a. The chromosomes in a somatic cell of any organism are all morphologically alike FALSE

Somatic cells have autosomal chromosomes and also carry sex chromosomes. These chromosomes are in pairs and each pair is morphologically different from the other pairs because they have differences in the size and the position of the center. It allows them to be differentiated from others, this can be made evident by a karyotype.

b. During mitosis, the chromosomes divide and the resulting sister chromatids separate at anaphase, ending up in two nuclei, each of which has the same number of chromosomes as the parental cell. TRUE

During the anaphase there is separation of the sister chromatids. At the end of the anaphase, a complete set of chromosomes is grouped at the cell's poles. The mitosis process produces two daughter cells with the same genetic material to the progenitor cell.
