Answer:a. mitosis
Explanation: mitosis is a type of cell division found in somatic cells.
The daughter cells contains the same number of chromosomes as the parent cell.
Mitosis involves four stages namely;prophase, metaphase, anaphase,telophase.
There is also an interphase,of normal functioning of the cells.
Mitosis is important in asexual reproduction , regeneration and replacement of lost cells.
It also causes growth in organisms.
Unlike meiosis , crossing over does not occur in mitosis thus there is no variation in daughter cells
Answer:
AAATT - TTTAA
CGCAT - GCGTA
GGGAC - CCCTG
ACGGT - TGCCA
Explanation:
In DNA, A and T, also known as adenine and thymine pair together and G and C, also known as guanine and cytosine pair together due to the hydrogen bonds formed between the two bases.

The development of cell theory serves to show the rigorous activities that must be accomplished before a theory can be developed. A scientific theory is a tested and acceptable explanation for a particular observation. A scientific theory usually started as an observation. The observation is use to formulate an hypothesis which is then tested by carrying out an appropriate experiment. If the experiment confirms the hypothesis to be true, then other scientists from different parts of the world will carry out their own experiments in order to confirm the result of the experiment.
When the result of the experiment has been tested continuously for a long time and find to be true, then it becomes a theory. This is the chains of activities which the observations made in cells undergo before it becomes cell theory.
