What is the most common substance in hemoglobin?
Oxygen or O2

What is the speed at which gravity waves propogade?
The Speed of Light or 300000km/sec

What is the biggest moon in the solar system?
Ganymede

What is the only liquid compositional layer of the earth?
The Outer Core

What type of hydrogen ions are formed when bases are combined with water?
Bases release negatively charged hydrogen ions that form hydroxide ions when combined with water.
200
What is the function of the rough OR smooth ER?
Rough Endoplasmic Reticulum: It contains ribosomes that manufacture proteins. Smooth Endoplasmic Reticulum: It contains large molecules like steroids and ions.
200
What is Heisenberg's uncertainty principle?
It's a principle in quantum physics that states that the position and momentum of any particle can never be correctly measured.

What is the only moon that is believed to have water beneath its surface because of it's geysers?
Enceladus
200
What is the weak uppermost layer of lava that solidifies first called?
Aa Layer
200
What is the acid that dissolves minerals and forms the stalactites and stalagmites?
Carbonic Acid
300
What are the molars called in carnivorous animals like lion and tiger? (They are used to break bones of their prey)
Carnassial teeth

Define terminal velocity AND tell what is the terminal velocity of a human?
Terminal velocity is the highest speed an object can reach while falling (or accelerating) towards another object. After reaching terminal velocity, the object stops accelerating. The terminal velocity of a human is 195 km/h. (Fun side note: The Empire State building was the first building that were you to jump off it, you would reach terminal velocity before hitting the ground.)

Name the planets that would be the morning or evening stars in the sky IF we lived on Jupiter.
Mercury, Venus, Earth and Mars

What is the second largest tectonic plate in the world?
North American Plate

Define what is diffusion.
Diffusion is the natural tendency of matter and energy to move down concentration gradients and spread evenly throughout a body.
400
What is the only organelle in your body which scientists think is alien? Also, say its function.
Mitochondria; Converts glucose to ATP (Fun side note: 1 glucose molecule=32 ATP units. Also you would die without Mitochondria.)
400
What are Quarks made of?
Trick question, we haven't recognized them yet if they even exist.
400
Why is Mercury cooler than Venus even though it is closer to the Sun?
Because Mercury has no atmosphere so it doesn't trap heat like Venus.'
400
Granite is a what type of rock?
Igneous Rock
400
Define an ionic bond and also give an example.
An ionic bond is a bond in which atoms bond together because of their different charges. Ex: When chlorine is brought close to sodium, chlorine steals an electron from sodium giving sodium a positive charge and chlorine a negative charge. So the bond together because opposite charges attract.
500
Define phagocytosis.
It is the process by which a protozoan gains energy.
500
Define AND/OR quantify one of the following: Planck Length, Planck Instant, Planck Temperature,
Plank Length: The smallest unit of measurement of length in the universe; 1.616199(97)×10^(-35) meters Planck Instant: The time it would require the fastest thing in the universe-light-to cross the shortest length in the universe:Plank Length; 5.39116(13)x10^(-44) seconds. Planck Temperature: The hottest temperature possible in the universe; 1.416833(85)x10^(32) Kelvins

What is the biggest moon in the solar system relative to the size of the home planet.
The Moon of Earth.

What is the 3rd tallest mountain in the world? Also tell the location.
Mount Kangchenjunga; Nepal/India

What will happen if you mixed a chemical with a pH of 4 with a chemical with a pH of 9?
It would create water along with a basic or alkaline salt.
