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. It is the SI unit of frequency, equal to one cycle per second.

Answer:
Option D is the correct option. All of the cells in the embryo would be capable of attaching to one another regardless of the cell type.
Explanation:
Cadherins are molecules that allow cell adhesions. Various number of cells bind together using this molecule for proper functioning.
If all the cells in a frog embryo expressed the same kind of cadherin molecule then all the cells in the embryo would adhere together. Neither will the embryo be able to develop properly nor will it have a proper structure. Most probably, it would lead to the death of the embryo.
