Answer:

reduction in birds skeleton

Explanation:

The reduction in a bird's skeletal weight is largely a result of hollow construction of the skeleton. The fusion or loss of individual bones reduces the number of movable joints in the bird's skeleton, making it rigid and better adapted as the internal framework of a flying machine.

Options for the question are not given. They are as follows:

sublimation

condensation

deposition

evaporation

melting

Answer:

sublimation

Explanation:

When a matter changes its state directly from solid to gaseous without encountering the liquid phase, the phenomenon is called as sublimation. It can be observed in places which have below freezing temperature, dry winds and sunlight. Dry air with less relative humidity leads to direct conversion of snow into vapor. Heat required is supplied by the sunlight. Since here the clothes first froze and then directly dried in the above mentioned environmental conditions, it is a case of sublimation change of state.
