Stuxnet virus is a malicious computer worm which was discovered for the first time in 2010. Stuxnet is used to target SCADA [Supervisory Control And Data Acquisition] system. It was the one that is responsible for the serious damage to the Iran nuclear power.
People are needed on ground for the stuxnet virus to work because, the virus requires a physical implantation in order to work. Such people are usually expert in detecting the most vulnerable spots in a system.
The best answer for this question would be:
Cesarean birth

Cleavage as part of embryonic development is idiosyncratic since it involves the cell division which includes the process of mitosis with minimal or no growth in successive divisions. Hope this is right and the correct answer you are looking for.
Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.
Further Explanation:
In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.
CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.
Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.
