Question: Protrusions of this substance in the spine are called Schmorl's nodes, and Tietze syndrome occurs when this is inflammed. Its fibro type can be found in symphyses, while the pinna is composed of its elastic type. The hyaline type of this substance is covered by the perichondrium. (*)  Intervertebral discs are made of this substance, which heals slowly due to its lack of blood vessels. Chondrocytes are cells found in this substance, and during endochondral ossification, it is replaced with bone. Patients with osteoarthritis have a loss of this substance, which normally helps lubricate joints. For ten points, name this connective tissue which makes up the human nose and ear.

Answer: Science


Question: The acceleration named for this person can take place when particles repeatedly cross the shock front   caused by a supernova. The type of gas named for this person exerts pressure even at absolute zero. This person and Paul Dirac worked out the statistical distribution of particles that obey the Pauli  Exclusion Principle, which is why such particles are named for this person. Those particles, which  have non-integer spins, are contrasted with particles named for Satyendra Nath Bose. Name this  Italian American who created Chicago Pile-1 in 1942, the first man-made nuclear chain reaction.

Answer: Science


Question: P-glycoprotein upregulates these complexes to facilitate the proliferation of dendritic cells, and one of their protein constituents has been found to associate with and regulate multiple growth- and transcription-related proteins, such as PTEN and c-Jun. One protein that makes up these complexes also catalyzes telomere addition to the ends of chromosomes and is called TEP1. They can be mobilized along microtubules to associate with the nuclear envelope, giving credence to the theory that they may be involved in intracellular transport processes. Ninety-six copies of their major protein constituent self-assemble into a barrel-like structure, although these organelles can also open into an octahedral flower-like configuration. These organelles' internal RNA molecules bind argonaute proteins and may mediate drug resistance in cancer cells. For 10 points, name these highly conserved cytoplasmic ribonucleoprotein organelles of 39-fold symmetry and uncertain function.
