Answer - Purpose of the cell cycle is generally replicate and split itself thru mitosis and its stages to make more cells.
Reason - Cell cycle is generally important to all organisms because it helps develop and keep things going. Such as a T-Cell which is white blood cell that help protect us from virus/bacteria. Or Brain cells which helps neurons with chemical nerves and maintain it. Or stem cells that can be replicated into any as mention or more.

The running out of the nuclear energy from the star indicates that the star is about to die and it can die in so many ways. The Supernova explosion is one way that the star might die, triggering the beginning of a new star's life cyce. The Supernova is said to be the greatest explosion that can happen in space.
Answer:
C. Joining of self-replication molecules into protocells.
Explanation:
For the origin of life, at least three conditions are needed.
- there must have been a supply of replicators, that is, self-replicating molecules.
- copying of these replicators must have been subject to error through mutation.
- the system of replicators must have required a continuous supply of free energy and partial isolation from the general environment.
The radiation received from the sun on the early earth must have fulfilled the requirement of mutation. The mutation is necessary for bringing variation in the genetic material thus driving evolution. To protect the self-replicating molecules from the external environment and to keep them together, the molecules must have been enclosed in a membrane barrier, which should be selectively semipermeable, to facilitate the exchange of molecules.
