Which description distinguishes the process of meiosis from mitosis?
-Unlike mitotic cells, meiotic cells undergo a single division to halve their chromosome number,
after which they undergo crossing over to restore their diploid state

-Unlike mitotic cells, meiotic cells undergo multiple divisions to produce an effectively unlimited
array of daughter cells which are genetically identical to the parent cells.

-Unlike mitotic cells, meiotic cells undergo pairing of homologous chromosomes, allowing
centromeres to remain intact throughout both cellular divisions.

-Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for
genetic diversity in sexually reproducing organisms.

Unlike mitotic cells, meiotic cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.

Explanation:

Both meiosis and mitosis are types of cell division. However, unlike mitosis that occur at one division only and yield two daughter cells with diploid number; meiosis involves two division steps:

- Meiosis I

where the parent cell is halved in chromosome number, and genetic materials are mixed between chromatids

-Meiosis II

where the two daughter cells generated in meiosis I is further divided into four haploid cells.

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
