Blastulation is the process of the cleavage subdividing the mass of the zygote until a cluster of cells known as blastula are formed

Blastulation is when the cells move to form a hollow "ball". Gastrulation is when it bends upon itself to make 3 layers, called the endoderm, the mesoderm, and the ectoderm.

After he formation of morula(in cleavage),a number of changes occur which lead to blastulation.A cavity appears due to compact rearrangement of of cells in embryo within the upper half,now called blasocoel.The embryo now called blastula.The cells now move to new positions according to function they have to perform.
Metamorphosis is the change of form such as that occurs when a tadpole changes into a frog.
blastulation
The frog is in an egg, then the egg hatches to form a tadpole. The tadpole grows back legs, then front flippers. Finally, metamorphosis occurs, and voila! Adult frog.
the stages of growth are: gametogenesis fertilization cleavage or segmentation blastulation gastrulation organogenesis
Bacterial infection of the hoof, which primarily occurs in the frog of the hoof, not the actual hoof.
A black substance around the frog is often thrush. Thrush is a disease that usually occurs because the horse is living in filth or a dirty stall for long periods.
The tadpole is the stage in which most growth occurs. This is the stage when back legs are front legs are grown.
