Dust is a mixture of different things, that is the reason that can posses charge.

Dust particles do not have charge in it, it is the charge of the substance that is attached to it that can flow the charge to the dust.

Explanation:

When the dust particle is attached to a charged substance it possess charge. The charge of the substance make the dust particles polarize to make it charged.

For example, when the dust particles sticks to a tv screen then it is not the dust charge that make it stick to the screen, it is the charge of the tv screen that make the particles attached to it.

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.
