Cell division occurs in all living organisms. This is known as mitosis.
The advantages of a larger organisms to subdivide themselves into smaller cells is that as all organisms grow, some of their cells die or get damaged with time and need replacements. So,it divides into smaller cells because when a cell becomes large, it demands more of cell places of its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. So to grow properly the cells need to be divided.

Answer:
The options
A. the postzygotic barrier called hybrid inviability
B. the postzygotic barrier called hybrid breakdown
C. the prezygotic barrier called hybrid sterility
D. gametic isolation
The CORRECT ANSWER IS A.
A. the postzygotic barrier called hybrid inviability
Explanation:
Postzygotic barrier is a mechanism that hinders reproduction after fertilization and zygote development. Hybrid inviability occurs when a mating between two organism produces a hybrid that can't strive past the embryonic stages.
In Reduced Hybrid Viability there is a lower tendency to survive for individuals whose parents possesses incompatible genetics, which may have result from sexual union of these parents from varying species.
These two frog species in this case study can be separated through the mechanism of the postzygotic barrier called hybrid inviability.
