How to cells undergo differentiation to form the numerous types of cells in the body?

The stem cells that are initially formed in the  body undergo differentiation through various chemical signals that drive them to differentiate into appropriate cell types.

Explanation:

The two haploid gelametic cells fuse to form a diploid cell which is got as a zygote. This zygote is a simple cell that undergoes repeated mitotic divisions to form different cellular organelles.

The cells that are differentiated into a particular type thereby they are differentiate into different organ systems according to the chemical signals that are received by the receptors of the cell.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
