Evolution
This is the process where organisms with helpful traits are more likely to survive and reproduce.
What is natural selection?
This is the name of the ancient supercontinent.
What is Pangaea?
This is the basic unit of life.
What is a cell?
This is the movement of particles from high concentration to low concentration.
What is diffusion?
A living thing made of only one cell is called this.
What is a unicellular organism?
This word means a new species forms over time.
What is speciation?
This happens when long-term weather patterns on Earth change.
What is climate change?
This part of the cell controls the cell’s activities.
What is the nucleus?
This is the movement of water across a membrane.
What is osmosis?
A group of similar cells working together is called this.
What is a tissue?
Charles Darwin studied these birds to help explain evolution.
What are finches?
This was a time when much of Earth was much colder and covered in ice.
What is an Ice Age?
This jelly-like material fills the inside of the cell.
What is cytoplasm?
In diffusion, particles move until they are more evenly this.
What is spread out?
A heart is an example of this level of organization.
What is an organ?
Darwin noticed these on finches were different depending on the food available.
What are beaks?
When continents move apart or climates change, populations may become separated and eventually form a new ______.
What is a species?
This structure controls what enters and leaves the cell.
What is the cell membrane?
Which temperature made the food coloring spread faster in the diffusion experiment?
What is hot/warm water?
Put these in order from simplest to most complex: organ, organism, tissue, cell, organ system.
What is cell → tissue → organ → organ system → organism?
Helpful inherited features that improve survival are called these.
What are adaptations?
Earth changes can force organisms to migrate, adapt, or do this if they cannot survive.
What is go extinct?
This type of cell has no nucleus.
What is a prokaryotic cell?
Which temperature made the food coloring spread slower in the diffusion experiment?
What is cold water?
Plants and animals are made of many cells, so they are this.
What are multicellular organisms?
