BRAINLIEST TO BEST ANSWER!! The study of Escherichia coli (E. coli) led researchers to new experimental designs for studying operons. Which experimental design did the scientists use?

A. Use a microscope to observe cell division to determine the structure of operons.

B. Test the response of E. coli to a variety of chemicals to determine the number of operons that are present.

C. Insert the operons from one organism into another to determine the mechanism of operon expression.

D. Read the genome sequence to determine the quantity and organization of operons.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
