Contain a complete set of all DNA (46 chromosomes in humans).
-
Exist only in embryos.
-
Can form other kinds of cells.
-
Remain within the bone marrow.
Correct Answer
A. Can form other kinds of cells.Explanation
Stem cells are unique because they have the ability to differentiate and develop into various types of cells in the body. Unlike other body cells that have a specific function and cannot change, stem cells can give rise to specialized cells such as muscle cells, nerve cells, or blood cells. This characteristic of being able to form different types of cells is what sets stem cells apart from other body cells.Rate this question:

The products of meiosis from one parent cell are
-
Two diploid cells.
-
Four chromosome pairs.
-
Four haploid cells.
-
Two haploid cells.
Correct Answer
A. Four haploid cells.Explanation
During meiosis, a type of cell division that occurs in the reproductive cells, one parent cell produces four haploid cells. Haploid cells contain half the number of chromosomes compared to the parent cell. This is achieved through two rounds of cell division, resulting in the formation of four genetically diverse haploid cells, each with a unique combination of chromosomes. Therefore, the correct answer is four haploid cells.Rate this question:
