Through a division process called mitosis, eukaryotic cells divide to create new cells. It enables cell replacement after damage or wear-and-tear and also permits growth.
Mitosis is the process of cell division in which the chromosomes replicate and are evenly dispersed into the two daughter cells. It specifically refers to the division of the duplicated genetic material held in the nucleus during cell division. Each daughter cell has the same number of chromosomes as the parent cell, making them diploid. So, meiosis is the process where a single cell divides twice to produce four cells with half the original amount of genetic material. Mitosis is known as equational division. These cells are our sex cells, producing sperm in males and eggs in females throughout the process of mitosis. Eukaryotic cells go through the nuclear division process known as mitosis when they divide to produce two identical daughter cells.

Answer:
Scientists began to mark division on the geologic time scale when patterns and similarities started emerging from archeological studies. Patterns such as the discovery of fossils that were formed within the same period.
Explanation:
Geologists who study matter that make up the Earth's crust (whether solid gaseous or liquid), as well as matter from other terrestrial planets and the processes that influence the formation and condition of this matter, are called geologists.
They have successfully calibrated history into various phases of time intervals. These intervals are event-based intervals. For example, you have Eons, Eras, and Periods.
An Eon is a billion years. An example is the Neoproterozoid Eon. Eons are made up of several Eras and Eras are made up of periods. An example of an era is the Mesozoic era. Whilst periods are smaller units of an era, eg. Triassic era.
As scientists deduced the causes for the formation of fossils and topographical remains/patterns, they collected events that occurred within the same time period and group them together.
This range of events became known as the geological time scale.
The age of fossils and rocks is also used to map out the calibrations on the scale.
The age of fossils and rocks is determined using the process of radioactive dating.
