Hypothesis: certain salinity levels may have an effect on the # of naupli and eggs hatched of copepods in its environment.

I will attach the paper that was originally written so you have something to go off of, and the corrections to be made also following these instructions below.
Overview
The revised introduction is an improved version of the first draft, based on comments from your instructor. It should have the following sections:
Title Page and Authors
Include your group name
Include each member’s name and role in the project
The title of your project should be concise but also needs to be specific enough to convey the information in the study. For example “temperature and copepods” is too vague but “the effect of changing temperature from 10-20 degrees daily on the survival, growth rate, and egg production of all life cycle stages of the copepod Tigriopus californicus” is too long!
NOTE: Species names are binominal; the first word is the genus name and is always capitalized, the second word is the specific epithet and is never capitalized – the combination of both words is the species name. Thus, a species name should always be written out in full and italicized [e.g., Tigriopus californicus] the first time indicated in a section. After that it can be shortened to T. californicus.
Never write the just the species epithet “californicus” . . . or it could be confused with Myotis californicus [a California bat] or Microtus californicus [a California vole]!
Species names should not be used as adjectives [eggs of T. californicus not T. californicus eggs] or with possessive [reproduction of T. californicus not T. californicus’ reproduction].
Introduction
This is where you want to bring in the background information [from the primary literature] for your research topic and explain your specific research question. You will need to explain a bit about copepods and then the research that has been conducted on the variable you are testing. You also need to explain why any of this matters – i.e., why bother to answer the question you are asking. You will present the hypothesis that you will test.
References
You will need to include all of the references that you cited, and these must be in the proper format [see examples below]. You must have at least 3 primary research article references in the Introduction. Do not list any references that are not cited in the paper, and do not cite any that are not listed in the references!
