Matter cannot be created or destroyed during a chemical reaction.
What is the Law of Conservation of Mass?
An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.
What is Newton’s First Law of Motion?
A graph that classifies stars based on temperature and luminosity.
What is the Hertzsprung–Russell (H-R) diagram?
What is a producer?
A characteristic that helps an organism survive in its environment.
What is an adaptation?
When balancing a chemical equation, this must be equal on both sides.
What is the number of atoms of each element?
This quantity increases when net force increases and mass stays the same.
What is acceleration?
Hot, bright stars are located in this region of the H-R diagram.
What is the upper left?
This shows the transfer of energy from one organism to another in a single pathway.
What is a food chain?
The thick fur of a polar bear is an example of this type of adaptation.
What is a structural adaptation?
A solid that forms when two clear liquids are mixed.
What is a precipitate?
The formula used to calculate acceleration when net force and mass are known.
What is a=F/m?
(or What is Newton’s Second Law?)
The day-to-day condition of the atmosphere.
What is weather?
Living and nonliving components of an ecosystem interact in this system.
What is an ecosystem?
A bird’s hollow bones help it fly because structure supports this.
What is function?
If mass appears to decrease during a reaction, it is most likely because the system was not this.
What is closed?
When a skater pushes against a wall and rolls backward, the wall pushing back on the skater is explained by this law.
What is Newton’s Third Law of Motion?
When a cold air mass pushes under a warm air mass, this type of front forms.
What is a cold front?
When a population grows too large for available resources, this limiting factor increases.
What is competition?
When organisms with helpful traits survive and reproduce more successfully than others, this process occurs.
What is natural selection?
In a balanced chemical equation, atoms are not created or destroyed but are this.
What are rearranged?
If two forces of 10 N act in opposite directions on an object, the net force is this.
What is 0 newtons?
A star with high temperature but low luminosity would be classified as this.
What is a white dwarf?
Energy decreases at each trophic level because most of it is lost as this.
What is heat?
An internal structure in plants that transports water from roots to leaves.
What is xylem?
