Biology
The organ that pumps blood to the rest of the body.
The heart.
Gravity, friction, electric, magnetic are all types of...
Forces.
A community of living organisms interacting with the non-living parts of their environment, such as air, water, and soil.
Ecosystem
The "stuff" which makes up all substances in the universe.
Matter.
Which of these elements is the most reactive?
Helium, Sodium, or Tin?
Sodium
The basic building block of life.
A cell.
The English scientists famous for his 3 laws of motion.
Isaac Newton.
The variety of life found in a place. This is measured commonly by species richness.
Biodiversity
The term for the temperature where a substance changes from a liquid to a gas.
Boiling Point
The unique role and position a species has in its environment
Ecological Niche
An organism that eats only plants.
Herbivore
If a car moves 200 meters in 5 seconds, what is its speed in meters per second?
40 m/s
Plantae, Animalia, Fungi, Protista, Eubacteria, Archaea
The 6 kingdoms of life.
The phase of matter with the highest kinetic energy. Also the most abundant phase of matter in the universe.
Plasma.
The 3 subatomic particles within an atom.
Proton, electron, and neutron.
The process where plants turn water, carbon dioxide, and sunlight into glucose.
Photosynthesis.
The number of cycles of a wave which pass a certain point in one second and is usually measured in Hz. For electromagnetic waves, the higher this value is, the higher energy the wave has.
Frequency.
The process by which species are formed, usually happens due to a group becoming reproductively isolated.
Speciation
The name of the phase change from gas to solid
Deposition
An essential macromolecule made of amino acid chains. It builds and repairs tissues, makes hormones and enzymes, and supports immune function.
Protein
This type of pathogen is a tiny infectious particle made of genetic information protected by a protein coat. It cannot reproduce on its own and is not usually considered a living organism.
A virus.
If a negatively charged particle has a weak positive charge in a fixed position to its left, and a strong negative charge in a fixed position to its right, which direction will it move?
To the left
The amount of total energy passed from one tropic level up to the next. For example, herbivores only absorb __% of the energy available to the trophic level below them (plants/primary producers).
10%
Which of these has the strongest attractive forces between its particles (think about their phase of matter at room temperature).
Oxygen, Gold, or Water?
Gold (solid)
Mysterious, invisible matter that makes up about 27% of the universe, but does not reflect, absorb, or emit light. It is about 5 times more abundant than normal matter.
Dark Matter
