100

The factor that is purposely changed in an experiment.

➡️ What is the independent variable?

100

This is the smallest level of biological organization that is considered alive.

➡️ What is a cell?

100

This organelle controls cell activities and contains DNA.

➡️ What is the nucleus?

100

This term describes day-to-day atmospheric conditions

➡️ What is weather?

100

This term describes the variety of living organisms in an area.

➡️ What is biodiversity?

200

The factor that is measured or observed in response to changes.

➡️ What is the dependent variable?

200

A group of similar cells working together to perform a function.

➡️ What is a tissue?

200

These organelles produce energy for the cell through cellular respiration.

➡️ What are mitochondria?

200

This term refers to long-term patterns of temperature and precipitation in an area.

➡️ What is climate?

200

These are species that are introduced to an ecosystem and cause harm to native species

➡️ What are invasive species?

300

Factors that remain the same throughout an experiment to ensure fairness.

➡️ What are constants (controlled variables)?

300

Multiple tissues working together form this level of organization.

➡️ What is an organ?

300

This organelle (found only in plant cells) creates food for the plant using energy from the sun.

➡️ What is the chloroplast?

300

Large geographic areas with specific climates, plants, and animals are called this.

➡️ What are biomes?

300

A species that has a disproportionately large impact on its ecosystem compared to its population size.

➡️ What is a keystone species?

400

This part of a graph shows the dependent variable and is usually located on the vertical axis

➡️ What is the y-axis?

400

This level includes organs working together to perform major body functions, such as the digestive or circulatory system.

➡️ What is an organ system?

400

This structure found in plant cells provides support and protection and is made mostly of cellulose.

➡️ What is the cell wall?

400

This biome is characterized by low rainfall, extreme temperatures, and organisms adapted to conserve water.

➡️ What is a desert?

400

The gradual change in ecosystems over time is known as this.

➡️ What is ecological succession?

500

This type of graph is best used to show how one variable changes in response to another, often showing trends over time.

➡️ What is a line graph?

500

This is the highest level of organization and includes all interacting organ systems in one living thing.

➡️ What is an organism?

500

These are the two types of eukaryotic cells.

➡️ What are plant and animal cells? 

500

This biome has permafrost, low biodiversity, and extremely cold temperatures most of the year.

➡️ What is the tundra?

500

This type of symbiotic relationship benefits both species involved.

➡️ What is mutualism?
