Unit 1: BIOLOGICAL BASIS OF LIFE Flashcards
- a systematic study of anything that can be examined, tested, and verified
Sciences
science is derived from the latin word?
scientia meaning “to know”
investigates the relationships between things that can be measured or quantified in either a real or abstract form.
Mathematical Science
investigate the nature and behavior of matter and energy on a vast range of sizes and scales.
Physical Sciences
- examine the structure and composition of our planet, and the physical processes that have helped to shape it.
Earth sciences
- scientific knowledge is put to practical ends.
Technology
- general study of the origin, development, structure, function, evolution, and distribution of living things.
Life sciences/Biology
Unifying Themes
Energy
Evolution
Stability
System and Interactions
Unity and diversity
- organisms require energy to grow and reproduce.
Energy
- changes in living things through time explain the inherited similarities and the diversity in all forms of life.
Evolution
- biological systems tend to achieve a stable equilibrium.
Stability
-communities of organisms interact with the environment
-human body systems (organs) interact to carry on life functions
Systems and interactions
displaying certain similarities to other organisms
Unity and diversity
Three main branches of Biology
- Botany
- Microbiology
- Zoology
- objective, logical, and repeatable attempt to understand the principles and forces operating in the natural universe.
Science
- logical and rational order of steps by which scientists come to conclusions about the world around them.
Scientific Method
define the problem you wish to explain
Define
one or more falsifiable explanations for the observation.
hypothesis
Controlled attempts to test one or more hypotheses. This is the part of the scientific method that tests your hypothesis.
Experimentation
After this step, the hypothesis is either modified or rejected, which causes a repeat of the steps above.
Conclusion
“an educated guess”
Hypothesis
- a widely accepted explanation of natural phenomena;
- a hypothesis that has been repeatedly tested with little modification
Theory
- a statement of what always occurs under certain conditions
- one of the fundamental underlying principles of how the Universe is organized
Law
- Any activity made by living organisms.
