In this experiment of Monod's the b-galactosidase enzyme appeared almost immediately when lactose was added to growing culture in the presence of lactose activates a pre-existing , but inactive , b-galactosidase.

Monod's experiment with the E.coli to see if when exposed to sugars, those cells always produced new enzymes or if instead they had enzymes that rearranged themselves. According to  this - the set of genes that are transcribed in the prokaryotes are under the control of operons.

An enzymes b- gaalactosidase cleaves the disaccharide lactose by which it produce the galactose and glucose which then ultimately enter in process of glycolysis. Also causes transgalactosylation reaction of lactose to allolactose.

RUDIKE [14]

Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.

Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.

This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

This compressed, slender body shape is beneficial because it allows the fish to easily fit into vertical crevices. This is probably why the fish live on coral reefs and in rocky areas, because there are enough crevices for these fish to fit into.
