The statements that are true regarding a catalyst are as follows:
It undergoes no permanent change during a reaction
It does not participate in a chemical reaction
What is a catalyst?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
A catalyst increases the rate at which a chemical reaction occurs by decreasing the activation energy of the reaction.
Since a catalyst is not used up in the reaction, the following statement applies:
It undergoes no permanent change during a reaction
It does not participate in a chemical reaction

Answer:
Group B
Explanation:
<u>The fish in group B are those in the control group.</u>
<em>A control group during an experiment represents a group of the subject that is subjected to all experimental variables except the independent variable - the manipulate-able variable that is supplied by the experimenter which directly affects the dependent variable. </em>
In this case, the independent variable is the type of food given to the two groups of fishes - microwaved or regular food while the dependent variable is the time it takes for the fishes to swim through the maze. Since the focus of the experiment is to see if microwaved food enhances the swimming speed of fishes, the group of fish that receives microwaved food would represent the treatment group while those that received regular food would be the control group.
Hence, group B represents the control group.
