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

Athelose and glucose.

Explanation:

The ath operon most likely controlled due to the presence of athelose in small amount because ath operon are expressed only when the concentration of athelose in the bacterium is high. The smaller amount of athelose can be gained if glucose is present to the bacterium in sufficient amount or quantity so we can say that glucose quantity control the amount of athelose and it will control the ath operon.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
