Systematic observation in field research involves the structured and planned collection of data through direct observation of a specific phenomenon, often using predetermined categories or criteria. On the other hand, participant observation involves the researcher immersing themselves in the social setting being studied, actively participating in the activities and interactions of the group being observed. While systematic observation allows for a more objective and standardized approach to data collection, participant observation provides a deeper understanding of the social context and dynamics by experiencing it firsthand. Ultimately, the main distinction lies in the level of involvement and interaction between the researcher and the subjects of the study. **

Systematic observation in field research involves the structured and predetermined collection of data based on specific variables or behaviors of interest. Researchers use predefined criteria to guide their observations and ensure consistency in data collection. On the other hand, participatory observation involves the researcher immersing themselves in the social setting being studied, actively participating in the activities of the group being observed. This approach allows the researcher to gain a deeper understanding of the context and culture of the group, but may be more subjective and less structured compared to systematic observation. **

Objective criteria in weather observation are measurable and quantifiable factors that are used to describe the current weather conditions. These criteria include temperature, humidity, wind speed and direction, precipitation amount, cloud cover, and atmospheric pressure. By using objective criteria, meteorologists can provide accurate and consistent information about the weather, which is crucial for making informed decisions and predictions. **

Instagram was not deactivated by Instagram. However, there have been instances where Instagram has deactivated or suspended accounts due to violations of their community guidelines, such as posting inappropriate content, engaging in spammy behavior, or violating copyright laws. Instagram takes these actions to maintain a safe and positive environment for its users and to ensure that the platform is used in accordance with its policies. **

No, that is not a satellite space station. A satellite space station is a large spacecraft that orbits the Earth and is used for scientific research or as a base for space exploration. The object in question may be a satellite, but it does not appear to be a space station. It is important to note that without further information or context, it is difficult to definitively identify the object. **

Yes, the weather can affect a military satellite. Extreme weather conditions such as severe storms, high winds, or heavy precipitation can potentially disrupt satellite communications or even damage the satellite itself. Additionally, changes in temperature can impact the performance and functionality of the satellite's components. Therefore, military satellite operators need to consider weather conditions when planning and operating their satellite systems. **

There could be several reasons why your Instagram account was deactivated by Instagram. Some common reasons include violating Instagram's community guidelines, posting inappropriate content, engaging in spammy behavior, or using fake accounts or bots to increase followers. It's important to review Instagram's community guidelines and terms of service to understand what actions may have led to the deactivation of your account. If you believe your account was deactivated in error, you can appeal the decision through Instagram's support channels. **

This is the International Space Station (ISS), a habitable artificial satellite that orbits the Earth. It serves as a space environment research laboratory where scientific research and experiments are conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is a collaborative project involving multiple space agencies, including NASA, Roscosmos, ESA, JAXA, and CSA. It has been continuously inhabited since November 2000 and is a symbol of international cooperation in space exploration. **
