Answer:
In Amoeba and Paramoecium, osmoregulation occurs through contractile vacoule. Osmoregulation is a phenomenon in which contractile vacuole plays an important role in maintaining the water balance of the cell. Paramoecium contains two contractile vacuoles which have fixed position.
Wavelength
It is the distance between successive crests of a wave, especially points in a soundwave or electromagnetic wave. Frequency is the rate at which the it is repeated over a particular period of time. Trough is the level at which the wave has the highest point. Crest on the other hand is the opposite of trough it is the lowest point of wave. The unit of frequency is the Hertz.

Explanation:
Polygenic trait is trait that is controlled by more than one gene. This is different than Mendelian genetics in which one gene controls one trait (e.g. flower color). Expressed phenotype is mix of all genes that control it (each gene has the same influence on phenotype).
Traits that are polygenic are height, skin and hair color, intelligence etc.
