The type/family of viruses that is causing the worldwide pandemic currently. 

coronavirus

The color of visible light that has the highest frequency, and therefore, the highest energy.

Violet/Indigo (Accept blue)

100

The type of force that prevents an object on a table from falling under the influence of gravity. 

Normal force

The type of conditioning where a punishment or reward is given in order to reinforce or discourage a particular action. Example: parent hitting a child for bad grades. 

Operant Conditioning

100

This effect is the primary cause for the global warming of the earth, occurs when certain gases in the atmosphere traps heat, preventing it from escaping. 

Greenhouse effect

200

The type of RNA that makes up ribosomes

rRNA

200

The proposed substance (we have no idea what it actually is) that is causing the accelerated expansion of the universe. 

Dark energy

200

The type of friction that is acting on an object when the object is not moving.

static friction

200

The time of year when the hours of day and the hours of night are approximately equal. There exists spring and autumn variants of this. 

equinox

200

The change in momentum is also called the? 

Impulse

300

The process by which the information in the mRNA, with the help of ribosomes, is turned into a sequence of amino acids, which folds to make a functional protein. 

translation

300

The explosion of smaller stars that results in a white dwarf. 

Planetary nebula

300
The weight of an object that masses 90 kg? Round your answer to the nearest whole number. (g = 9.81)

300

What type of tide is formed when the difference between high tide and low tide is the lowest, caused by  the perpendicular alignment of the sun and the moon relative to the earth?

neap tide

300

The aquatic biome where a freshwater source, usually a river or a lake, meets the ocean. 

Estuary

400

This type of innate behavior occurs when an animal sees a sign stimulus, then initiates a particular action in response to that sign stimulus. Examples: geese automatically pushing any object near their nest into the nest, baby birds opening their mouths when their parents come to feed them.

Fixed Action Pattern

400

The two values that are plotted on a hertzsprung russell diagram

Luminosity and Temperature

400

The coefficient of static friction and kinetic friction of a surface are 0.2 and 0.1, respectively. Cindy tries to push a couch that weighs 100N, and it starts moving. What is the force of static friction on the couch? 

10

400

The spectral class of our sun?

G

400

The type of mimicry where a harmless, palatable species mimics a harmful, unpalatable species.

Batesian mimicry

500
In a virus, it is through this process that it can change into a different type/strain of virus. Happens randomly. Cancer cells may also be formed through this process, if you are unlucky enough to have this occur on a gene that controls cell division. 

Mutation

500

What are the name of neutrons stars that emit radio waves in addition to spinning extremely rapidly?

pulsars

500

A 2 kg ball is moving to the right at 40 m/s. It bounces off a wall, and is now moving to the left at 40 m/s. What is the impulse experienced by the ball, in kg m/s? 

160

500

The process by which toxins are accumulated in higher amounts in animals that are higher up in the food chain. 

Biological magnification

Einstein's second theory of relativity, which states that nothing can be faster than the speed of light, and explains why nothing can escape from the gravity of a black hole. 

Einstein's special theory of relativity
