermentation. He prepares six bottles. The table shows what he puts in each bottle.

bottle 1: 1 cup cold water, 1 packet yeast

bottle 2: 1 cup cold water. 1 packet yeast 2 tablespoons sugar

bottle 3: 1 cup lukewarm water, 1 packet yeast

bottle 4: 1 cup lukewarm water, 1 packet yeast 2 tablespoons sugar

bottle 5: 1 cup hot water, 1 packet yeast

bottle 6: 1 cup hot water, 1 packet yeast 2 tablespoons sugar

He swirls the bottles until the yeast dissolves and puts a balloon over the neck of each bottle. In 20 minutes,
he will check and see what has happened.

what question is being asked through this scientific investigation?

Amount of liquid measured in l or lm

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
