- The sporophyte stage is the diploid stage (2n) where fertilization occurs.
Answer:
The correct option is C. <u>The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the
</u>
<u>inhibitor.</u>
Explanation:
Glioblastoma can be described as a kind of cancer or tumour of the brain. Astrocytes are the cells which cause this condition. Glioblastoma is one of the most deadliest kinds of cancer. As astrocytes have contact with numerous neurons from the body hence a cancer in these cells can be very toxic.
Scientists have been working hard to find a treatment for this type of cancer.
In the experiment described above, the scientists have found out that an inhibitor present in the umbilical cord cells can stop cancer cell proliferation. Hence, they have derived a test culture where the glioblastoma cells were treated with this inhibitor molecule. The control group glioblastoma cells were not treated with this inhibitor.
