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.
Answer:
No, I don't agree with the statement that some organelle are not important in the cell.
Explanation:
Every organelle which is present inside the cell is very important because each organelle performs a specific function. Without these organelles, cell cannot perform their functions properly. For example, mitochondria is the power house of the cell which produces energy for the cell. Ribosome is responsible for the production of protein. Lysosomes helps in the removal of waste products from the cell.
The correct answer is the tundra.
The aerobic system of energy production uses glycogen, but primarily glucose as its energy source.
Glucose is taken in by the cell and broken into pyruvate in the process of glycolysis, the first step in aerobic cell respiration. It takes place in the cell cytoplasm.
Pyruvate is then used in the Krebs cycle in the cell mitochondria in the second step of respiration which produces high energy electron carriers. These high energy electron carries such as NADP are then employed in the electron transport chain, the last step of the respiration process, where a large number of ATP molecules is produced.
By the time the process of aerobic respiration ends, 36 to 38 molecules of ATP are produced from one single molecule of glucose.

Volcanoes
Explanation:
Sulfur can be found everywhere but mostly near active volcanoes.
