Space Science
This model places Earth at the center of the universe.
What is the geocentric model?
The variable you change on purpose in an experiment
What is the independent variable?
How many high tides and low tides occur daily?
2 high and 2 low (4)
All living things are made of these
What are cells?
The ability to pass on traits to offspring
What is heredity?
The invisible force that pulls objects toward each other, keeping us on the ground and making things fall.
What is gravity?
The variable you measure in an experiment
What is the dependent variable?
Name one piece of evidence of continental drift.
What are matching landforms, shape of the continents, fossils, etc?
This organelle directs cell activities and houses DNA
What is the nucleus?
A genotype with two identical alleles.
What is homozygous?
Is a property of matter that makes it resist changes in its motion because things tend to stay doing what they are already doing
Example: this keeps the Moon moving forward in space.
What is inertia?
The group that does NOT receive the experimental treatment.
What is the control group?
What happens to an object if forces are unbalanced?
What is that its motion changes?
This organelle controls what enters and leaves the cell.
What is the cell membrane?
Is this genotype heterozygous or homozygous
Rr
What is homozygous?
This forms when a massive star collapses inward.
What is a black hole?
Name all 5 steps of the scientific method in order

This boundary is where plates move away from eachother
What are divergent boundaries?
This organelle produces energy.
What is the mitochondria?
This refers to the physical traits an organism shows, such as hair color or the ability to roll your tongue.
What is phenotype?
Put in order from smallest to largest: star cluster, star system, universe, star, galaxy
What is star, star system, star cluster, galaxy, universe?
What is the difference between validity and reliability in an experiment?
What is validity means the experiment measures what it is supposed to measure, while reliability means the results are consistent when repeated?
What type of landforms are most commonly created at convergent plate boundaries?
What are mountains, volcanoes, or trenches?
Name all 3 parts of the cell theory
1. All living things are made of cells
2. Cells are the basic unit of life
3. All cells come from preexisting cells
A dominant allele is represented by R. If both parents are Rr, what percent of offspring show the dominant trait?
What is 75%?
