The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent.
<h3>How is the lac operon triggered by E. coli?</h3>
The lac operon of E. coli contains genes related to lactose metabolism. Only when lactose and glucose levels are low does it manifest symptoms. Two regulators that control the operon's "on" and "off" states in response to lactose and glucose concentrations are lac repressor and catabolite activator protein (CAP).
<h3>Why does E. coli prefer glucose to lactose?</h3>
Because it promotes quicker development than other sugars and is the first sugar to be consumed in sugar combinations, glucose is frequently the best carbon source for E. coli.

I think it is c but I’m not 100% sure so wait for someone else to answer too maybe ?
The correct answer is D, white blood cells.
We know that red blood cells deliver nutrients and are not apart of the immune system; platelets are responsible for coagulation, which has nothing to do with the immune system, and plasma is a substance that, again, has nothing to do with immunity. White blood cells are the only things that fight disease (antibodies are white blood cells)!
I hope I helped!

GM foods should be labeled in food stores. If, for example, someone wanted to buy a GM Apple, which could be enriched in chemicals, that should be labeled different than a regular apple. What if someone was allergic to some of the modifications in that apple. If there was a label on that apple, that person would not get a allergic reaction. That is why GM products should be labeled.

Muscles and organs derive the most benefit from the blood that flows in the arteries and capillaries because they obtain food substances and oxygen while releasing wastes.
