Our lab microscope is parfocal. this means that your lab microscope is parfocal. this means that you can easily discriminate two close objects as separate the slide should be almost in focus when changing to higher magnifications the specimen is clearly in focus at this depth

The correct answer would be the slide should be almost in focus when changing to higher magnifications.

A parfocal lens is a type of lens which stays in focus when focal length or magnification is changed.

Parfocal microscopes are those in which objectives remain in focus even when magnification is changed for example, when it is switched from 10x to 40x, the object or slide remains at the focus.

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.
