Describe a plant/ animal in which you can observe wave motion. state the type of wave and describe in relation to body movement

The wavelike motion usually can be described by the equation:

X(y,t) = Acos(kx - wt) + Bsin(kx - wt), so wavelike motion is usually a periodic motion.

Where k is the wavenumber and w is the frequency.

You can see a wavelike motion in trees when the wind moves them and the branches start to move in oscillatory motion.

Another example of wave motion can be some fishes, that use wavelike motion to impulse in the water.

Another example can be the Vipera ammodytes that move in a wavelike motion, with the objective of increasing its speed and agility in the sand.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
