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!
Answer:
D
Explanation:
Water and air circulate around the world in water currents and wind systems (like prevailing winds) respectively, hence distribute energy and whatever else they are carrying across the globe. This is why polluting the oceans in the equatorial region will have indirect consequences for marine life in the poles.
Pollution of air through emission of greenhouse gases in one part of the globe will contribute to global warming across the world because these emissions will be carried around by prevailing winds and diffuse across the atmosphere.
Global warming also causes climate change that subsequently causes the displacement or migration of organisms when this change in climate is unfavorable
