Front

What does it mean for cells to need energy?

Back

Cells need energy to perform essential functions, such as growth, reproduction, and maintaining homeostasis. An example is an amoeba consuming a paramecium for energy.

Front

What are the characteristics of a living thing?

Back

Characteristics of living things include being made of cells, passing on traits, and using energy.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between variables in an experiment.

Front

What is the difference between qualitative and quantitative observations?
