(50 cards)
an organized way of using evidence to learn about the natural world.
Science
Scientific Method Steps
observation, question, hypothesis, experiment, analysis, conclusion
the science that employs a scientific method to study living things.
Biology
made of many different molecules
Living systems
the base unit of matter.
molecule
They run our body, hold information for how to run our body, provide the energy to do so, and much more
molecules
made up of cells, they reproduce, have a genetic code, grow and develop, use materials and energy, respond to their environment, and change over time.
living systems
German botanist Matthew Schneider, 1838
Concluded that all plants were made of cells
German botanist Theodore Schwann, 1838
Concluded that all animals were made of cells
German physician Rudolf Virchow, 1855
Concluded that cells could be produced only from the division of existing cells
the ability to maintain a relatively stable internal environment in an ever-changing outside world or your body
homeostasis
A set of things working together as parts of a mechanism or a inter-connective network
System
information about reactions to a product, a person’s performance of a task, etc. which is then used a basis for improvement
Feedback
stabilizes a process by reducing its rate or output when it’s effects are too great
Negative Feedback
amplifies or magnifies the change or output
Positive Feedback
a three-dimensional representation of a person or thing or of a proposed structure, typically on a smaller scale than the original
model
properties that are not evident in the individual components of a system, but show up when combining those components.
emergent properties
step-by-step method to answer questions
Scientific Method
Scientific Inquiry
evidence/observation/experiments
The branch of science that studies matter, what it is, and how it changes
Chemistry
a biological community of interacting organisms and their physical environment
ecosystem
a collection of tissues that structurally form a structural unit specialized to perform a particular function
organ
an individual animal, plant, or unicellular life form
organism
a living thing that has an effect on an ecosystem
biotic factor
