Intro to Biology

The scientific study of life.

The cell is the basic unit of life.

Hereditary information is encoded in DNA and functional units called genes.

All life forms have changed over time from a common ancestor through natural selection.

Living organisms maintain a stable internal environment despite external changes.

Living things exhibit complex and structured arrangements, from cells to ecosystems.

The chemical reactions that occur in an organism to acquire and use energy.

The process by which organisms increase in size and complexity during their life cycle.

The production of offspring, either sexually or asexually.

The capacity of living things to detect and respond to changes in their environment.

Change in the genetic makeup of a population over generations.

Regulation of the internal environment to maintain stability.

Atoms combine to form molecules fundamental to life processes.

The basic structural and functional unit of all known living organisms.

Groups of similar cells performing a specific function.

Different tissues working together to perform a specific function.

Groups of organs that cooperate to perform major bodily functions.

An individual living being.

Groups of individuals of the same species living in the same area.

Populations of different species interacting with each other in a specific location.
