Kennedy and the shadow on FDR essays

Kennedy and the shadow on FDR essays Since the beginning of the glorious post-World War II days to the dawn of the revolutionary 1960's, the United States had been led by an uninspiring, "ordinary" farmer who had led the country into yet another war. Additionally, despite the continuing economic boom, the obsequious societal tension produced by the enduring Cold War, the escalating civil rights movement, and the alienation of the "Other America" helped to cultivate a nation in great need of hope and inspiration as it entered the tumultuous era of the 1960's. It was such a scenario which John F. Kennedy faced upon his presidential inauguration; one which Kennedy's presence would, over the course of his three years in office, help to simplify. However, though his positive effects upon the country are undeniable, these effects resulted more from Kennedy's inspirational demeanor, rather than his lacking in both leadership skills and "presidential" character and as with every president since 1945 a shadow of FDR loomed over the office. There are those who believe that Kennedy shared many of the same characteristics Franklin D. Roosevelt displayed during his career. This is a fairly presumptuous thing to do, given the height to which history has rightly elevated Roosevelt - the conqueror of depression and war, who's mere image carried the ability to move citizens to tears in inspiration. However, Kennedy undeniably carried on some of Roosevelt's legacy as an inspiration; where Roosevelt inspired with blind optimism and courage, Kennedy inspired with seemingly youthful vigor. He was, after all, the youngest president to date, and his similarly youthful and intellectual cabinet, classic good looks, and beautiful family restored spirit in a dejected public, convinced that a young man of great ability and progressive ideals sat in the Oval Office set the country at ease. A testament to just how high in opinion the public held him was its enthusiastic approval when, after Kenne...

Homologous and Analogous Structures Whats the Difference

Homologous and Analogous Structures What's the Difference SAT / ACT Prep Online Guides and Tips Have you ever thought about how different kinds of animals have body parts that work in similar ways? Like bats and bees? Both creatures have wings - even though their bodies are structured very differently. The key to understanding these differences lies in knowing what homologous and analogous structures are. In this article, we'll talk about each type of structure and discuss the similarities and differences between them. What Are Homologous Structures? Homologous structures are similar structures in related organisms. The most important thing to remember about homologous structures is that they share common ancestry. In other words, only organisms that are somehow related to each other can have homologous structures. For example, a chimpanzee’s arm and a human’s arm are homologous structures. Both sets of arms have a similar structure and use and chimpanzees and humans share a common ancestor. What Are Analogous Structures? Analogous structures are similar structures in unrelated organisms. These structures are similar because they do the same job, not because they share common ancestry. For example, dolphins and sharks both have fins, even though they aren’t related. Both species developed fins because of how (and where) they live. What’s the Difference Between Homologous and Analogous Structures? Homologous and analogous structures have several key differences. Let’s take a look at them: Homologous Structures Analogous Structures Shared ancestry Similar internal structure May look different externally No shared ancestry Similar function May look similar externally Homologous Structures Example A great example of homologous structures are the wings of a bat and the arms of a human. Bats and humans are both mammals, so they share a common ancestry. Both a bat’s wing and a human’s arm share a similar internal bone structure, even though they look very different externally. The wing and the arm also perform different functions - wings help bats fly, while arms help humans interact with their world in a very different way. Analogous Structures Example A great example of analogous structures are a bat’s wing and a bee’s wing. Bats and bees do not share common ancestry, so the structures cannot be homologous. Both bat wings and bee wings serve a common purpose - helping bats and bees fly! The structures look similar on the outside, too. However, their internal structures are very different - bat wings have a bony structure with muscles, while bee wings are membranous extensions. Homologous and Analogous Structures - Key Takeaways Many animals have body parts that look similar, even though they don’t share common functionality. Other animals have body parts that look totally different, but have a shared background. Here’s the difference between homologous and analogous structures: Homologous structures are structures that may look or function differently from related organisms. Analogous structures are structures that look and function similarly from unrelated organisms. What’s Next? Currently taking Biology and need help with other bio topics?
