Answer:

Lactose present, glucose absent.

Explanation:

Lac operon may be defined as a cluster of genes that regulate the metabolism of lactose in bacteria. The bacteria always prefer glucose if both glucose and lactose is present in the medium.

The conditions that causes the maximal expression of lactose is the presence of lactose and absence of glucose. This is due to the action of catabolite activator protein and cyclicAMP.

Thus, the correct answer is option (1).

Answer:

Explanation:

1. The processes of diffusion in diagram A and B is that one side of the membrane is hypertonic. The other side is hypotonic. Based on this, Diagram A shows that the one space has no solute particles causing the particles to move against gradiation. The movement is shown in Diagram B. This process is used to equalize the solute particles in the solution.

2. In the diagram C, we can see that enough particals have moved over to the other side, or against the concentration gradient. The solution is now isotonic or equilibrium.
