If these are the choices:
The ability to halt the cell cycle in response to DNA damage.
The ability to halt the cell cycle in response to the chromosomes not properly aligning on the metaphase plate.
The ability to repair DNA damage.
The ability to activate Cdks.
The ability to stimulate cell death processes if the cell is irreparably damaged.
MY ANSWERS ARE:

Answer:
30
Explanation:
personally i think 40 F, the reason is heat speeds up chemical reactions
The signaling molecule is important, but the receptor it binds to is really what determines what effects it will have on a cell.
Different cells express different receptors. The same signaling molecule could cause very different effects depending on what happens when the receptor is activated by it.
Depends on what you consider "Large". Usually what we consider large amounts, would just make us urinate as it is not water that we need and so would filter it out.
However if you were to say ingest such an amount that it has become toxic, you run the risk of a very dangerous condition called Hyperhydration or Water Intoxication. Under most normal circumstances water and salt are present in cells and the blood. If you remember; water travels through osmosis, or from a higher to lower concentration across a semipermeable membrane. Salt helps to maintain the concentration. However if you drink so much water that it would be considered "toxic" the water that would eventually find it's way into your blood would try to balance with the cells, which begin to absorb so much water that they swell, therefore causing swelling to the body's tissues and organs.
The dangerous bit is when the brain begins to swell. Symptoms such as <span>headache, personality changes, changes in behavior, confusion, irritability, and drowsiness. These are sometimes followed by difficulty breathing during exertion, muscle weakness & pain, twitching, or cramping, nausea, vomiting, and thirst, begin to manifest. The dangerous bit is when the swelling compresses the brain to such a degree it crushes the brain stem and herniates through the foramen magnum. The brain stem or Medulla Oblangata is responsible for the processes keeping you alive, and if it's crushed your heart rate, blood pressure, and breathing will become compromised, a recognizable feature we EMT's look out for called Cushing's Triad. This is mostly irreversible and will lead to neurogenic shock, coma, and then death.
The important lesson, is to always take thing in moderation.</span>
Sea floor sediment provide an invaluable key to past climate change. Finely varved sediments from areas of rapid deposition provide a high-resolution record of past climate variation, and volcanic ash layers contribute to the comprehensive study of climate change on relatively short timescales. Oceanographers like to say that we know more about the dark side of the Moon than we do about the oceans. That statement is doubly true of the seafloor. Although modern technology has allowed us to learn more about the seafloor, vast regions remain unexplored. Scuba divers can only dive to about 40 meters and they cannot stay down there for very long. Although this is good for researching the organisms and ecosystems very near a coast, most oceanic research requires accessing greater depths.
