Introduction to Biology

Front

What is homeostasis?

Back

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

Front

What does it mean to acquire and use energy?

Back

It refers to the ability of living organisms to obtain energy from their environment and utilize it for growth, reproduction, and other life processes.

Front

What is the difference between growth and development?

Back

Growth refers to an increase in size or mass, while development refers to the process of change that leads to maturity and the formation of adult structures.

Front

What is sexual reproduction?

Back

Sexual reproduction is a type of reproduction that involves the combination of genetic material from two parents, resulting in offspring that are genetically distinct from both parents.

Front

What does biology study?

Back

Biology is the study of life and living organisms, including their structure, function, growth, evolution, and interactions with their environment.

Front

What is metabolism?

Back

Metabolism encompasses all the chemical reactions that occur within a living organism to maintain life, including those that break down nutrients for energy and those that build cellular structures.

Front

What is evolution?

Back

Evolution is the process through which species change over time through mechanisms such as natural selection, leading to the adaptation of organisms to their environment.

Front

What are the characteristics of living things?

Back

Living things exhibit characteristics such as growth, reproduction, response to stimuli, metabolism, homeostasis, and cellular organization.

Front

What is asexual reproduction?

Back

Asexual reproduction is a type of reproduction that involves a single parent and produces offspring that are genetically identical to the parent.

Front

What does it mean to be made of cells?

Back

Being made of cells means that all living organisms are composed of one or more cells, which are the basic units of life.
