Most animals begin their lives as a single, microscopic cell called a zygote. this begins a series of countless cell divisions, eventually resulting in a large, complex organism. which type of cell division is used for this process?

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

the question isn't complete here so i can't right an answer '_'
