This is the transmission of thermal energy through space and/or substances.

What is heat transfer?

100

This number of chromosomes in each human reproductive cell.

What is 23?

100

The force that keeps earth orbiting the sun, and the moon orbiting the earth, and battles inertia.

Gravity.

100

Why warm air rises.

Air particles heat and become less densely packed (less dense).

200

This particle is made of two different types of atoms (two different elements).

What is a compound?, or what is a compound molecule?

200

This is thermal energy transmitted from a warm object to a cold object through touch, while this is thermal this other is thermal energy transmitted through open space.

What is conduction and radiation?

200

Heredity is the subject related to the passing on of these visible characteristics, known as...

What is traits?

200

Made of nickle-iron, this part of the earth shares its name with part of an apple, but is split into two these two sections.

What is the inner and outer core.

200

Southeastern Massachusetts has cooler springs and warmer falls than central and western Massachusetts because of heat transfer from THIS.

The ocean (specifically, the gulf stream)

300

The law of conservation of matter states that all of the atoms in the reactants must...

What is "appear in the products"?

300

Convection of warm moist air takes place off of a heated land mass, resulting in this visible phenomenon at 15,000+ feet elevation.

What is cloud formation, or ice particle formation in clouds.

300

Each one of almost all human cells have THIS many pairs of chromosomes, carrying the instructions for all of the whole organism.

What is 23 pairs, so 46 total.

300

THIS motion gives us day and night, while THIS motion gives us seasons.

What are spin (or rotation) and orbit (or revolution).

300

THIS newton's law of motion explains half of earth's path around the sun, stopping a fast-moving object, and the difficulty of getting a large object to move.

Which is Newton's first law, or law of inertia.

400

The numbers needed to balance the equation 

H2O + electricty --> H2 + O2 

What are "2" before the H2O and "2" before H?

400

This is the result of the intense interaction of a warm, moist air mass and a cold, dry air mass.

What is storm front and/or precipitation?

400

THIS is where chemical instructions are stored in THIS, the smallest representative form of life.

The nucleus of the cell?

400

Plate tectonics is the process of pancake-like plates of earth's crust moving around on earths asthenosphere  - a phenomenon that is caused by convection in THIS one of earth's layers.

What is the mantle.

400

THIS cellular powerhouse is why you inhale (blank) and exhale (blank).

What are mitochondria, O2, and CO2.

500

The atoms of this element, found in baking soda and citric acid, can bond with all other elements because it has 4 electrons in its outer shell, and ___ protons in the nucleus.

What is carbon, and six protons?
500

This is the result of the rising and falling of nucleated water droplets in a cumulonimbus cloud.

What is hailstones, or hail?

500

The ratio of genotypes due to the cross of two heterozygote parents.

What is 1:2:1?

500

THIS force is weaker when the sun is perpendicular to the earth in the moon-earth-sun system, compared to when they are all in line (and works the same in other planetary systems).

What is tidal force?
500

Natural selection is when a group of similar organisms are killed off by predators, disease, the environment, etc., and results in differences in the organism(s) left. When we do this to benefit ourselves by creating new organisms, it's called THIS, and now we can even just change the (blank)

What is artificial selection (or selective breeding), and DNA.
