What did Charles Darwin experiment with to test his idea of natural selection?

Answers

Answer 1

Answer:

Darwin saw natural selection as an overarching explanatory hypothesis that gave a causal explanation of evolutionary change, was consistent with the experience of plant and animal breeders, and made sense of a host of facts, such as he had uncovered in his research on barnacles, orchids, climbing plants, and many others. The evidence for natural selection, he asserts in a letter is “(i) On its being a vera causa, from the struggle for existence; and the certain geological fact that species do somehow change.

Native American organizations lobbied Congress in the seventies for reforms to federal Indian policy, achieving all of the following successes except:
-A Native American cultural center on Alcatraz
-Control of federal aid programs on tribal reservations
-Oversight of schools on tribal reservations

Answers

The Native American organizations achieved the success of control of federal aid programs on tribal reservations, but they did not achieve the success of a Native American cultural center on Alcatraz.

In the 1960s and 1970s, Native American organizations began lobbying Congress for reforms to federal Indian policy, which had historically been oppressive and detrimental to Native American communities. Through their activism and advocacy efforts, they were able to achieve several important successes, including gaining greater control over federal aid programs on tribal reservations and gaining oversight of schools on tribal reservations.

However, one success that they did not achieve was the establishment of a Native American cultural center on Alcatraz. In 1969, a group of Native American activists occupied the former federal prison on Alcatraz Island in San Francisco Bay and declared it a symbol of Native American sovereignty. The occupation lasted for over a year, and during that time, the activists lobbied for the establishment of a cultural center on the island that would showcase Native American art, history, and culture.

In Katz vs United states , the supreme court ruled on whether the police would tap a public phone without a warrant.

Answers

Answer:

Unconstitutional to tap a public phone without a warrant.

Explanation:

In Katz v. United States, 1967, the Supreme Court ruled that The Fourth Amendment protection should bring under its aegis the right to private conversation even electronically. In other words, the court ruled out that it was unconstitutional to wiretap electronic devices without a warrant.

Charles Katz was arrested for interstate gambling in 1965 with evidences from his telephonic conversation from a tapped telephone booth. However, his case became a much debated case on how far does the Fourth Amendment protection apply to.

Based on his case, the Supreme Court concluded that telephone booth becomes a private space when a person enters inside it, therefore it is unconstitutional to wiretap a telephone booth without a warrant.

Answers

Answer:

In my opinion it was Soviet Union, as they were trying to spread their ideology across the globe, sometimes even by interfering in the internal issues of certain countries.

Explanation:

Although, we can say that both countries contributed to the rise of tension, Soviet Union especially made things harder. They wanted to spread Communism, and didn't allowed civil liberties. On the other sides, they wanted to impose their strict regimes in the countries of Eastern Europe, and to destroy any type of rebellion against them.

By spreading their influence outside Eastern Europe they started endangering the states of capitalist democracy.

In one paragraph, argue whether U.S. citizens should be required to pass a civil service exam before working in the U.S. government. Support your argument with facts or examples.

Answers

Answer:

American citizens are humans which means that they have different skills and competencies. This means that even though they have the right as citizens to join the government as civil servants, it is imperative that they join the service in a manner that would be most beneficial to the country. This is why Civil Service exams are important. They gauge the skills of the applicants to determine if they would be good fits for the service they would like to join. For example, Shannon is no good at math and financials but applies to the Securities and Exchange Commission (SEC). If there were no civil service exams to test his competence, he might be hired and put in a position he would not be able to contribute to the government's efforts effectively.
