If we add the hydrogen peroxide with a graduated cylinder that had vinegar in it the sample could get contaminated with an acid or base oil or all of the above

The correct answer is acid.

Explanation:

The sample would get adulterated with acid. This is due to the fact that vinegar is an acid. Application of a graduated cylinder, which possesses vinegar in it will infect the sample with an acid and the chemical reaction that the hydrogen peroxide is considered to be used for will be influenced negatively as a consequence of this adulteration.

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.
