1. what are the three stages

in the life of a cell?

what is the cell cycle?
the three stages of the life of a cell together are called the cell
cycle. these three stages are:

• interphase: this stage makes up most of the life of the

cell. during interphase, cells grow and carry out their life
functions. in cells that will divide, the nucleus makes a
copy of its dna in a process called replication.

• mitosis: during this stage, the nucleus of the cell divides

into two equal and identical parts. each part has a copy of
the dna.

• cytokinesis: during this stage, the two equal, identical parts

of the cell separate. the result of this stage is two identical
cells, each with a nucleus and dna.

Explanation:

To answer the question "What are the three stages in the life of a cell?", we refer to the text under "What is the cell cycle?". It clearly lists the three stages of the cell cycle (which are the three stages in the life of a cell) as interphase, mitosis, and cytokinesis. Each stage is described with its functions: interphase involves growth, cell activity, and DNA replication; mitosis is the division of the nucleus into two identical parts with DNA copies; cytokinesis is the separation of the two cell parts to form two identical cells.

Answer:

The three stages in the life of a cell are interphase, mitosis, and cytokinesis.
