| Question | Answer |
|---|---|
| This molecule reacts with water to form the acid that causes ocean acidification. Water and this molecule are the products of combustion reactions, which is why burning (*) natural gas and coal cause it to enter the atmosphere. | Carbon Dioxide |
| Rotating examples of these objects are called pulsars. These objects form after the supernova of massive stars. For ten points, name these small yet incredibly dense stars which are made up of namesake uncharged particles. | neutron stars |
| Arrhenius equation. This quantity expresses the average kinetic energy of particles in a substance. In ideal gases, the number of moles times the constant R times (*) this quantity equals pressure times volume. | temperature |
| The (#) sum of reciprocals of squares of the natural numbers is equal to this number squared over 6. Since this number is the inverse cosine of -1, it is the number of radians in 180 degrees. | pi |
| This scientist’s death from aplastic anemia was caused by repeated exposure to substances like the ore pitchblende. One of two elements discovered by this scientist, (*) polonium is named after where she is from | Marie Curie |
| The Casparian strip (#) acts as a screen within the cortex of this structure, and the strangler fig kills trees by growing the adventitious type. Mycorrhizae [my-kuh-RYE-zee] are symbiotic relationships between fungi and these plant organs | roots |
| In this (#) organ, proper contraction of papillary muscles prevents click-murmur syndrome. This organ, whose Purkinje [per-KIN-jee] fibers may be damaged by infarction, contains the Bundle of His. It can be examined through (*) EKG | heart |
| One (#) example of these species, cobalt-60, is the major radiation source for cancer therapy. The extra mass in heavy water comes from deuterium, a hydrogen example of these atoms. Another example of these elements is denoted 14 | isotopes |
| A complex (#) in this organelle's process is called succinate dehydrogenase. Ubiquinone is found in this organelle. A protein found here rotates as hydrogen ions move down their concentration gradient. | mitochondria |
| During (#) an experiment named for this material, Hans Geiger counted flashes of light on a zinc sulfide screen, generated after an alpha particle was shot at a foil of this metal | gold |
| An (#) early version of this concept was proposed by Aristarchus of Samos. This concept replaced an idea based on “deferents” and “epicycles” that was promoted by Ptolemy. | heliocentrism (aka the sun is the center of the universe) |
| This function (#) of 2x can be written as two times this function of x times its cofunction of x. This function, the reciprocal function of cosecant, is positive for angles in the (*) first and second quadrants. and is the first step of SOH CAH TOA | Sine |
| Successive (#) versions of this type of function are known as jerk, snap, crackle, and pop.The power rule and (*) chain rule are commonly used to find this type of function. | derivative |
| A 2015 (#) study of this region by coda-wave cross-correlation found that it contains spheres with iron crystals aligned at right angles to each other. This region lies under the “D double-prime” layer, and although (*) P-waves are transmitted through it, | core (if you get to P waves slap yourself) |
| Einstein and Debye [Duh-BYE] name different models for the lattice structure of matter in this phase. Even at absolute zero, helium will never reach this phase at standard pressure | solid |
| No Niche The allopatric model led to different rodent forms of these entities on each side of the Grand Canyon, while different (*) beak shapes mark finch examples of these in the Galapagos | species (if you get to the end slap yourself) |
| Alpha helices and beta sheets in proteins are stabilized by these interactions. Two of them are found in a base pair between adenine and thymine on opposite strands of the (*) double helix of DNA. | hydrogen bonds |
| The Kirkwood gaps where traveled by to Vesta in 2011. The largest body in this area was classified as a dwarf planet in 2006; that body, (*) Ceres, is roughly 3 astronomical units from the Sun and is the nearest dwarf planet to Earth. | asteroid belt |
| During (#) earthquakes, this substance can undergo liquefaction. Texture triangles are used to classify this substance, whose first three layers are the O, A, and B horizons. | soil/dirt |
| Christmas (#) disease is a form of this illness marked by frequent epistaxis, Teenager Ryan White contracted HIV in 1984 while being treated for this condition with a (*) transfusion and male decadence of queen Victoria had this. | hemophilia |
| Expressions such as “Sine squared plus Cosine squared equals one” are called his namesake identities. Three positive integers that fit this man’s namesake theorem are called his (*) “triples.” | Pythagoras |
| James Forbes. These objects grow at accumulation zones and shrink at ablation zones. These objects can form amphitheater-like hollows called cirques, and (*) debris accumulated by these objects can form drumlins | glaciers |
| One deposit of one rock of this type is a bed of Cambrian Explosion fossils found near Mt. Burgess; that rock is well known for a kerogen-rich "oil" variety. In addition to (*) shale | sedimentary |
| For 10 points, name these solutions made of a weak acid and its conjugate base, exemplified by bicarbonate in the blood, which resist changes in pH. | buffer |
| The (#) theoretical precursor to the Bose-Einstein Condensate, the Bose Gas, was a gas made of these particles. | photons |
| This (#) number is the only number that is used in the expression of the golden ratio through continued fractions. Raising i to the fourth power gives this number, while raising anything to the zeroth | 1 |
| The Debye [deh-BYE] length characterizes the strength of the electrostatic charge of particles in this state of matter. A tokamak’s (*) magnetic field can confine matter in this state, which may be partially or fully ionized, as seen in neon lighting and | plasma |
| Tuna achieve sudden bursts of speed because their muscular system has this property. A high percentage of brown fat helps infants maintain this property, which is upset during a (*) fever. | warm bloodedness (accept descriptions) |
| Bundle sends signals to Purkinje fibers via gap junctions between cells. Papillary muscles pull chordae tendineae during systole to open tricuspid and mitral valves in this | heart |
| build up of this causes Tay-Sachs disease, and vitamins A and D dissolve in them. Humans use adipose cells to store the triglyceride form of these, while their water-repellant quality makes them excellent insulation in marine mammals. | fat |
| The scale for measuring this quantity is named for a scientist who advocated megadoses of vitamin C, and that scale ranges from (*) 0.7 to 3.98. Fluorine has the highest value for this quantity on the Pauling scale. How much something pull in electrons | electronegativity |
| Repeated applications of this operation can be denoted using a capital (*) sigma. Performing this operation on two adjacent numbers in Pascal's triangle gives the number below them | addition |
