The cell cycle is a series of developmental phases or activities that occur in a cell which results in its division, and replication of its DNA (deoxyribonucleic acid) to produce two new daughter cells in a process known as reproduction. Cells carryout the activities of the cell cycle in an orderly, predictable series of steps, and after the completion of the cell cycle, it returns to its beginning and then repeats itself in the same sequence. In eukaryotic cells (cells that has a true nucleus), the steps of the cell cycle is grouped into two major phases which are; interphase and the mitotic phase.

How do geologic timelines help scientists?

Otrada [13]

Answer:

They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened. The geologic time scale is divided into eons, eras, periods, and epochs.

Colt1911 [192]

Answer:

Membrane bound cell organelles

Explanation:

A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.

To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.
