abiotic, or nonliving, parts of that environment
• biosphere -✓✓the collection of all ecosystems on Earth
• emergent properties -✓✓characteristics of a system that do not appear in any one of
its component parts alone, but that appear when all parts are combined.
• Biome -✓✓Areas of the earth with similar characteristics of living and nonliving things
• What is the first level of organization that is alive? -✓✓The cell

(2) molecule
(3) organelles
(4) cell
(5) tissue
(6) organs
,(7) organ system
(8) organisms
(9) population

• Energy flows through -✓✓living systems
• matter is -✓✓recycled
• Life's components are interconnected -✓✓and interdependent.
• Organisms grow -✓✓develop, and reproduce
• Evolutionary processes explain both -✓✓the unity and adaptive diversity of life
• homeostasis -✓✓The ability or tendency of organisms and cells to maintain stable
internal conditions.
• Matter is made up of -✓✓Atoms
• Any matter an organism needs but cannot make for itself is considered -✓✓a nutrient
• When an organism releases matter, the excreted matter is considered -✓✓waste
• Waste -✓✓Urine, feces, exhaled breath
• Reproduction -✓✓occurs when an individual organism passes on its genetic
information to a newly independent organism, or offspring
, • Energy -✓✓the capacity to do work or to make a change in the location, temperature,
or structure of matter.
• chemical potential energy -✓✓what the substance can do if it is put through a chemical
reaction, like burning, that will release its stored energy
• Chemical potential energy is measured in units called -✓✓calories
• development -✓✓structure and function change in an orderly way as an organism
passes through its life cycle
• DNA -✓✓the molecule of inheritance, encodes proteins and other molecules that build
cells and make them work
• Genes -✓✓recipes for proteins
• Evolution -✓✓scientific theory that explains how and why life changes over time
• The two fundamental tenents of evolution are -✓✓shared ancestry and natural
selection.
• Natural selection -✓✓helps explain how groups of organisms become well-suited, or
adapted, to their surroundings
• Evolution does NOT occur within an individual; evolution happens at the level of the
population. -✓✓True
• scientific experiment -✓✓carefully organized procedure in which the scientist
intervenes in a system to change something, then observes the result of the change
