Answer: cold and warm air masses interact in an unstable environment.
Explanation: Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone .According to the polar-front theory, extratropical cyclones develop when a wave forms on a frontal surface separating a warm air mass from a cold air mass. As the amplitude of the wave increases, the pressure at the centre of disturbance falls, eventually intensifying to the point at which a cyclonic circulation begins. The decay of such a system results when the cold air from the north in the Northern Hemisphere, or from the south in the Southern Hemisphere, on the western side of such a cyclone sweeps under all of the warm tropical air of the system so that the entire cyclone is composed of the cold air mass. This action is known as occlusion.Extratropical cyclones arise through a process called cyclogenesis, in which cold and warm air masses interact in an unstable environment.
The sources of pressure are from:
Regulation -government and legislative changes that focus on promoting environmental changes
Resources -natural and other resources are limited and conservation will help save money
Social/reputation-being environmentally conscious gives customers positive feelings about a company

Answer:
The answer is: letter a, To protect national security.
Explanation:
This incident occurred in <em>2016.</em> Taobao is one of the online shopping websites owned by "Alibaba Group." It was placed on the blacklist by the U.S. because of selling<em> "counterfeit goods."</em> However, it was removed from the blacklist in 2012, since it showed efforts in combating piracy.
One reason for putting Taobao in the blacklist is to protect national security. This is the responsibility of the government to the nation when it feels threatened by anything harmful. The pirated goods were considered a threat to the nation. It can also result to financial loss to the owners due to stolen intellectual properties.
Thus, this explains the answer.
Robert should use intermittent schedules of reinforcement to keep his employees mentally alert and interested. The procedure of learning through association to increase or decrease voluntary behavior using punishment and reinforcement is known as operant conditioning.
Reinforcement schedules are the rules that govern the timing and frequency of reinforcer delivery in order to increase the likelihood that a target behavior will occur again, strengthen, or continue. A contingency timetable is one that includes reinforcement. While intermittent schedules provide reinforcers.
After some but not all correct replies, intermittent schedules apply reinforcement after each correct response, or none at all. Reinforcers are only used after the target behavior has occurred, so reinforcement is conditional on the desired behavior.
