Solution
The independent variables in an experiment are the factors that are manipulated or changed by the researchers. In the context of Exercise 2: Blood Typing, the independent variables would be:
a) Type of antigen in blood b) Type of antibody in blood
These are the variables that you would change in order to observe the effect on the dependent variable, which in this case could be c) Agglutination.
d) Time and e) Hematocrit level (%) would not be independent variables in this context, as they are not being manipulated by the researchers.
