This atmospheric gas is the largest contributor to the natural greenhouse effect on Earth.
What is water vapour?
In cell membranes, this process moves particles from low concentration to high concentration using energy.
active transport
A reaction that reaches a state where the forward and reverse rates are equal.
Chemical equilibrium
This is Newton’s Second Law
force = mass times acceleration
factor completely:
x3−27
(x-3)(x2 + 3x + 9)
These vibrations are produced when rocks break along a fault and release energy.
What are earthquakes?
A change in DNA that can lead to adaptation or variation in a population.
Mutation (not evolution)
This principle predicts how a system at equilibrium will respond to changes in concentration, temperature, or pressure.
Le Châtelier’s Principle (NEEDS FRENCH ACCENT OR -400 POINTS)
The inward acceleration required to keep an object moving in a circular path.
Centripetal acceleration
Solve for x (0° ≤ x ≤ 360°):
2sinx−1=0
sin(x) = 1/2
x =30°, 150°
This rock type forms from layers of sediments that get compressed over long periods of time.
What is sedimentary rock?
This system of naming organisms uses a two-part Latin name (genus + species).
Binomial nomenclature
_CH3CH2CH2CH3 + _O2 → _CO2 + _H2O
2 CH3CH2CH2CH3 + 13 O2 → 8 CO2 + 10 H2O
The property of a system that remains constant when no external forces act during a collision.
Momentum
An investment of $5000 is compounded annually at 6%. What is the total value after 10 years?
$8954.25
This natural process traps heat in Earth’s atmosphere and keeps the planet warm enough to support life.
What is the greenhouse effect?
The process in which new species form through long-term evolutionary divergence.
Speciation
Why does oil have a higher boiling point than water, despite not having dipole-dipole forces and hydrogen bonds?
The boiling point of oil is significantly greater than that of water because the sheer size of a molecule of oil creates strong van der Waals forces. This is stronger than the IMF from hydrogen bonds and dipole-dipole, which are exhibited in water.
this is the ratio between the periods of a pedulum on earth and a planet that has 6x the strength of the gravational pull of earth

This eon represents nearly 88% of Earth’s history and includes the formation of Earth, the first oceans, and the earliest life.
