Answer:
Option A, B, C
Explanation:
A wave’s highest part is called crest and the lowest part is called trough. The vertical length between the highest and lowest part of wave i.e crest and trough is called wave height. Hence option A is correct. Steepness of waves is defined as the ratio of height of wave to its length i.e wavelength. Hence option b is correct
And the steepness of wave should never exceed the ratio of 
, if ration exceeds the wave gets steep and finally breaks down
Hence, Option A, B, C are correct
Answer:
Osmosis
Explanation:
Osmosis is the process of movement of water molecules from the region of its higher concentration (hypotonic) to that of the lower concentration (hypertonic).
Here, two solutions of different solute concentration are separated by a membrane that allows the movement of water molecules through it. Osmosis is a passive movement and does not require an input of energy as it is driven by the concentration gradient.
