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:
The five-and-five first aid action recommended by the red cross
Explanation:
When an infant is choking and becomes unresponsive, the five-and-five approach is recommended as a first aid treatment to dislodge the material blocking the airway.
<em>The five-and-five action involves alternation between giving the subject five back blows and five abdominal thrusts until the the choking material is dislodged or the subject becomes unconscious.</em>
If the infant becomes unconscious, CPR should be performed and further help should be sought.
I believe the answer is B. Hope I help! Sorry if not. ):)
