Ecology
In a food web, these organisms eat primary consumers.
What are secondary consumers?
This is the main energy source that drives convection in Earth’s atmosphere.
What is the Sun?
The presence of this structure distinguishes eukaryotic cells from prokaryotic ones.
What is a nucleus?
A rift valley is formed at this type of plate boundary.
What is a divergent boundary?
This is the scientific term for a trait that increases an organism’s chance of survival.
What is an adaptation?
This type of ecological succession begins on bare rock and takes longer than its counterpart.
What is primary succession?
This type of system is associated with calm, sunny weather.
What is a high-pressure system?
This type of cell contains free-floating DNA and no nucleus.
What is a prokaryotic cell?
The Rocky and Scandinavian mountains being similar is evidence for this theory.
What is the theory of plate tectonics? (also acceptable: continental drift)
These adaptations involve inherited physical traits, like fur color or beak shape.
What are structural adaptations?
These observable differences, such as butterfly wing patterns, occur naturally within a species.
What are variations?
These two conditions are needed for a tropical cyclone to form.
What are warm ocean water and low pressure systems?
Eukaryotic cells are identified by having this structure.
What is membrane-bound nucleus?
This human activity increases fossil fuel emissions by moving people into cities.
What is urbanization?
This type of adaptation describes how an animal acts, like migrating or hibernating.
What are behavioral adaptations?
This term refers to inherited behavioral traits that help an organism survive.
What are behavioral adaptations?
Cold and warm surface currents can affect this atmospheric element, which determines weather.
What is temperature/air pressure?
This molecule, found in both prokaryotic and eukaryotic cells, carries genetic instructions.
What is DNA?
This boundary is where one plate slides beneath another, often forming volcanoes.
What is convergent (subduction)?
This adaptation helps a desert plant reduce water loss through narrow leaves or waxy surfaces.
What is a structural adaptation?
This type of factor includes living organisms in an environment, like coral and parrotfish.
What is a biotic factor?
A student observes sunny and cool conditions after rainfall. This type of air mass likely moved in.
What is a high pressure system?
This cell structure is semipermeable and controls what enters and exits the cell.
What is cell membrane?
Which of the following events would have the highest impact on Earth's climate?
1. Meteor impacts, volcanic activity, local wildfires
2. Meteor impacts, volcanic activity, and abrupt changes in ocean currents
3. Earthquakes, flooding, and plate tectonic activity
2. Meteor impacts, volcanic activity, and abrupt changes in ocean currents
Sweating and producing venom are examples of this type of adaptation.
What are physiological adadptations?
