question:
One member of this phylum, Strongylocentrotus purpuratus, is often used to study developmental processes, and another, Pisaster ochraceus, is an example of a keystone species. Most members of this phylum have pedicellariae that possess three jaws, and some have a chewing apparatus known as Aristotle's lantern. Members of class Asteroidea of this phylum have an ambulacral groove, and the madreporite is the entrance to their water vascular system that includes tube feet. FTP name this phylum whose "spiny skinned" members have radial symmetry and include sand dollars, sea urchins, and sea stars.
answer:
Social Science


question:
These quantities are the arguments of the logarithms in the von Mangoldt function, which is itself summed to yield the second Chebyshev function. Using the evenly-spaced integer topology, Furstenberg re-proved that there were aleph-null many of these values. The work of Goldston et al. employing the Elliott-Halberstam conjecture was a precursor to Zhang's proof of bounded gaps between them. Thanks to the AKS algorithm, it is polytime-decidable whether or not a number is one of these numbers. The distribution of these numbers is described by the law "pi of x is asymptotic to x over log x," where "pi of x" is the function that counts these numbers. They are typically generated by sieving, as originally done by Eratosthenes. For 10 points, what numbers are divisible only by one and themselves
answer:
Science


question:
One of this author's works tells his child that is "cradled by my side" that he "shalt wander like a breeze" and that "all seasons shall be sweet to thee." Another of his works exclaims "Joy, Lady! is the spirit and the power" after he is unable to "see, not feel how beautiful they are." This author of "Frost at Midnight" and "Dejection: An Ode" wrote a more famous work which mentions (*) "Alph, the sacred river" flowing "Through caverns measureless to man." That work begins with an order for "A Stately Pleasure-Dome", while another work by this poet cries "Water, water, everywhere, Nor any drop to drink," after the speaker kills an albatross. For ten points, name this English poet of "Kubla Khan" and "The Rime of the Ancient Mariner."

Literature
