To determine whether eating sweet snacks (e. g. candy) causes more weight gain than eating oily snacks (e. g. potato chips), you feed two different groups of mice 1g of either candy or potato chips each day for seven days, and you compare the starting weight of each group with the final weight after the week. Identify the following elements of your snack experiment:

a. iIndependent variable:
b. Dependent variable:
c. Control treatment(s):
d. Experimental treatment(s)
e. Standardized variables:

a. the independent variable is the type of food you are giving the mice.

b. the dependent variable is the final weight of each group of mice.

c. the control is the amount of food you give to the mice.

d. the experimental treatment is what you are doing (which is feeding the mice two types of food to see which one causes more weight gain).

e. the standardized variable is the amount of time you are feeding the mice for (seven days for both groups)

Explanation:

I hope this helps ! :)

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
