Study Notes
Unifying Themes in Biology
- Unity and diversity are two of the unifying themes in biology, which highlight the shared characteristics and diverse forms of life on Earth.
Hereditary Information
- All organisms process hereditary information through DNA (deoxyribonucleic acid) or RNA (ribonucleic acid), which contain the genetic instructions for growth, development, and function.
Essential Life Processes
- Energy and chemical reactions allow organisms to move, grow, and reproduce, which are essential processes for life.
Levels of Organization
- Biologists study life at multiple levels of organization, including molecules, cells, organisms, populations, communities, ecosystems, and the biosphere.
Diverse Forms of Life
- One of the immensely diverse forms of life studied by biologists is prokaryotes, which are single-celled microorganisms that lack a true nucleus, such as bacteria.
