100

What is weight?
The product of gravitational acceleration and mass.

100

What is upwards?
When displacement is upward, it is the direction of the force used to calculate work.

100

What is zero?
The number of offspring with aa genotype from parents who are both AA.

100

What is a clone?
It is the name given to an identical genetic copy of an organism.

100

What is eutrophication?
The type of water pollution occurring from disregard of either the P or N cycle.

200

What is 9.8 N/kg or 9.8 m/s^2?
The acceleration on a 98 N weight with a mass of 10 kg.

200

What is 5 J?
The amount of work used to displace a 10 N weight over a distance of 500 cm?

200

What is DNA?
It is the largest molecule in the nucleus.

200

What is an "eye"?
It is the part of the potato, which if cut and planted, can turn into a clone.

200

What is shallowness?
It is the effect on lake-depth from eutrophication and also a personality characteristic of people who value objects over humans.

300

What is horizontal?
The direction of the effective force for a car rolling on the street.

300

What is 1000 J?
The amount of work needed to give an object an extra 1000 J of potential energy, assuming no change in kinetic energy.

300

What is uracil (U)?
The molecule in mRNA that pairs with DNA's adenine?

300

What is electricity?
It is the form of energy needed to get a cloned egg to divide.

300

What is hydrogen phosphate (HPO4 2-) ?
Aside from phosphate, it is the other ion created by bacterial decomposition.

400

What is 49N?
If the sine of 30 degrees is 0.5, it is the effective force for a 10 kg mass sliding down a hill with that slope.

400

What is 10 m/s?
If a 10 kg object had 500 J of total energy, and it was dropped, how fast was it moving when it hit the ground?

400

What is 16?
The number of squares needed to figure out the possibilities for AaBb X AAbb.

400

What is 1?
Theoretically the number of cells needed from a donor to supply the DNA to the nucleus-free egg.

400

What is bioaccumulation?
The process that causes toxins to pile up in the food chain when the ingestion rate exceeds the excretion rate.

500

What is 1/6?
The ratio of gravitational accelerations for moon/earth if a 60000 N spaceship weighs 10000N on the moon.

500

What is 9 times?
It is the increase in impact-force for a car going three times faster than normal.

500

What is an amino acid?
It is the smallest of the key molecules involved in translation.

500

What are stem cells?
These undifferentiated cells are found in young tissues and also shortly after fertilization for both cloned and normal organisms.

500

What is 5000 kg?
The mass of a killer whale whose tissues had a concentration of 2 ppm of PCBs if a total of 10 g of PCBs were inside the whale.
