Evolution accounts for?
Life’s unity and diversity
Biologists use what to explore life?
Various forms of inquiry
Biology
Scientific study of life
Biosphere
The sum of all ecosystems and where life exists, also known as the ecosphere
Ecosystem
An area where living and nonliving things work together to form a bubble of life
Community
A group of populations of multiple different species occupying the same area.
Population
A group of individuals of the same species that live in the same area and produce fertile offspring
Organism
An individual living thing, consisting of one or more cells
Organ
Specialized center of body function, composed of different types of tissue.
Organ system
A group of organs that work together and perform vital body functions.
Tissues
Integrated group of cells with a common structure, function or both.
Cells
Life’s fundamental units of structure and function, the smallest units of organization that can perform all activities for life
Organelles
Membrane enclosed structures with specialized functions, suspended in the cytosol of eukaryotic cells
Molecule
Two or more atoms held together by covalent bonds
How do DNA nucleotides relate to proteins?
All forms of life use the same genetic code which allows the engineering of cells to produce protein.
How many kids of DNA nucleotides are there?
4
What type of diverse specialist might be involved in a systems biology team?
Biochemists
How can systems biology impact medical practice?
Personalizing medicine for individuals
What are the main criteria for separating plants, fungi, and animals kingdoms?
Separated based on molecular data, which is then split into three domains.
What are the 3 domains?
Domain archaea, domain bacteria, and domain eukarya.
Darwin’s theory of natural selection through evolution
Organisms with the best traits for an environment will continue to evolve.
Heritable information
DNA, which is responsible for making each person unique.
Emergent properties of biological systems
Small parts of the biological system interact which results in creation of properties that individuals don’t have.
