Answer:
c. wtih physically differing populations which can still successfully reproduce
Explanation:
Polytype is when a single species has many variations in its area of coverage, it is thought that they are distinct species, or when many varieties or breeds of the same species are produced, as in the Lobos, which is naturally already polypic, and many dog breeds are still bred within the subspecies Canis lupus familiaris. In other words, we can say that in a polytyp species, many individuals have very different physical characteristics, but are of the same species, so they can reproduce successfully.

Explanation:

Answer:
As the cell grows, it faces some issues such as:
• Running out of the nutrients and requirement of growth factors.
• Running out of the space.
• Require appropriate gas exchange.
As compared to the smaller cells, larger cells have more issues in moving the required materials inside and excretory products outside. This is because the ratio of the surface is to volume is turning more and more unbalanced and takes much longer time for the cellular processes to take place.
