Answer:
meiosis
Explanation:
meiosis occurs in reproductive organs
As continents drift apart, it becomes hard for a population to
mingle freely due to geological separation.
This restricts the gene flow in the once homogenous population hence resulting in the allopatric
speciation of the separated groups of the population. Also, as the continents drift, their climate changes and so does the flora and fauna in the process of
adaptation.
The answer is C. Mollusks. Hope this helps. :)

Explanation:
Answer:
scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.
Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. The three primary methods are:
Radiation Measurement
Stratigraphic Superposition
The Fossil Record
From these methods of dating, scientists have determined that the earth as we know it seems to be about 4.6 billion years old. It is theorized that the earth got its start as a result of what is called the "Big Bang nearly 6 billion years ago. The Big Bang theory holds that all the planets, stars, solar systems, galaxies, etc., are the result of a huge explosion that sent material speeding through space. As time passed, the gravitational force of larger chucks of material attracted the smaller chunks and formed the galaxies and solar systems we see today.
