Answer:
D texture of the jumping surface
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Furthermore, a controlled variable refers to anything or quantity such as group, person, event, etc., that is held constant by the researcher during an experiment and as such is limited.
In this scenario, you are designing an experiment to find out which type of frog can jump farther. Thus, the controlled variable (variable that does not change) in this experiment is the texture of the jumping surface because it is where all the frogs would be tested on i.e used for the jumping test.

<span>The Whiskey Rebellion was a tax protest in 1791 during the
presidency of George Washington. It is also known today as the Whiskey
Insurrections. This “whiskey tax” was actually the first tax that the
government of America imposed on a domestic product. It angered the farmers
because in these regions, whiskey was also used as a medium of exchange of
goods. It was formed by the federal government and eventually became a law in
1791. The goal was to generate revenue to help reduce national debt and was
applied to all distilled spirits. Whiskey back then was the most famous
distilled beverage in the US and the excise tax that was added to it was known
to have greatly contributed to funding the war debt during the American
Revolutionary War. </span>
Answer:
Control variable
Explanation:
During the conduction of experiments for research, a control variable is introduced as a variable the researcher conducting the experiment holds as a constant. It is neither the dependent variable nor the independent variable, but it is something that affects the outcome thereby making it important. Control variable and controlled variable are two different things as the latter is another name for independent variable.
