You are studying a bacterium that utilizes a sugar called athelose. this sugar can be used as an energy source when necessary. metabolism of athelose is controlled by the ath operon. the genes of the ath operon code for the enzymes necessary to use athelose as an energy source. you have found the following: the genes of the ath operon are expressed only when the concentration of athelose in the bacterium is high. when glucose is absent, the bacterium needs to metabolize athelose as an energy source as much as possible. the same catabolite activator protein (cap) involved with the lac operon interacts with the ath operon. based on this information, how is the ath operon most likely controlled?

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
