Higher concentration of salt. 1. Inhibits nucleic acids secondary structure formation by increasing repulsion of phosphodiester backbones. 2. Will have no effect on nucleic acids secondary structure formation. 3. Promotes nucleic acids secondary structure formation by decreasing repulsion of phosphodiester backbones. 4. Affects nucleic acids secondary structure formation by changing the strength of stacking interactions.

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.
