Star clusters are groups of stars which are gravitation-ally bound. Two distinct types of star cluster can be distinguished: globular clusters are tight groups of hundreds of thousands of very old stars, while open clusters generally contain less than a few hundred members, and are often very young.
Binary system: a system in which information can be expressed by combinations of the digits 0 and 1. to represent codes and data. Since zeros and ones can be easily represented by two voltages, the binary system is the foundation on which digital technology is built. Every digital computer whether a pocket calculator or a mainframe uses the same binary notation.
I believe the answer to your question is C
Answer:
- interactions between group members
- interactions with people outside of the group
- interactions with the environment
Explanation:
The culture is the most powerful tool of any society. It is unique to each group, and it is what defines that group of people. The culture has the ability to shape up three types of interactions:
- interactions between group members
- interactions with people outside of the group
- interactions with the environment
The interactions between the group members are good in general, as they belong to the same culture and have lot of similarities. An example can be the interaction between two neighbors.
The interaction with people outside of the group can go either way though. If there are some similarities between the cultures then the people will most probably become close, but if there are big differences, it will most probably cause conflict. An example can be the interaction between a Catholic Mexican and Muslim Arab.
The interaction with the environment is crucial for any culture, and every culture has special and different interaction with it, depending on its characteristics. An example of this can be that the Celtic people considered the trees to sacred, and some trees such as the willow for forbidden for cutting as it was of highest rank.
The surface of the Earth, or more specifically the mountain side that has been covered with ice that over time will expand more and more, will change in shape significantly over longer period of time.
The change will be manifested in the mountain side becoming very steep, sharp, pointy, looking, and that will be due to the erosion caused by the ice on it, which essentially will a glacial erosion, since that ice will be a glacier on the mountain side.
The change in the landscape will be seen only after the glacier melts and uncovers its effect, but while the mountain side is covered with it, it will not be easy to witness the change.
