Answer:
I am pretty sure that the answer is A.
Explanation:
Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.
I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or growth factors (not in the answer choices). Since one of the factors that leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!

Using less water is one way to practice water conservation
Answer:
The correct answer is the letter D. decreasing the moisture content of the air and increasing temperature
Explanation:
Fog is the result of air humidity, or water vapor in the atmosphere. The mist that forms in the morning is the result of water that changes from a gaseous to a liquid state. It is characterized by a cluster of water droplets, which give rise to a type of cloud that is very close to the Earth's surface arising from the cooling of the air during the night. Thus, it is formed by the suspension of water droplets in an air layer close to the ground. Thus, fog can be considered a cloud that comes into contact with the ground.
