What is a cell
100
having no net electrical charge
What is neutral
100
A great sea wave produced by a submarine earthquake, volcanic eruption, or large landslide. Commonly (but erroneously) called a "tidal wave"
What is a tsunami
100
Energy that is associated with the motion of an object.
What is kinetic energy
100
the blanket of air that surrounds the Earth. It is thickest near the ground and gradually fades away to nothing in outerspace.
What is the atmosphere
200
the branch of science concerned with the structure, function, growth, evolution, and distribution of living and non-living organisms
What is biology
200
the smallest particle of an element that retains the chemical properties of the element
What is an atom
200
Molten rock beneath the surface of the earth.
What is magma
200
The resistance to motion between two surfaces moving over each other. It is usually measured in terms of force and velocity.
What is friction
200
the ability to float, or in more technical terms - the upward forces exerted by a fluid on a body in it.
What is bouyancy
300
the cellular division that yields four gametes through two cellular divisions
What is meiosis
300
a tiny, incredibly dense positively charged mass at the heart of the atom
What is atomic nucleus
300
The direct change from the solid to the vapor phase (without passing through the liquid phase). Commonly occurs in ice and snow fields on sunny days above the snowline.
What is sublimation
300
The mechanical transfer of heated molecules of a gas or liquid from a source to another area, as when a room is warmed by the movement of air molecules heated by a radiator.
What is convection
300
a colorless, odorless, tasteless gas that is the most plentiful element in the Earth's crust. It was discovered in 1772 by Swedish chemist Carl Wilhelm Scheele.
What is oxygen
400
This term is an abbreviation for `deoxyribonucleic acid'.
What is DNA
400
An elementary particle found the atomic nucleus with a positive charge equal and opposite that of the electron
What is a proton
400
Very fine-grained sediments deposited by wind action. Commonly associated with the margins of continental ice sheets.
What is loess
400
The rate of change velocity with respect to time. It is calculated by subtracting the initial or starting velocity from the final velocity and dividing the difference by the time required to reach that velocity.
What is acceleration
400
incapable of mixing or attaining homogeneity.
What is immiscible
500
the part of a cell called that is the plastid containing chlorophyll and other pigments; in plants it carries out photosynthesis.
What is chloroplast
500
a very strong attraction between two or more atoms that are sharing their electrons
What is a covalent bond
500
Solidified lava that fills the conduit of a volcano
What is a plug
500
Relates temperature to wavelength, starting that hotter objects radiate most at shorter wavelengths.
What is Planck's Law
500
tiny droplets of one liquid floating in another liquid, such as oil droplets floating in water.
