Answer:
reduced biodiversity
Explanation:
Biodiversity is the variation of plants and animal on earth. Biodiversity involves all creatures in the ecosystem. it consist both terrestrial and aquatic creatures. The richness in variability of life contribute immensely to the ecosystem because each life plays a major and vital role to the ecosystem.
Increased population will invariably affects the biodiversity of a region because more food and other raw material will be source thereby altering the well being of other species in the ecosystem that depend on the raw material.
Example the population explosion of human has bring about increase in fuel consumption. This will cause more involvement of expertise to drill the crude oil to meet the population demand. Through active crude exploration more life in the marine are affected causing unbalance in biodiversity. That is the biodiversity of aquatic life will be reduced when more crude oil find it way to the sea.
Because the banks had closed down and they had know way to get what they needed.
Industrialization in the US made Americans consumers as hey would rely more and more on what was produced from this new method. Businesses grew, which helped the spread of industrialization to start.

The businesses, country, and citizens were in some ways consumers to industrialization in the late 19th century.
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.
