An object's change in position relative to a reference point.
What is Motion?
100
Contains genetic material(DNA) and chromosomes.
What is the Nucleus?
100
Process by which organisms change over time as those with traits best suited to an environment pass their traits to the next generation.
What is Natural selection?
200
The earth's outer layer is broken up into 7 lithospheric plates sometimes called the crust.
What is Plate tectonics?
200
How are stars formed?
Stars are formed from clouds of dust and gas

What's the difference between speed and velocity?
Speed is the distance traveled divided by time and velocity is the speed of an object in a particular direction.
200
Controls the release of energy from food;form ATP and called the POWERHOUSE of the cell.
What is the Mitochondria?
200
The theory based on scientific evidence,that describes how organisms change over many generation.
What is Evolution?
300
The plates move due to a circular motion of heat .
What is Convection current?
300
The nebula, protostar,star like the sun ,red giant,planetary nebula,white dwarf.
What is The life cycle of stars?
300
A)The rate at which velocity changes over time . It can change both speed and direction. B)What is the formula ?
A)What is acceleration? A=Vf-Vi/t or A=m/s2
300
Complex cells that have a nucleus;examples plants,animals,humans,protists,and fungi.
What is Eukaryotes?
300
1)Path of food energy from the sun to the producer to a series of consumers, in an ecosystem. 2) In an ecosystem, arrangement of several overlapping food chains.
1)What is a food chain? 2)What is a food wed?
400
When two plates move away from each other.
What is Divergent boundaries?
400
A)A collection of millions and billions of stars. B)Name the three galaxies and describe their shapes.
A) What is A galaxy? B)Spiral (spiral arms,bulge in the center ) Elliptical (no arms,oval-shaped,reddish color) Irregular (no definite shape)
400
A)An action exerted on a body in order to change the body's state of rest or motion. B) What is the formula? C) Explain balanced and unbalanced force.
A) What is Force? B) F=mxa C)Balanced force do not change and Unbalanced forces change
400
1)I have a cell wall and chloroplasts. 2)I have a long tail used for movement of thing throughout the cell. 3)It encloses the entire cell,and acts like a gatekeeper.
1)What is a plant cell? 2)What is a flagella? 3) What is the cell membrane?
400
This will show the relative amounts of energy at each trophic level.
What is the energy pyramid?
500
A) When two tectonic plates move towards each other resulting in a collision. B)When two plates move horizontally past each other.
A) What are Convergent boundaries? B)What are Transform fault boundaries?
500
A) Consists of all space,matter,and energy that exists now,in the past,or in the future. B)An observed change in the frequency of a wave when the source or observer is moving. C) The universe began 13-15 billion years ago with a gigantic explosion.
A)What is the universe? B)Doppler effect? C)The Big bang theory?
500
A)Explain Newton's first and second law. B) Explain Newton's third law. C) What is the formula for gravity on earth?
A) An object at rest remains at rest and an object in motion maintains it's velocity unless it experiences a net force. B)The unbalanced force acting on an object equals the object's mass times it's acceleration. F=mxa C) The attraction of earth for any object. g=9.8m/s2
