Joseph Fourier
What name, the Latin word for amber, is given to a naturally occurring alloy of gold and silver?
Electrum
What loop is the long U-shaped portion of the tubule that conducts urine within each nephron of the kidney, recovering water and sodium chloride from urine?
Henle
Which endangered creature, often found in marshlands, is also known as a “peewit” for its high, sharp cry?
(Northern) Lapwing
Campbell and Omura won the 2015 Nobel Prize in Physiology or Medicine for the discovery of which anti-parasitic drug? It traditionally treats heartworm as well as headlice.
Ivermectin
Hashimoto’s disease affects which organ of the human body? Another similar disease is toxic diffuse goiter, better known as Graves’ disease.
Thyroid
What is the name of the highest bone in the spine and neck found directly beneath the skull?
Atlas
Barnard 33, a nebula in Orion, is better known by which name, owing to its resemblance to a certain animal?
Horsehead
In which constellation was the first object widely accepted to be a black hole discovered? Its brightest star is Deneb.
Cygnus
Which Indian mathematician, despite little formal training, made substantial contributions to number theory and studied tau and mock theta functions?
Srinivasa Ramanujan
This sixth largest moon of Saturn is covered in ice, and it may have liquid water below its surface. That ice gives this moon a very high albedo, making it the most reflective body in the Solar System.
Enceladus
Which spacecraft, accompanied by the Huygens probe, orbited Saturn from 2004 - 2017 when it intentionally crashed into the planet to prevent contamination of any moons?
Cassini
This is the process of plants using up the sugars made through photosynthesis and turning them into energy for growth, reproduction, and other life processes.
Plant Respiration
a state of balance or a stable situation where opposing forces cancel each other out and where no changes are occurring
Equilibrium
Which element has the highest melting point?
Tungsten
This mixture is a type of colloid formed by combining two liquids that normally don’t mix
Emulsion
This is a dental filling material used to fill cavities caused by tooth decay. It is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper.
Dental Amalgam
This branch of biology studies the microscopic anatomy of biological tissues.
Histology
This solution contains more than the maximum amount of solute that is capable of being dissolved at a given temperature
Supersaturated Solution
Positive and negative values of charge were initially assigned by this American statesman and inventor who started studying electricity in 1742.
Benjamin Franklin,
This Scottish chemist first identified carbon dioxide in the 1750’s.
Joseph Black
A relationship between species where one benefits bu the other is unaffected is knows as?
Commensalism
What is the branch of science concerned with the chemical and physiological processes that occur within living organisms.?
Biochemistry
A magnet that has a north and south pole on opposite sides of it is called a?
Dipole Magnet
Which law of thermodynamics states that If two thermodynamic systems are in thermal equilibrium with a third system separately, then they are in thermal equilibrium with each other.
Zeroth
the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work
Entropy
These are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
Endothermic Reaction
During this reaction, energy is constantly given off, often in the form of heat.
exothermic reaction
What material is the best heat conductor?
Diamond
