Answer:
Hello!
7. A totipotent stem cell is a cell capable of differentiating into any cell required by the body.
A pluripotent stem cell can differentiate into any body cell but it is not required for the growth and development of the embryo.
Multipotent stem cells can differentiate into any cell in a specific cell lineage. For example, a red blood cell or white blood cell.
An oligopotent stem cell can differentiate into one of a specific cell type.
A unipotent cell is fully differentiated and specialized and can only produce more of its own cell type.
5. True. Tissues are a group of cells with the same structure and function.
Explanation:
Stem Cells:
A stem cell is an undifferentiated cell that has the capacity to differentiate into any cell of the body under specific conditions.
- Totipotent stem cells are the first embryonic cells produced by the division of the zygote. They can differentiate into any cell required for development.
- The embryonic cells formed through the division of the zygote are pluripotent cells.
Gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote.
Answer:
b
Explanation:
half of the original c-14 isotope remain in the fossil 5730 years after the organisms died. 1/4 of the original isotope will remain 5730 years after that or 11460 years after the organism died.
