What does it mean for living things to respond to stimuli?

Back

Responding to stimuli means that living things can react to changes in their environment, such as light, temperature, or sound.

Front

How do scientists classify living things?

Back

Scientists classify living things based on similarities in their characteristics, such as structure, function, and genetic makeup.

Front

What is the characteristic of living things that involves growth and development?

Back

Growth and development refer to the process by which living things increase in size and mature over time.

Front

What is a dependent variable in an experiment?

Back

A dependent variable is the variable that is measured in an experiment; it is affected by changes in the independent variable.

What is the difference between an independent variable and a dependent variable?

Back

The independent variable is the one that is changed or controlled in an experiment, while the dependent variable is what is measured.

Front

What are the basic characteristics of all living things?

Back

All living things share characteristics such as being made of cells, using energy, growing and developing, responding to stimuli, and maintaining homeostasis.

Front

What does it mean for living things to evolve?

Back

Evolving means that living things change over time as populations adapt to their environments through natural selection.

Front

What is the role of energy in living organisms?

Back

Energy is essential for all living organisms as it powers their biological processes, such as growth, reproduction, and movement.

Front

What is the significance of cells in living organisms?

Back

Cells are the basic building blocks of all living organisms; they perform essential functions necessary for life.
