QUES: No single feature distinguishes Annelids from other invertebrate phyla, but they have a distinctive combination of features. Their bodies are long, with segments that are divided externally by shallow ring-like constrictions called annuli and internally by septa ("partitions") at the same points, although in some species the septa are incomplete and in a few cases missing. Most of the segments contain the same sets of organs, although sharing a common gut, circulatory system and nervous system makes them inter-dependent. Their bodies are covered by a cuticle (outer covering) that does not contain cells but is secreted by cells in the skin underneath, is made of tough but flexible collagen and does not molt – on the other hand arthropods' cuticles are made of the more rigid α-chitin, and molt until the arthropods reach their full size. Most annelids have closed circulatory systems, where the blood makes its entire circuit via blood vessels.
What is an annelid's cuticle made into?

ANS: unanswerable

QUES: Against the rested and re-armed Pusan Perimeter defenders and their reinforcements, the KPA were undermanned and poorly supplied; unlike the UN Command, they lacked naval and air support. To relieve the Pusan Perimeter, General MacArthur recommended an amphibious landing at Inchon (now known as Incheon), near Seoul and well over 100 miles (160 km) behind the KPA lines. On 6 July, he ordered Major General Hobart R. Gay, Commander, 1st Cavalry Division, to plan the division's amphibious landing at Incheon; on 12–14 July, the 1st Cavalry Division embarked from Yokohama, Japan to reinforce the 24th Infantry Division inside the Pusan Perimeter.
Who did General MacArthur ask to plan the amphibious attack?

ANS: Major General Hobart R. Gay

QUES: “The roots of all our modern academic fields can be found within the pages of literature.”  Literature in all its forms can be seen as written records, whether the literature itself be factual or fictional, it is still quite possible to decipher facts through things like characters’ actions and words or the authors’ style of writing and the intent behind the words. The plot is for more than just entertainment purposes; within it lies information about economics, psychology, science, religions, politics, cultures, and social depth. Studying and analyzing literature becomes very important in terms of learning about our history. Through the study of past literature we are able to learn about how society has evolved and about the societal norms during each of the different periods all throughout history. This can even help us to understand references made in more modern literature because authors often make references to Greek mythology and other old religious texts or historical moments. Not only is there literature written on each of the aforementioned topics themselves, and how they have evolved throughout history (like a book about the history of economics or a book about evolution and science, for example) but we can also learn about these things in fictional works. Authors often include historical moments in their works, like when Lord Byron talks about the Spanish and the French in ‘‘Childe Harold’s Pilgrimage: Canto I’’ and expresses his opinions through his character Childe Harold. Through literature we are able to continuously uncover new information about history. It is easy to see how all academic fields have roots in literature. Information became easier to pass down from generation to generation once we began to write it down. Eventually everything was written down, from things like home remedies and cures for illness, or how to build shelter to traditions and religious practices. From there people were able to study literature, improve on ideas, further our knowledge, and academic fields such as the medical field or trades could be started. In much the same way as the literature that we study today continue to be updated as we continue to evolve and learn more and more.
In what type of literature do authors make reference to Roman mythology and other old texts?

ANS: unanswerable

QUES: Standard 35mm photographic film used for cinema projection has a much higher image resolution than HDTV systems, and is exposed and projected at a rate of 24 frames per second (frame/s). To be shown on standard television, in PAL-system countries, cinema film is scanned at the TV rate of 25 frame/s, causing a speedup of 4.1 percent, which is generally considered acceptable. In NTSC-system countries, the TV scan rate of 30 frame/s would cause a perceptible speedup if the same were attempted, and the necessary correction is performed by a technique called 3:2 Pulldown: Over each successive pair of film frames, one is held for three video fields (1/20 of a second) and the next is held for two video fields (1/30 of a second), giving a total time for the two frames of 1/12 of a second and thus achieving the correct average film frame rate.
The technique in which with successive pair of film frames, one is held for three video fields, and the next is held for two, is called what?

ANS:
3:2 Pulldown
