An experiment wants to find the wind speed that begins to lift an airplane. the strategy is to use a 1/32 scale model and wind tunnel. why is this strategy valid?
a. a wind tunnel is available for the experiment.
b. the real airplane will not fit in the wind tunnel.
c. the scale model matches the scale of the physical forces in the wind tunnel.
d. an inexpensive scale model of the airplane is available through the local hobby shop.

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.
