Answer: When Rome fell entered a new time period that lasted a long time, this period was called the Dark Ages. Dark Ages is believed by many to be an awful time in history. The fall of Rome affected many people's daily lives. When Rome was pretty much it officially fell in 410. Rome brought so many civilizations together when it fell its citizens didn't know what to do. People who lived in cities fled their homes for the countryside in hope for protection while Rome was being raided; they later became serfs and peasants and worked for the landlord. People who already lived on the land had to defend for themselves, the Romans system of running water had already stopped, and life was harder to live than when the Romans were in control. Roman buildings were crumbling down to the ground and their remains were being used to make shacks. People were starving, illness was spreading, and people were dying, this went on for a couple hundred years. This time in Europe was truly dark in the beginning, but over time it grew into a lighter life. In this time castles were being built for protection from the many wars the new small kingdoms were making. After a couple years, feudalism had begun, and order was starting to be put in these countries. In these small kingdoms Christianity was the main religion

Hello. This question is incomplete. The full question is:
"Dr. Parrett is a sports psychologist for a large Southern university. The provost and chancellor have asked him to examine the relationship between athletic performance and academic stress at the university. For example, is it the case that the most talented athletes experience the greatest concern over their grades? The provost and chancellor have made it clear to Dr. Parrett that they want a large amount of external validity in the study. He has valid and reliable measures of both athletic performance and academic stress. He knows that he does not have the time or the money to study the entire population of interest.
Imagine that Dr. Parrett wants to use a nonrepresentative sampling technique. Name the three types of nonprobability sampling and explain how each one could be used by Dr. Parrett."
Answer:
The four types of nonprobability sampling are convenience sampling, purposive sampling, quota sampling, and snowball sampling.
Explanation:
Convenience sampling: Allows a selection to be made of a small sample of the target population of the research. This sample is made up of individuals who are available and accessible to research and not through statistical criteria. Regarding the question above, Dr. Parrett can select the athletes he knows and who would like to participate in the research.
Purposive sampling: It allows the sample to be controlled whenever a certain manipulation is possible to generate expected and known results. In the case of the question above, Dr Parrett can search for specific athletes, with characteristics that will generate an expected result in the research.
Snowball sampling: Allows the individuals who make up the sample to invite other individuals to compose the sample, who in turn can invite other individuals. In the case of the question above, Dr. Parret can invite the athletes he wants and ask them to call friends to participate in the survey as well.
Sampling quota: Allows the individuals who will compose the sample to be selected due to their characteristics and qualities. Regarding the question above, Dr. Parrett could only summon athletes with high marks.
Answer: C. A species is brought to a new environment where it has no predators.
Explanation:
According to the <em>Green Invaders</em> article, invasive species are plant species that people brought with them when they moved to the United States because they wanted to make the vegetation more aesthetically pleasing.
The article mentioned how this could be bad for the ecosystem however because most insects are plant specific which means that they only feed on certain plants and without those plants, they could die off.
The insects are the predators for plants therefore and if they are unable to eat these new invasive plant species then that means that these plant species are now in an environment where they have no predators.
