What is the purpose of a thesis statement?
A thesis statement, usually placed at the end of your paper's introduction, is meant to encompass the entire purpose and main argument(s) of your paper. It should not be extremely long or detailed; the details are saved for the following paragraphs. The statement should simply state the content and ultimate argument of your paper.
What does "carrying capacity" mean and what does it explain about how populations function in a given habitat?
Carrying capacity refers to the maximum number of individuals of any given species that a certain area can sustain on a long-term basis. This limit is determined by the amount of resources available in the area to support that particular species. If the population of a species were to increase above the carrying capacity, there would no longer be sufficient resources, causing the population to die off until it is once again below the carrying capacity. For example, if a small island contains a species of parrot, and the carrying capacity of that island for the parrots is known to be 200 individuals, then that means the island does not contain enough resources (food, living space, etc.) to support significantly more than 200 parrots. If, for example, a sudden reproductive boom results in a population of 250 parrots in one generation, the population size would exceed the available resources--there would no longer be enough food and living/nesting space for all of the parrots. Thus, they would begin to die off, and soon the population would once again be at or below the carrying capacity.
How does one know when to use a semicolon?
A semicolon should be used when you want to separate two or more clauses of a sentence, especially if there is a transition word/phrase between them (e.g. however, or, as a result, furthermore, etc.). It can also separate parts of a sentence decribing different aspects of one concept. For example: "Some people enjoy cooking every day; others prefer the practicality of frozen meals." You can think of a semicolon as a halfway point between a period and a comma. Periods can separate unrelated sentences; commas can separate words and clauses that are all part of the same sentence; and semicolons can separate independent but related clauses of a sentence, such as the three in this very sentence. In contrast, a colon is used to precede a list within a sentence, or a bulleted/numbered list that follows a sentence. For example: "I have two dogs: a Dalmatian named Pepper, and a terrier named Rascal." A colon cannot separate related clauses within a sentence the way a semicolon can. Furthermore, the part of the sentence preceding the colon must be a complete sentence that could stand on its own (e.g. "I have two dogs" is a functional sentence without the additional information after the colon).
