Answer;
C. Multipotent
Explanation;
-Multipotent cells are those cells that can develop into more than one cell type, however, they are more limited than pluripotent cells. Adult stem cells and cord blood stem cells are considered multipotent.
Totipotent cells on the other hand, are those cells that can form all the cell types in a body, together with the extraembryonic, or placental cells. Embryonic cells are the only cells that are totipotent within the first couple of cell divisions after fertilization.
Pluripotent cells are those cells that give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.
Answer:
Option D, a test for the presence of cells that contain DNA
Explanation:
As we know all living organisms are made up of cells and DNA is the basic genetic material that codes for protein and traits with an organism. If even a single cell with DNA is detected on the extraterrestrial planet then it will be clear that it has life on it or the environmental conditions are favorable to support life. Cells are microscopic and hence can be seen through microscope which can be installed easily on a probe.
Hence, option D is correct
Answer:
1/2 wWBb , White wool and brown eyes.
1/2 wWbb , White wool and blue eyes.
Explanation:
White wool (W) is dominant over black wool (w).
Brown eyes (B) is dominant over blue eyes (b).
A sheep with black wool (ww) and brown eyes (Bb) is crossed with a sheep with white wool (WW) and blue eyes (bb).
<h3>wwBb x WWbb</h3>
If there is independent assortment between genes, the genotypes of the first parent's gametes will be wB and wb. The gametes of the second parent can only be Wb.
<u>The resulting offspring will be:</u>
- 1/2 wWBb , White wool and brown eyes.
- 1/2 wWbb , White wool and blue eyes.
