The text points out a common misconception about the term "controlled experiment". in the snake mimicry experiment, what factors were held constant?

The factors that were held constant in the said snake mimicry experiment is the one variable being tested. The number of snakes and the species of snakes.

Thus, the answer is:

the one variable being tested, the number of snakes, and the species of snakes.

Everything in the experiment has to be controlled, except for the dependent variable. The independent variable and the number and species of the snakes also needs to be held constant.

EXPLANATION

A controlled experiment refers to a scientific test that the scientist had manipulated. The researcher tests one variable at a time. The independent variable is the variable that is being tested. The independent variables (controlled variables) are seized constantly so that the effects on the subject could be minimized or stabilized.

Biology, as one of the scientific studies, is where controlled experiments conducted. A controlled experiment usually includes limiting the area of the organism that is being studied. This is done to minimize the possibility that other factors can give effects on the research. The other factors can vary, from other variables in the wild, other animals, etc.

There are two kinds of groups in a controlled experiment. One group is called the control group, they do not receive any kind of treatment. Instead, the control group receives the standard environment and conditions. The other group is called the treatment group. The treatment group receives a specific treatment that is usually called the independent variable.  

Control is needed in any kind of experiment. It is to make sure that the experiment is valid and credible, because no other variables interfere with the research. In most fields of study, results and findings can only be accepted if they are statistically significant.  

There are many methods that can be used in an experiment. Researchers can look for the causal relationship between the two variables, the differences between the treatment group and the control group, etc.
