Answer:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion
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.
It means that the atom or the group of atoms became positive ion by losing two electrons Ex.
