Answer:
B) a college environmental club cleaning up the shoulder of a highway
Explanation:
Ecosystem service are the services rendered in the favor of our ecosystem and environment. This benefits the surrounding environment which in turn benefits us in the latter stage.
So everybody in the society should work for a clean and pollution free environment and should run awareness programmes to educate the people about the benefits of a healthy and pollution free ecosystem.
So the best example of an ecosystem service will be when a team from college environmental club cleaning the shoulder of a highway shows ecosystem service.
Hence the answer is
B) a college environmental club cleaning up the shoulder of a highway
Answer:
Cultural diffusion. See my explanation

The greeks were heavily divided amongst city-states, such as Sparta, and Athens. After the Persian Empire invaded, the Greeks saw things in a new light. They grouped together and fought. They were defeated, but later reclaimed Greece. While occupied by the Persians, they learned new things about tools and weapons. The Persians did not however force their own idealogies and religious beliefs on the greeks.
Answer:
Repeated measures design.
Explanation:
Repeated measures design: The repeated measure design refers to a research design involving various or multiple measures consisting of the same variables taken on the matched or similar subjects either over two or more times or consisting of different conditions.
Example: A researcher conducting a longitudinal study takes repeated measurements of an individual or a group of individuals over time.
In the question above, the procedure of the study represents the repeated measure design.
Answer:
a. The condition in which the individual is isolated and divorced from his or her society, work, or sense of self.
Explanation:
Alienation -
It refers to the situation of loneliness , where the person is isolated in the society , is referred to as alienation .
The person might be separated from family friends and even work , and hence , becomes depressed and isolated .
The condition is very depressing and frustrating .
Hence , from the question ,
The correct option is a.
A mutation is the change in the sequence of a nucleotide or in the organization of the DNA (genotype) of a living being, which produces a variation in the characteristics of this and that is not necessarily transmitted to the offspring. It occurs spontaneously and suddenly or by the action of mutagens. This change will be present in a small proportion of the population (variant) or of the organism (mutation). The genetic unit capable of mutating is the gene, the unit of hereditary information that is part of DNA.
In multicellular beings, mutations can only be inherited when they affect the reproductive cells. A consequence of mutations can be, for example, a genetic disease. However, although in the short term they may seem harmful, mutations are essential for our long-term existence. Without mutation there would be no change, and without change life could not evolve.
The definition of mutation from the knowledge that the hereditary material is DNA and the proposal of the double helix to explain the structure of the hereditary material (Watson and Crick, 1953), would be that a mutation is any change in the sequence of nucleotides of DNA. When this mutation affects a single gene, it is called a gene mutation. When it is the structure of one or more chromosomes that is affected, chromosomal mutation. And when one or several mutations cause alterations in the whole genome they are called genomic mutations.
