Biology EOC Review

Front

What is commensalism?

Back

A type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed. Example: Cattle egrets feeding among cattle.

Front

What type of cell has no nucleus?

Back

Prokaryote - a cell that lacks a membrane-bound nucleus, such as bacteria.

Front

In an experiment, what is the independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable. Example: The type of liquid given to plants.

Front

What temperature does the enzyme work best at according to the graph?

Back

30 C - the optimal temperature for enzyme activity as indicated by the graph.

Front

What does exponential growth represent in a graph?

Back

Exponential growth shows a rapid increase in population size when resources are unlimited, often depicted as a J-shaped curve.

Front

Define mutualism.

Back

A symbiotic relationship where both organisms benefit. Example: Bees pollinating flowers while obtaining nectar.

Front

What is a eukaryote?

Back

A type of cell that has a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment. Example: The growth of plants in response to different liquids.

Front

What is logistic growth?

Back

A model of population growth that accounts for carrying capacity, resulting in an S-shaped curve.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are catalysts that speed up chemical reactions in the body without being consumed in the process.
