Need help with background and hypotheses for biology lab report

A. Background Information
The background information of this laboratory report would include information about the slug and the substances that were used in the experiment.  
1.    You should included the following information on the slug.  
        a.    Classification of the organism, including kingdom, phylum, class, order, family and  
               scientific name, if possible.  
        b.    General characteristics of that phylum  
        c.    Related organisms.
        d.    Characteristics specific to the slug, habitats, adaptations, foods it eats, survival  
                mechanisms.  
         e.    Drawings of the slug with labels.  Description of labels, with an emphasis on structures that
                assist in detecting and obtaining food in the environment (nervous, digestion, movement).
                        
2.    You should include the following information on the substances used in the experiment, if possible. You would have to decide what ingredients you wanted to use in the experiment. The laboratory has some substances, but you may want to use other foods or other substances that you may have in your home.  
           a.    Common ingredients in the substance.
           b.    Common uses of the substances  
           c.    Chemical characteristics of the substances, is the substance acidic, basic, harmful, food
                  is it a food source?
B. Purpose
This part of the experiment simply states what you are trying to prove in the experiment.  It is usually only one statement.
C. Hypothesis
These are statements that tell what you think will happen in the experiment.  Remember  
that the hypothesis has inductive reasoning from the initial information you gathered in the  
background information, and then predict what would happen with the knowledge.  For  
example, since vinegar is acidic and acids are usually harmful to organisms (inductive), I  
predict that the slug would not want to be in its presence and would be repelled by it. (prediction-deductive reasoning).  
You have a ten-part hypothesis to this experiment, since you are testing ten substances with the snail. Your laboratory exercise also has a chart that requires you to make separate hypotheses for each substance that you are using.  Make sure all are included in some way in this section.  


Solution Summary

The solution consists of the first part of a lab report on a study that aims to determine which substances will attract or repel a slug.  The background information on the animal and on the substances, as well as the ten hypotheses to be tested, are included.  The results of the study are not included (see posting 118387).
