Cancer cells are cells that basically bypass any sort of regulatory processes in the cell cycle (and mitosis - the splitting of the cell). This leads to uncontrollable cell growth/duplication which hence leads to more and more cancerous cells. Cancer itself is so hard to cure for a couple of different reasons. If the cells are in the form of a benign tumor, that is a tumor that does not spread from its original infected tissue, it should be "easy" to remove with surgery. However, if it metastasizes, or spreads into surrounding tissues through the lymph or blood systems, then it becomes even harder to remove because of its far reach and complex structure. Also, cancer cells can be simply described as normal body cells that have gone rogue. That being said, things such as antibiotics, that are designed to get rid of foreign bodies, cannot get rid of cancerous cells without getting rid of most of your regular body cells as well simply because they cannot tell the difference.
Hope this helps :)
Answer:
The correct answer is: A) the Calvin Cycle alone.
Explanation:
These reactions happen in cells capable of photosynthesis.
The only out of these reactions that require CO2 to take place is the Calvin Cycle. The Calvin Cycle is a series of biochemical processes that occur in the chloroplasts during photosynthesis. <u>The Calvin Cycle uses carbon dioxide (CO2) and water to produce glucose</u>, which will give energy to the cells.
The light reactions occur during photosynthesis in the presence of light and involving photophosphorylation. The light reaction does not make use of CO2, as it takes solar energy and converts it into NADPH and ATP.
The element is Manganese. Period I believe is boiling point and group is melting point.
First of all, the cohesive and adhesive properties of the water molecules fascilitate this. Water molecules stick together and with the walls of the vessels, creating a column of water which doesn t break easily. Moreover the xylem vessels of the tree are very narrow increasing the pressure. Finally, transpiration is taking place as water from the leaves evaporate, thus a continuous osmotic gradient is being created, causing water to be drawn up the tree
