Answer:

e. binds to an inducer to activate it.

Explanation:

An active repressor binds to the operator (operon) to either block or start transcription. Some of these proteins are needed routinely, while others are needed only under certain circumstances. For instance, lactose in the lac operon will turn the gene off if the active repressor protein binds to it.

How did totalitarian regimes in the Soviet Union, Italy, Germany, and Japan come to
stira [4]

Explanation:

A totalitarian ruler leads a government that maintains complete control over every

part of public and private life of the citizens in that country. The economic problems

that resulted from World War I and the Depression led people to question

whether democratic government could improve their lives. Totalitarian

governments appeared to provide a sense of security and offered a

strong direction for the future.

Both Communism and Fascism used aspects of totalitarianism

as part of their governments. In general, both used dictators, only

allowed one political party, and denied many individual rights.

Police terror was used for control and to get rid of any opposition.

Controlling media sources (newspapers, television, radio etc.)

with propaganda and limiting what was reported helped influence

what people thought. However, Fascism believed in an extreme form

of nationalism and pride in the country, while Communism focused on

the spread of their beliefs worldwide. Communism did not allow private

property and eliminated social classes. Fascism believed that each class

had a role to play in society and supported private property. During the 1920s

and 1930s, four major totalitarian governments developed – one was Communist,

The Soviet Union under Joseph Stalin

After Vladimir Lenin’s death, Joseph Stalin took power. He wanted to strengthen his power and the Communist state. He used

his secret police to stop any riots and arrest or kill anyone who spoke out against him. In 1933, he began the Great Purge to

eliminate his political rivals in the Communist Party and the government. He knew that in order to

compete with other modern countries, the U.S.S.R. (Soviet Union) needed to fix its economy. He

began a series of Five Year Plans to improve the Soviet Union’s industries. Production of steel,

coal, and oil increased dramatically, but Stalin set impossibly high production rates. Stalin took

control of all privately owned farms and began a program of collectivization. Hundreds of families

worked the collective farms to produce food for the country. Many landowners and peasants

resisted by destroying fields and killing their cattle and sheep. Millions died as a result of famine

from the damages and also attacks by the secret police to stop the rebellions. By the mid-1930s

Stalin changed the Soviet Union into a totalitarian state and made it into an industrial power.

Italy under Benito Mussolini

In the early 1920s, Italy was struggling economically and politically. Benito Mussolini’s Fascist

Party fought with the Communists for political power and won. Mussolini promised to restore the

power and glory of the Roman Empire. One way to do this was to expand Italy’s empire. In 1935, Mussolini invaded Ethiopia in

East Africa. Italy continued to expand by invading Albania in 1939. These invasions elevated Mussolini’s popularity and control.

Japan under Emperor Hirohito and Hideki Tojo

When the Great Depression hit Japan, many Japanese blamed the government for the economic problems. Military leaders

gained public support and won control of the government. Because the military kept Emperor Hirohito as the symbolic leader,
