Answers

Answer 1

Answer:

1.  Patterns in the distribution of living and fossil species tell us how modern organisms evolved from their ancestors.

2.They help in that, many recently discovered fossils form series that trace the evolution of modern species from extinct ancestors.

3.Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

4.The shell of a clam and the shell of a lobster are probably analogous, because they have a common function

5.The use of molecular clocks to track evolution includes both ribosomal RNA sequences for deep relationships and mitochondrial DNA for recent divergences.

6.The Grants have documented that natural selection takes place in wild Galapagos finch populations frequently, and sometimes rapidly, and that variation within a species increases the likelihood of the species adapting to and surviving environmental change.

Explanation:

Answer 2

Distributional patterns of both extant and extinct species show us how contemporary animals diverged from their ancestors. It is the answer of Part 1.

What is the meaning of evolutionary change?

The term "evolutionary change" refers to the heritable changes that occur through time in populations and species as a result of processes including sexual selection, random genetic drift, and natural selection.

Answers of the other parts are as follows:

Part 2

They aid in the formation of series of fossils that chart the development of contemporary species from extinct ancestors.

Part 3

According to evolutionary theory, homologous features that have been modified to serve various purposes descended from a common ancestor.

Part 4

Considering that they serve the same purpose, the clam and lobster shells are likely comparable.

Part 5

Both ribosomal RNA sequences for distant relationships and mitochondrial DNA for more recent divergences are used as molecular clocks to study evolution.

Part 6

The Grants have established that variety within a species enhances the likelihood that the species will adapt to and survive environmental change. Natural selection occurs regularly, and sometimes fast, in wild Galapagos finch populations.

To what extent did the political cartoons of the gilded age expose the corruption of the era? Cite at least 4 cartoons in your response

Answers

Answer:

The Gilded Age (c.1870 to 1900) was sandwiched between the Civil War and the Progressive Era, two periods in which politics “really mattered.” In contrast, the intervening decades seem to offer only lessonsin disillusionment and cynicism. The end of Reconstruction left a sorry mess in the South; the Homestead Act and railroad grants culminated in a Western bust, followed by a massive depression in the 1890s that failed to evoke a New Deal. The Populist movement collapsed, and Republicans’ crowning achievements were a high tariff and maintenance of the gold standard. There are, however, other ways to teach Gilded-Age politics, perhaps even to recapture its excitement, while at the same time teaching social history. Political cartoons flourished in these years, partly because of new technologies of mass circulation but also because of the intensity—even viciousness—of partisan debate. Such cartoons reflected the society that produced them, with references ranging from the Bible to the nationwide bicycle craze. They vividly represent the prejudices of the white, Protestant, middle-class majority, and of regional and partisan factions within that majority. The following analyses of cartoons from an article entitled “The Corrupting of New York City” by Peter Baida and those found in The American Pageant, Chapters 23 & 24 reveal key issues at stake during this era. FYI Significant Political Cartoonists of the Gilded Age • Thomas Nast of Harpers Weekly** • Joseph Keppler of Puck* • Frank Beard of The Ram’s Horn* • Eugene Zimmerman of Judge* • Grant Hamilton, Bernhard Gilliam, James Wales, W.A.

Explanation:

Appeals for money almost always will reference one of your interests which the candidate supports. Are made by PACs, not campaigns. Are then used to fund various parts of the campaign. The correct option is D.

A)They feared a government with unlimited power.
B)They favored the poor over the wealthy and elite.
C)They wanted to increase powers of the states.
D)They hoped to expand the democratic process.

Answers

Answer:

A) They feared a government with unlimited power.

Explanation:

A constitution can be defined as a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens.

The Federalists refers to a group of people who were keenly interested in the ratification of the federal constitution of the United States of America in 1787. They unanimously believed and agreed that the Articles of Confederation wasn't adequate or sufficient enough to enhance good governance and serve the needs of the United States of America and as such required a new government having greater powers at the national level.

The framers of the U.S. Constitution included the concepts of federalism, checks, and balances, and separation of powers because they feared a government with unlimited power.
