Answer:

2 levels of the independent variable and 0 levels of dependent variable

Explanation:

Levels of independent variable indicate the types of experiment here. Here we have the control experiment and experimental group.

The control group is the 50 children that took nutritious breakfast while the experimental group is the 50 children that took doughnuts /non nutritious food.

What is an important difference between Western Europe economies and Eastern European economies
Ostrovityanka [42]

Europe bases its economy on different economic activities. Though some of these activities are similar throughout the continent, Western Europe and Eastern Europe tend to have different focus areas. Western Europe bases much of its economic activities on service industries such as banking, trade, finance, and technology. Western Europe also manufactures products such as pharmaceuticals, automobiles, and aerospace crafts and technologies. Eastern Europe tends to focus on consumer goods and food processing. Agriculture and industry are more widespread in Eastern Europe than in Western Europe. Eastern Europe is working to shift its economy from a command economy to a mixed market, and it is beginning to add more and more service industries throughout the region.

Luda [366]
<span>The concept that ethnicities have the right to govern themselves is known as the r</span>ight of people to self-determination. This rule states that groups of people have right to choose their sovereignty, it means to decide that they want to form an independent state. The most important periods when this rule was applied were after the World War I, World War II and in the 1990s when many independent states emerged from former empires (the Great Britain or the Soviet Union) in Africa, Eastern Europe and Asia.
Nowadays this rule is on the one hand accepted but on the other still controversial when it comes to rights of ethnicities which strive for independence (ex. Scotland from the UK, Catalonia from Spain or Palestina from Israel).
