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.
Answer:
The correct answer is (D)
Explanation:
Peter the Great was the Tsar of Russia between 1682 and 1725. He sought to transform Russia into a great European power, and sucessfully expanded the territory of the Russian Empire through a series of wars against its neighbors.
Worried for what he deemed to be the backwardness of his country, he also launched a modernization program, aiming to Europeanize Russia. He adopted European clothing styles, customs, and manners, and reformed the country's administrative systems such as the Duma and other consultative bodies following European models. He founded the city of St. Petersburg on the shores of the Baltic Sea, and modelled it after other Europeans capitals, with the city becoming Russia's window into Europe. As part of his modernizing drives, he <u>adopted </u><u>mercantilist</u><u> policies to stimulate growth of the economy</u>, in the same vein other Europeans power had done during that time. Peter the Great hoped to improve agriculture by adopting modern practices and to develop a domestic industry. However, due to Russia's economic backwardness and huge size, the mercantilist policies weren't as successful as expected and Russia remained a primarily feudal agricultural state.
While he felt short of his goal of fully Europeanizing Russia, Peter the Great's policies had a huge impact on Russia, transforming it into a major European power.
