Characteristics of Life, Homeostasis, and Variables

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

Why is negative feedback important for homeostasis?

Back

Negative feedback helps the body return to a set point after a disturbance, ensuring stability.

Front

What is a dependent variable?

Back

The dependent variable is the variable that is measured or observed in an experiment.

Front

What is an independent variable?

Back

The independent variable is the variable that is manipulated or changed in an experiment to observe its effect.

Front

What is a control group?

Back

A control group is a standard for comparison in an experiment, which does not receive the experimental treatment.

Front

Why is it important to have both experimental and control groups?

Back

Having both groups allows for comparison of the effects of the independent variable against a baseline.

Front

What is the purpose of a hypothesis in an experiment?

Back

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

Front

What is the scientific method?

Back

The scientific method is a systematic approach to inquiry that involves observation, hypothesis formation, experimentation, and conclusion.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

Front

What is an experiment?

Back

An experiment is a controlled procedure carried out to test a hypothesis and observe the effects of changing variables.
