This structure contains DNA and is found inside the nucleus of a cell.
What are chromosomes?
100
This is the process by which organisms with traits better suited to their environment are more likely to survive and reproduce.
What is natural selection?
100
This part of the wave is how far it dips down and rises up (the height of the wave) from its resting position.
What is the amplitude?
100
These are cracks in the Earth's surface where two plates meet and earthquakes often occur.
What are faults?
100
This natural hazard happens when the Earth's surface shakes due to movement of tectonic plates.
What is an earthquake?
200
This process results in two genetically identical cells and plays a key role in asexual reproduction.
What is mitosis?
200
A rabbit born with slightly thicker fur survives a harsh winter better than others and passes this trait to its offspring. This is an example of what kind of advantage?
What is an adaptation?
200
This term describes how often a wave passes a point in a given amount of time.
What is frequency?
200
This type of rock forms from layers of sediment being pressed and cemented over time and often contains fossils.
What is sedimentary rock?
200
Scientists can use satellites and weather radars to predict this kind of severe storm that forms over warm ocean waters.
What is a hurricane?
300
I have the longest process of cell divison.
What is meiosis?
300
These structures, like the human arm and a bat wing, have different functions but similar bone structures, suggesting a common ancestor.
What are homologous structures?
300
Solar panels use this type of light wave to generate electricity.
What is an electromagnetic wave?
300
This process slowly breaks down rocks into smaller pieces without changing their composition.
What is weathering?
300
This is the top layer of earth that forms crust.
What is the lithosphere?
400
A __________ occurs in a gene that codes for fur color in rabbits. Some rabbits now have white fur instead of brown. Depending on the environment, this _________ could be harmful, helpful, or neutral.
What is a mutation?
400
When a species no longer exists and has no living members, it is considered this.
What is extinction?
400
A pencil appears bent when placed in a glass of water due to this wave behavior.
What is refraction?
400
These large-scale events can create islands and change weather patterns due to ash and gas release.
What are volcanic eruptions?
400
These resources like coal, oil, and natural gas cannot be replaced quickly once used.
What are nonrenewable resources?
500
This phase the organelle called a centriole in which fibrous tubes retract back inside it (in asexual reproduction).
What is telophase?
500
Variations in a population usually come from changes in this molecule that carries genetic information.
What is DNA?
500
True or False? In increasing wavelength the correct order is: radio waves, microwaves, infrared waves, visible light, UV rays, x-rays, gamma rays.
What is false?
500
The shifting of tectonic plates over millions of years has caused continents to drift apart in a process known as what?
What is continental drift?
500
As the human population increases, demand for this type of resource—like fresh water and land—also increases, leading to scarcity.
What are natural resources?
600
This is a type of asexual reproduction that occurs in bacteria causing them to split from a single cell to form 2 new identical cells.
What is binary fission?
600
This type of evolution occurs when unrelated organisms independently evolve similar traits due to similar environmental pressures.
What is convergent evolution?
600
In longitudinal waves this would be one of these two type of movements inward and outward.
What is rarefaction and compression?
600
This major geological event forms when one tectonic plate is forced under another, resulting in deep ocean trenches and mountain building.
What is subduction?
600
This type of resource, like wind or solar energy, can naturally replenish and helps reduce strain on Earth’s supply.
What are renewable resources?
